-The description from it's GitHub page:
-*EasyAnimate is a pipeline based on the transformer architecture, designed for generating AI images and videos, and for training baseline models and Lora models for Diffusion Transformer. We support direct prediction from pre-trained EasyAnimate models, allowing for the generation of videos with various resolutions, approximately 6 seconds in length, at 8fps (EasyAnimateV5.1, 1 to 49 frames). Additionally, users can train their own baseline and Lora models for specific style transformations.*
-
-This pipeline was contributed by [bubbliiiing](https://github.com/bubbliiiing). The original codebase can be found [here](https://huggingface.co/alibaba-pai). The original weights can be found under [hf.co/alibaba-pai](https://huggingface.co/alibaba-pai).
-
-There are two official EasyAnimate checkpoints for text-to-video and video-to-video.

-For the EasyAnimateV5.1 series:
-- Text-to-video (T2V) and Image-to-video (I2V) works for multiple resolutions. The width and height can vary from 256 to 1024.
-- Both T2V and I2V models support generation with 1~49 frames and work best at this value. Exporting videos at 8 FPS is recommended.

-## Quantization
-
-Quantization helps reduce the memory requirements of very large models by storing model weights in a lower precision data type. However, quantization may have varying impact on video quality depending on the video model.
-

-## Optimize
 
-Flux is a very large model and requires ~50GB of RAM/VRAM to load all the modeling components. Enable some of the optimizations below to lower the memory requirements.
-
-### Group offloading
-
-[Group offloading](../../optimization/memory#group-offloading) lowers VRAM usage by offloading groups of internal layers rather than the whole model or weights. You need to use [`~hooks.apply_group_offloading`] on all the model components of a pipeline. The `offload_type` parameter allows you to toggle between block and leaf-level offloading. Setting it to `leaf_level` offloads the lowest leaf-level parameters to the CPU instead of offloading at the module-level.
-
-On CUDA devices that support asynchronous data streaming, set `use_stream=True` to overlap data transfer and computation to accelerate inference.
-
-> [!TIP]
-> It is possible to mix block and leaf-level offloading for different components in a pipeline.

-### Running FP16 inference
+## Running FP16 inference
 
 Flux can generate high-quality images with FP16 (i.e. to accelerate inference on Turing/Volta GPUs) but produces different outputs compared to FP32/BF16. The issue is that some activations in the text encoders have to be clipped when running in FP16, which affects the overall image. Forcing text encoders to run with FP32 inference thus removes this output difference. See [here](https://github.com/huggingface/diffusers/pull/9097#issuecomment-2272292516) for details.

-Marigold was proposed in 
-[Repurposing Diffusion-Based Image Generators for Monocular Depth Estimation](https://huggingface.co/papers/2312.02145), 
-a CVPR 2024 Oral paper by

+Marigold was proposed in [Repurposing Diffusion-Based Image Generators for Monocular Depth Estimation](https://huggingface.co/papers/2312.02145), a CVPR 2024 Oral paper by [Bingxin Ke](http://www.kebingxin.com/), [Anton Obukhov](https://www.obukhov.ai/), [Shengyu Huang](https://shengyuh.github.io/), [Nando Metzger](https://nandometzger.github.io/), [Rodrigo Caye Daudt](https://rcdaudt.github.io/), and [Konrad Schindler](https://scholar.google.com/citations?user=FZuNgqIAAAAJ&hl=en).
+The idea is to repurpose the rich generative prior of Text-to-Image Latent Diffusion Models (LDMs) for traditional computer vision tasks.
+Initially, this idea was explored to fine-tune Stable Diffusion for Monocular Depth Estimation, as shown in the teaser above.
+Later,
+- [Tianfu Wang](https://tianfwang.github.io/) trained the first Latent Consistency Model (LCM) of Marigold, which unlocked fast single-step inference;
+- [Kevin Qu](https://www.linkedin.com/in/kevin-qu-b3417621b/?locale=en_US) extended the approach to Surface Normals Estimation;
+- [Anton Obukhov](https://www.obukhov.ai/) contributed the pipelines and documentation into diffusers (enabled and supported by [YiYi Xu](https://yiyixuxu.github.io/) and [Sayak Paul](https://sayak.dev/)).
 
-Marigold was later extended in the follow-up paper, 
-[Marigold: Affordable Adaptation of Diffusion-Based Image Generators for Image Analysis](https://huggingface.co/papers/2312.02145),

-[Anton Obukhov](https://www.obukhov.ai/), and 
-[Konrad Schindler](https://scholar.google.com/citations?user=FZuNgqIAAAAJ&hl=en).
-This work expanded Marigold to support new modalities such as **Surface Normals** and **Intrinsic Image Decomposition** 
-(IID), introduced a training protocol for **Latent Consistency Models** (LCM), and demonstrated **High-Resolution** (HR) 
-processing capability.

-<Tip>
-
-The early Marigold models (`v1-0` and earlier) were optimized for best results with at least 10 inference steps.
-LCM models were later developed to enable high-quality inference in just 1 to 4 steps.
-Marigold models `v1-1` and later use the DDIM scheduler to achieve optimal 
-results in as few as 1 to 4 steps.

-</Tip>
+*Monocular depth estimation is a fundamental computer vision task. Recovering 3D depth from a single image is geometrically ill-posed and requires scene understanding, so it is not surprising that the rise of deep learning has led to a breakthrough. The impressive progress of monocular depth estimators has mirrored the growth in model capacity, from relatively modest CNNs to large Transformer architectures. Still, monocular depth estimators tend to struggle when presented with images with unfamiliar content and layout, since their knowledge of the visual world is restricted by the data seen during training, and challenged by zero-shot generalization to new domains. This motivates us to explore whether the extensive priors captured in recent generative diffusion models can enable better, more generalizable depth estimation. We introduce Marigold, a method for affine-invariant monocular depth estimation that is derived from Stable Diffusion and retains its rich prior knowledge. The estimator can be fine-tuned in a couple of days on a single GPU using only synthetic training data. It delivers state-of-the-art performance across a wide range of datasets, including over 20% performance gains in specific cases. Project page: https://marigoldmonodepth.github.io.*
 
 ## Available Pipelines
 
-Each pipeline is tailored for a specific computer vision task, processing an input RGB image and generating a 
-corresponding prediction.
-Currently, the following computer vision tasks are implemented:
+Each pipeline supports one Computer Vision task, which takes an input RGB image as input and produces a *prediction* of the modality of interest, such as a depth map of the input image.
+Currently, the following tasks are implemented:

 <Tip warning={true}>
 
-Marigold pipelines were designed and tested with the scheduler embedded in the model checkpoint.
-The optimal number of inference steps varies by scheduler, with no universal value that works best across all cases.
-To accommodate this, the `num_inference_steps` parameter in the pipeline's `__call__` method defaults to `None` (see the 
-API reference).
-Unless set explicitly, it inherits the value from the `default_denoising_steps` field in the checkpoint configuration 
-file (`model_index.json`).
-This ensures high-quality predictions when invoking the pipeline with only the `image` argument.
+Marigold pipelines were designed and tested only with `DDIMScheduler` and `LCMScheduler`.
+Depending on the scheduler, the number of inference steps required to get reliable predictions varies, and there is no universal value that works best across schedulers.
+Because of that, the default value of `num_inference_steps` in the `__call__` method of the pipeline is set to `None` (see the API reference).
+Unless set explicitly, its value will be taken from the checkpoint configuration `model_index.json`.
+This is done to ensure high-quality predictions when calling the pipeline with just the `image` argument.

-## Memory Optimizations for Wan 2.1
-
-Base inference with the large 14B Wan 2.1 models can take up to 35GB of VRAM when generating videos at 720p resolution. We'll outline a few memory optimizations we can apply to reduce the VRAM required to run the model.
-
-We'll use `Wan-AI/Wan2.1-I2V-14B-720P-Diffusers` model in these examples to demonstrate the memory savings, but the techniques are applicable to all model checkpoints.

-
-#### Block Level Group Offloading
-
-We can reduce our VRAM requirements by applying group offloading to the larger model components of the pipeline; the `WanTransformer3DModel` and `UMT5EncoderModel`. Group offloading will break up the individual modules of a model and offload/onload them onto your GPU as needed during inference. In this example, we'll apply `block_level` offloading, which will group the modules in a model into blocks of size `num_blocks_per_group` and offload/onload them to GPU. Moving to between CPU and GPU does add latency to the inference process. You can trade off between latency and memory savings by increasing or decreasing the `num_blocks_per_group`.
-
-The following example will now only require 14GB of VRAM to run, but will take approximately 30 minutes to generate a video.

-#### Block Level Group Offloading with CUDA Streams
-
-We can speed up group offloading inference, by enabling the use of [CUDA streams](https://pytorch.org/docs/stable/generated/torch.cuda.Stream.html). However, using CUDA streams requires moving the model parameters into pinned memory. This allocation is handled by Pytorch under the hood, and can result in a significant spike in CPU RAM usage. Please consider this option if your CPU RAM is atleast 2X the size of the model you are group offloading.
-
-In the following example we will use CUDA streams when group offloading the `WanTransformer3DModel`. When testing on an A100, this example will require 14GB of VRAM, 52GB of CPU RAM, but will generate a video in approximately 9 minutes.

-
-### Applying Layerwise Casting to the Transformer
-
-Find more information about layerwise casting [here](../optimization/memory.md)
-
-In this example, we will model offloading with layerwise casting. Layerwise casting will downcast each layer's weights to `torch.float8_e4m3fn`, temporarily upcast to `torch.bfloat16` during the forward pass of the layer, then revert to `torch.float8_e4m3fn` afterward. This approach reduces memory requirements by approximately 50% while introducing a minor quality reduction in the generated video due to the precision trade-off.
-
-This example will require 20GB of VRAM.

-### Using a Custom Scheduler
-
-Wan can be used with many different schedulers, each with their own benefits regarding speed and generation quality. By default, Wan uses the `UniPCMultistepScheduler(prediction_type="flow_prediction", use_flow_sigmas=True, flow_shift=3.0)` scheduler. You can use a different scheduler as follows:
-
-```python
-from diffusers import FlowMatchEulerDiscreteScheduler, UniPCMultistepScheduler, WanPipeline
-
-scheduler_a = FlowMatchEulerDiscreteScheduler(shift=5.0)
-scheduler_b = UniPCMultistepScheduler(prediction_type="flow_prediction", use_flow_sigmas=True, flow_shift=4.0)
-
-pipe = WanPipeline.from_pretrained("Wan-AI/Wan2.1-T2V-1.3B-Diffusers", scheduler=<CUSTOM_SCHEDULER_HERE>)
-
-# or,
-pipe.scheduler = <CUSTOM_SCHEDULER_HERE>
-```
-
-## Using Single File Loading with Wan 2.1
-
-The `WanTransformer3DModel` and `AutoencoderKLWan` models support loading checkpoints in their original format via the `from_single_file` loading
-method.
-
-```python
-import torch
-from diffusers import WanPipeline, WanTransformer3DModel
-
-ckpt_path = "https://huggingface.co/Comfy-Org/Wan_2.1_ComfyUI_repackaged/blob/main/split_files/diffusion_models/wan2.1_t2v_1.3B_bf16.safetensors"
-transformer = WanTransformer3DModel.from_single_file(ckpt_path, torch_dtype=torch.bfloat16)
-
-pipe = WanPipeline.from_pretrained("Wan-AI/Wan2.1-T2V-1.3B-Diffusers", transformer=transformer)
-```
-
-## Recommendations for Inference:
-- Keep `AutencoderKLWan` in `torch.float32` for better decoding quality.
-- `num_frames` should satisfy the following constraint: `(num_frames - 1) % 4 == 0`
-- For smaller resolution videos, try lower values of `shift` (between `2.0` to `5.0`) in the [Scheduler](https://huggingface.co/docs/diffusers/main/en/api/schedulers/flow_match_euler_discrete#diffusers.FlowMatchEulerDiscreteScheduler.shift). For larger resolution videos, try higher values (between `7.0` and `12.0`). The default value is `3.0` for Wan.

 Evaluation of generative models like [Stable Diffusion](https://huggingface.co/docs/diffusers/stable_diffusion) is subjective in nature. But as practitioners and researchers, we often have to make careful choices amongst many different possibilities. So, when working with different generative models (like GANs, Diffusion, etc.), how do we choose one over the other?
 
 Qualitative evaluation of such models can be error-prone and might incorrectly influence a decision.

-# Getting Started: VAE Decode with Hybrid Inference
-
-VAE decode is an essential component of diffusion models - turning latent representations into images or videos.
-
-## Memory
-
-These tables demonstrate the VRAM requirements for VAE decode with SD v1 and SD XL on different GPUs.
-
-For the majority of these GPUs the memory usage % dictates other models (text encoders, UNet/Transformer) must be offloaded, or tiled decoding has to be used which increases time taken and impacts quality.

-A helper method simplifies interacting with Hybrid Inference.
-
-```python
-from diffusers.utils.remote_utils import remote_decode
-```
-
-### Basic example
-
-Here, we show how to use the remote VAE on random tensors.
-
-<details><summary>Code</summary>
-
-```python
-image = remote_decode(
-    endpoint="https://q1bj3bpq6kzilnsu.us-east-1.aws.endpoints.huggingface.cloud/",
-    tensor=torch.randn([1, 4, 64, 64], dtype=torch.float16),
-    scaling_factor=0.18215,
-)
-```

-<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/blog/remote_vae/output.png"/>
-</figure>
-
-Usage for Flux is slightly different. Flux latents are packed so we need to send the `height` and `width`.
-
-<details><summary>Code</summary>
-
-```python
-image = remote_decode(
-    endpoint="https://whhx50ex1aryqvw6.us-east-1.aws.endpoints.huggingface.cloud/",
-    tensor=torch.randn([1, 4096, 64], dtype=torch.float16),
-    height=1024,
-    width=1024,
-    scaling_factor=0.3611,
-    shift_factor=0.1159,
-)
-```
-

-
-Finally, an example for HunyuanVideo.
-
-<details><summary>Code</summary>
-
-```python

-    endpoint="https://o7ywnmrahorts457.us-east-1.aws.endpoints.huggingface.cloud/",
-    tensor=torch.randn([1, 16, 3, 40, 64], dtype=torch.float16),
-    output_type="mp4",
-)
-with open("video.mp4", "wb") as f:
-    f.write(video)
-```

-
-
-### Generation
-
-But we want to use the VAE on an actual pipeline to get an actual image, not random noise. The example below shows how to do it with SD v1.5. 
-
-<details><summary>Code</summary>
-
-```python
-from diffusers import StableDiffusionPipeline
-
-pipe = StableDiffusionPipeline.from_pretrained(
-    "stable-diffusion-v1-5/stable-diffusion-v1-5",
-    torch_dtype=torch.float16,
-    variant="fp16",
-    vae=None,
-).to("cuda")
-
-prompt = "Strawberry ice cream, in a stylish modern glass, coconut, splashing milk cream and honey, in a gradient purple background, fluid motion, dynamic movement, cinematic lighting, Mysterious"
-
-latent = pipe(
-    prompt=prompt,
-    output_type="latent",
-).images
-image = remote_decode(
-    endpoint="https://q1bj3bpq6kzilnsu.us-east-1.aws.endpoints.huggingface.cloud/",
-    tensor=latent,
-    scaling_factor=0.18215,
-)
-image.save("test.jpg")
-```

-
-Here’s another example with Flux.
-
-<details><summary>Code</summary>
-
-```python
-from diffusers import FluxPipeline
-
-pipe = FluxPipeline.from_pretrained(
-    "black-forest-labs/FLUX.1-schnell",

-    vae=None,
-).to("cuda")
-
-prompt = "Strawberry ice cream, in a stylish modern glass, coconut, splashing milk cream and honey, in a gradient purple background, fluid motion, dynamic movement, cinematic lighting, Mysterious"
-
-latent = pipe(
-    prompt=prompt,
-    guidance_scale=0.0,
-    num_inference_steps=4,
-    output_type="latent",
-).images
-image = remote_decode(
-    endpoint="https://whhx50ex1aryqvw6.us-east-1.aws.endpoints.huggingface.cloud/",

-Here’s an example with HunyuanVideo.
-
-<details><summary>Code</summary>
-
-```python
-from diffusers import HunyuanVideoPipeline, HunyuanVideoTransformer3DModel

-### Queueing
-
-One of the great benefits of using a remote VAE is that we can queue multiple generation requests. While the current latent is being processed for decoding, we can already queue another one. This helps improve concurrency.

-<details><summary>Code</summary>
-
-```python
-import queue
-import threading
-from IPython.display import display
-from diffusers import StableDiffusionPipeline
-
-def decode_worker(q: queue.Queue):
-    while True:
-        item = q.get()
-        if item is None:
-            break
-        image = remote_decode(
-            endpoint="https://q1bj3bpq6kzilnsu.us-east-1.aws.endpoints.huggingface.cloud/",
-            tensor=item,
-            scaling_factor=0.18215,
-        )
-        display(image)
-        q.task_done()
-
-q = queue.Queue()
-thread = threading.Thread(target=decode_worker, args=(q,), daemon=True)
-thread.start()
-
-def decode(latent: torch.Tensor):
-    q.put(latent)
-

-# Getting Started: VAE Encode with Hybrid Inference
-
-VAE encode is used for training, image-to-image and image-to-video - turning into images or videos into latent representations.
-
-## Memory
-
-These tables demonstrate the VRAM requirements for VAE encode with SD v1 and SD XL on different GPUs.
-
-For the majority of these GPUs the memory usage % dictates other models (text encoders, UNet/Transformer) must be offloaded, or tiled encoding has to be used which increases time taken and impacts quality.

-# Quanto
-
-[Quanto](https://github.com/huggingface/optimum-quanto) is a PyTorch quantization backend for [Optimum](https://huggingface.co/docs/optimum/en/index). It has been designed with versatility and simplicity in mind:
-
-- All features are available in eager mode (works with non-traceable models)
-- Supports quantization aware training
-- Quantized models are compatible with `torch.compile`
-- Quantized models are Device agnostic (e.g CUDA,XPU,MPS,CPU)
-
-In order to use the Quanto backend, you will first need to install `optimum-quanto>=0.2.6` and `accelerate`
-
-```shell
-pip install optimum-quanto accelerate
-```
-
-Now you can quantize a model by passing the `QuantoConfig` object to the `from_pretrained()` method. Although the Quanto library does allow quantizing `nn.Conv2d` and `nn.LayerNorm` modules, currently, Diffusers only supports quantizing the weights in the `nn.Linear` layers of a model. The following snippet demonstrates how to apply `float8` quantization with Quanto.   
-
-```python
-import torch
-from diffusers import FluxTransformer2DModel, QuantoConfig
-
-model_id = "black-forest-labs/FLUX.1-dev"
-quantization_config = QuantoConfig(weights_dtype="float8")
-transformer = FluxTransformer2DModel.from_pretrained(
-      model_id,
-      subfolder="transformer",
-      quantization_config=quantization_config,
-      torch_dtype=torch.bfloat16,
-)
-
-pipe = FluxPipeline.from_pretrained(model_id, transformer=transformer, torch_dtype=torch_dtype)
-pipe.to("cuda")
-
-prompt = "A cat holding a sign that says hello world"
-image = pipe(
-    prompt, num_inference_steps=50, guidance_scale=4.5, max_sequence_length=512
-).images[0]
-image.save("output.png")
-```
-
-## Skipping Quantization on specific modules
-
-It is possible to skip applying quantization on certain modules using the `modules_to_not_convert` argument in the `QuantoConfig`. Please ensure that the modules passed in to this argument match the keys of the modules in the `state_dict`  
-
-```python
-import torch
-from diffusers import FluxTransformer2DModel, QuantoConfig
-
-model_id = "black-forest-labs/FLUX.1-dev"
-quantization_config = QuantoConfig(weights_dtype="float8", modules_to_not_convert=["proj_out"])
-transformer = FluxTransformer2DModel.from_pretrained(
-      model_id,
-      subfolder="transformer",
-      quantization_config=quantization_config,
-      torch_dtype=torch.bfloat16,
-)
-```
-
-## Using `from_single_file` with the Quanto Backend
-
-`QuantoConfig` is compatible with `~FromOriginalModelMixin.from_single_file`. 
-
-```python
-import torch
-from diffusers import FluxTransformer2DModel, QuantoConfig
-
-ckpt_path = "https://huggingface.co/black-forest-labs/FLUX.1-dev/blob/main/flux1-dev.safetensors"
-quantization_config = QuantoConfig(weights_dtype="float8")
-transformer = FluxTransformer2DModel.from_single_file(ckpt_path, quantization_config=quantization_config, torch_dtype=torch.bfloat16)
-```
-
-## Saving Quantized models
-
-Diffusers supports serializing Quanto models using the `~ModelMixin.save_pretrained` method.
-
-The serialization and loading requirements are different for models quantized directly with the Quanto library and models quantized
-with Diffusers using Quanto as the backend. It is currently not possible to load models quantized directly with Quanto into Diffusers using `~ModelMixin.from_pretrained`
-
-```python
-import torch
-from diffusers import FluxTransformer2DModel, QuantoConfig
-
-model_id = "black-forest-labs/FLUX.1-dev"
-quantization_config = QuantoConfig(weights_dtype="float8")
-transformer = FluxTransformer2DModel.from_pretrained(
-      model_id,
-      subfolder="transformer",
-      quantization_config=quantization_config,
-      torch_dtype=torch.bfloat16,
-)
-# save quantized model to reuse
-transformer.save_pretrained("<your quantized model save path>")
-
-# you can reload your quantized model with
-model = FluxTransformer2DModel.from_pretrained("<your quantized model save path>")
-```
-
-## Using `torch.compile` with Quanto
-
-Currently the Quanto backend supports `torch.compile` for the following quantization types:
-
-- `int8` weights 
-
-```python
-import torch
-from diffusers import FluxPipeline, FluxTransformer2DModel, QuantoConfig
-
-model_id = "black-forest-labs/FLUX.1-dev"
-quantization_config = QuantoConfig(weights_dtype="int8")
-transformer = FluxTransformer2DModel.from_pretrained(
-    model_id,
-    subfolder="transformer",
-    quantization_config=quantization_config,
-    torch_dtype=torch.bfloat16,
-)
-transformer = torch.compile(transformer, mode="max-autotune", fullgraph=True)
-
-pipe = FluxPipeline.from_pretrained(
-    model_id, transformer=transformer, torch_dtype=torch_dtype

-If you are using `torch<=2.6.0`, some quantization methods, such as `uint4wo`, cannot be loaded directly and may result in an `UnpicklingError` when trying to load the models, but work as expected when saving them. In order to work around this, one can load the state dict manually into the model. Note, however, that this requires using `weights_only=False` in `torch.load`, so it should be run only if the weights were obtained from a trustable source.

-## IP Adapter Cutoff
-
-IP Adapter is an image prompt adapter that can be used for diffusion models without any changes to the underlying model. We can use the IP Adapter Cutoff Callback to disable the IP Adapter after a certain number of steps. To set up the callback, you need to specify the number of denoising steps after which the callback comes into effect. You can do so by using either one of these two arguments:
-
-- `cutoff_step_ratio`: Float number with the ratio of the steps.
-- `cutoff_step_index`: Integer number with the exact number of the step.
-
-We need to download the diffusion model and load the ip_adapter for it as follows:
-
-```py
-from diffusers import AutoPipelineForText2Image
-from diffusers.utils import load_image
-import torch
-
-pipeline = AutoPipelineForText2Image.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0", torch_dtype=torch.float16).to("cuda")

-## Intrinsic Image Decomposition
+### Speeding up inference
 
-Marigold provides two models for Intrinsic Image Decomposition (IID): "Appearance" and "Lighting". 
-Each model produces Albedo maps, derived from InteriorVerse and Hypersim annotations, respectively.
-
-- The "Appearance" model also estimates Material properties: Roughness and Metallicity.
-- The "Lighting" model generates Diffuse Shading and Non-diffuse Residual.
-
-Here is the sample code saving predictions made by the "Appearance" model:
-
-```python
-import diffusers
-import torch
-
-pipe = diffusers.MarigoldIntrinsicsPipeline.from_pretrained(
-    "prs-eth/marigold-iid-appearance-v1-1", variant="fp16", torch_dtype=torch.float16
-).to("cuda")
-
-image = diffusers.utils.load_image("https://marigoldmonodepth.github.io/images/einstein.jpg")
-
-intrinsics = pipe(image)
-
-vis = pipe.image_processor.visualize_intrinsics(intrinsics.prediction, pipe.target_properties)
-vis[0]["albedo"].save("einstein_albedo.png")
-vis[0]["roughness"].save("einstein_roughness.png")
-vis[0]["metallicity"].save("einstein_metallicity.png")
-```
-
-Another example demonstrating the predictions made by the "Lighting" model:
-
-```python
-import diffusers
-import torch
-
-pipe = diffusers.MarigoldIntrinsicsPipeline.from_pretrained(
-    "prs-eth/marigold-iid-lighting-v1-1", variant="fp16", torch_dtype=torch.float16
-).to("cuda")
-
-image = diffusers.utils.load_image("https://marigoldmonodepth.github.io/images/einstein.jpg")
-
-intrinsics = pipe(image)
-
-vis = pipe.image_processor.visualize_intrinsics(intrinsics.prediction, pipe.target_properties)
-vis[0]["albedo"].save("einstein_albedo.png")
-vis[0]["shading"].save("einstein_shading.png")
-vis[0]["residual"].save("einstein_residual.png")
-```
-
-Both models share the same pipeline while supporting different decomposition types.
-The exact decomposition parameterization (e.g., sRGB vs. linear space) is stored in the 
-`pipe.target_properties` dictionary, which is passed into the 
-[`~pipelines.marigold.marigold_image_processing.MarigoldImageProcessor.visualize_intrinsics`] function.

-## Speeding up inference
-
-The above quick start snippets are already optimized for quality and speed, loading the checkpoint, utilizing the 
-`fp16` variant of weights and computation, and performing the default number (4) of denoising diffusion steps.
-The first step to accelerate inference, at the expense of prediction quality, is to reduce the denoising diffusion 
-steps to the minimum:
+The above quick start snippets are already optimized for speed: they load the LCM checkpoint, use the `fp16` variant of weights and computation, and perform just one denoising diffusion step.
+The `pipe(image)` call completes in 280ms on RTX 3090 GPU.
+Internally, the input image is encoded with the Stable Diffusion VAE encoder, then the U-Net performs one denoising step, and finally, the prediction latent is decoded with the VAE decoder into pixel space.
+In this case, two out of three module calls are dedicated to converting between pixel and latent space of LDM.
+Because Marigold's latent space is compatible with the base Stable Diffusion, it is possible to speed up the pipeline call by more than 3x (85ms on RTX 3090) by using a [lightweight replacement of the SD VAE](../api/models/autoencoder_tiny):

-step performed by the U-Net. 
-Finally, the prediction latent is decoded with the VAE decoder into pixel space.
-In this setup, two out of three module calls are dedicated to converting between the pixel and latent spaces of the LDM.
-Since Marigold's latent space is compatible with Stable Diffusion 2.0, inference can be accelerated by more than 3x, 
-reducing the call time to 85ms on an RTX 3090, by using a [lightweight replacement of the SD VAE](../api/models/autoencoder_tiny).

 ## Maximizing Precision and Ensembling
 
 Marigold pipelines have a built-in ensembling mechanism combining multiple predictions from different random latents.
 This is a brute-force way of improving the precision of predictions, capitalizing on the generative nature of diffusion.
-The ensembling path is activated automatically when the `ensemble_size` argument is set greater or equal than `3`.
+The ensembling path is activated automatically when the `ensemble_size` argument is set greater than `1`.
 When aiming for maximum precision, it makes sense to adjust `num_inference_steps` simultaneously with `ensemble_size`.
 The recommended values vary across checkpoints but primarily depend on the scheduler type.
 The effect of ensembling is particularly well-seen with surface normals:

+## Using Predictive Uncertainty
+
+The ensembling mechanism built into Marigold pipelines combines multiple predictions obtained from different random latents.
+As a side effect, it can be used to quantify epistemic (model) uncertainty; simply specify `ensemble_size` greater than 1 and set `output_uncertainty=True`.
+The resulting uncertainty will be available in the `uncertainty` field of the output.

+
+```python

 Prompt weighting provides a way to emphasize or de-emphasize certain parts of a prompt, allowing for more control over the generated image. A prompt can include several concepts, which gets turned into contextualized text embeddings. The embeddings are used by the model to condition its cross-attention layers to generate an image (read the Stable Diffusion [blog post](https://huggingface.co/blog/stable_diffusion) to learn more about how it works).

+### Weighting
+
+You'll notice there is no "ball" in the image! Let's use compel to upweight the concept of "ball" in the prompt. Create a [`Compel`](https://github.com/damian0815/compel/blob/main/doc/compel.md#compel-objects) object, and pass it a tokenizer and text encoder:
+
+```py
+from compel import Compel
+
+compel_proc = Compel(tokenizer=pipe.tokenizer, text_encoder=pipe.text_encoder)
+```
+
+compel uses `+` or `-` to increase or decrease the weight of a word in the prompt. To increase the weight of "ball":
+
+<Tip>
+
+`+` corresponds to the value `1.1`, `++` corresponds to `1.1^2`, and so on. Similarly, `-` corresponds to `0.9` and `--` corresponds to `0.9^2`. Feel free to experiment with adding more `+` or `-` in your prompt!
+
+</Tip>
+
+```py
+prompt = "a red cat playing with a ball++"
+```
+
+Pass the prompt to `compel_proc` to create the new prompt embeddings which are passed to the pipeline:
+
+```py
+prompt_embeds = compel_proc(prompt)
+generator = torch.manual_seed(33)
+
+image = pipe(prompt_embeds=prompt_embeds, generator=generator, num_inference_steps=20).images[0]
+image
+```
+
+<div class="flex justify-center">
+  <img class="rounded-xl" src="https://huggingface.co/datasets/hf-internal-testing/diffusers-images/resolve/main/compel/forest_1.png"/>
+</div>
+
+To downweight parts of the prompt, use the `-` suffix:
+
+```py
+prompt = "a red------- cat playing with a ball"
+prompt_embeds = compel_proc(prompt)
+
+generator = torch.manual_seed(33)
+
+image = pipe(prompt_embeds=prompt_embeds, generator=generator, num_inference_steps=20).images[0]
+image
+```
+
+<div class="flex justify-center">
+  <img class="rounded-xl" src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/compel-neg.png"/>
+</div>
+
+You can even up or downweight multiple concepts in the same prompt:
+
+```py
+prompt = "a red cat++ playing with a ball----"
+prompt_embeds = compel_proc(prompt)
+
+generator = torch.manual_seed(33)
+
+image = pipe(prompt_embeds=prompt_embeds, generator=generator, num_inference_steps=20).images[0]
+image
+```
+
+<div class="flex justify-center">
+  <img class="rounded-xl" src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/compel-pos-neg.png"/>
+</div>
+
+### Blending
+
+You can also create a weighted *blend* of prompts by adding `.blend()` to a list of prompts and passing it some weights. Your blend may not always produce the result you expect because it breaks some assumptions about how the text encoder functions, so just have fun and experiment with it!
+
+```py
+prompt_embeds = compel_proc('("a red cat playing with a ball", "jungle").blend(0.7, 0.8)')
+generator = torch.Generator(device="cuda").manual_seed(33)
+
+image = pipe(prompt_embeds=prompt_embeds, generator=generator, num_inference_steps=20).images[0]

+<div class="flex justify-center">
+  <img class="rounded-xl" src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/compel-blend.png"/>
+</div>
+
+### Conjunction
+
+A conjunction diffuses each prompt independently and concatenates their results by their weighted sum. Add `.and()` to the end of a list of prompts to create a conjunction:
+
+```py
+prompt_embeds = compel_proc('["a red cat", "playing with a", "ball"].and()')
+generator = torch.Generator(device="cuda").manual_seed(55)
+
+image = pipe(prompt_embeds=prompt_embeds, generator=generator, num_inference_steps=20).images[0]

+### Stable Diffusion XL
+
+Stable Diffusion XL (SDXL) has two tokenizers and text encoders so it's usage is a bit different. To address this, you should pass both tokenizers and encoders to the `Compel` class:
+
+```py
+from compel import Compel, ReturnedEmbeddingsType
+from diffusers import DiffusionPipeline
+from diffusers.utils import make_image_grid
+import torch
+
+pipeline = DiffusionPipeline.from_pretrained(
+  "stabilityai/stable-diffusion-xl-base-1.0",
+  variant="fp16",
+  use_safetensors=True,
+  torch_dtype=torch.float16
+).to("cuda")
+
+compel = Compel(
+  tokenizer=[pipeline.tokenizer, pipeline.tokenizer_2] ,
+  text_encoder=[pipeline.text_encoder, pipeline.text_encoder_2],
+  returned_embeddings_type=ReturnedEmbeddingsType.PENULTIMATE_HIDDEN_STATES_NON_NORMALIZED,
+  requires_pooled=[False, True]
+)
+```
+
+This time, let's upweight "ball" by a factor of 1.5 for the first prompt, and downweight "ball" by 0.6 for the second prompt. The [`StableDiffusionXLPipeline`] also requires [`pooled_prompt_embeds`](https://huggingface.co/docs/diffusers/en/api/pipelines/stable_diffusion/stable_diffusion_xl#diffusers.StableDiffusionXLInpaintPipeline.__call__.pooled_prompt_embeds) (and optionally [`negative_pooled_prompt_embeds`](https://huggingface.co/docs/diffusers/en/api/pipelines/stable_diffusion/stable_diffusion_xl#diffusers.StableDiffusionXLInpaintPipeline.__call__.negative_pooled_prompt_embeds)) so you should pass those to the pipeline along with the conditioning tensors:
+
+```py
+# apply weights
+prompt = ["a red cat playing with a (ball)1.5", "a red cat playing with a (ball)0.6"]
+conditioning, pooled = compel(prompt)
+
+# generate image
+generator = [torch.Generator().manual_seed(33) for _ in range(len(prompt))]
+images = pipeline(prompt_embeds=conditioning, pooled_prompt_embeds=pooled, generator=generator, num_inference_steps=30).images
+make_image_grid(images, rows=1, cols=2)

-# Training CogView4 Control
-
-This (experimental) example shows how to train Control LoRAs with [CogView4](https://huggingface.co/THUDM/CogView4-6B) by conditioning it with additional structural controls (like depth maps, poses, etc.). We provide a script for full fine-tuning, too, refer to [this section](#full-fine-tuning). To know more about CogView4 Control family, refer to the following resources:
-
-To incorporate additional condition latents, we expand the input features of CogView-4 from 64 to 128. The first 64 channels correspond to the original input latents to be denoised, while the latter 64 channels correspond to control latents. This expansion happens on the `patch_embed` layer, where the combined latents are projected to the expected feature dimension of rest of the network. Inference is performed using the `CogView4ControlPipeline`.
-
-> [!NOTE]
-> **Gated model**
->
-> As the model is gated, before using it with diffusers you first need to go to the [CogView4 Hugging Face page](https://huggingface.co/THUDM/CogView4-6B), fill in the form and accept the gate. Once you are in, you need to log in so that your system knows you’ve accepted the gate. Use the command below to log in:
-
-```bash
-huggingface-cli login
-```
-
-The example command below shows how to launch fine-tuning for pose conditions. The dataset ([`raulc0399/open_pose_controlnet`](https://huggingface.co/datasets/raulc0399/open_pose_controlnet)) being used here already has the pose conditions of the original images, so we don't have to compute them.
-
-```bash
-accelerate launch train_control_lora_cogview4.py \
-  --pretrained_model_name_or_path="THUDM/CogView4-6B" \
-  --dataset_name="raulc0399/open_pose_controlnet" \
-  --output_dir="pose-control-lora" \
-  --mixed_precision="bf16" \
-  --train_batch_size=1 \
-  --rank=64 \
-  --gradient_accumulation_steps=4 \
-  --gradient_checkpointing \
-  --use_8bit_adam \
-  --learning_rate=1e-4 \
-  --report_to="wandb" \
-  --lr_scheduler="constant" \
-  --lr_warmup_steps=0 \
-  --max_train_steps=5000 \
-  --validation_image="openpose.png" \
-  --validation_prompt="A couple, 4k photo, highly detailed" \
-  --offload \
-  --seed="0" \
-  --push_to_hub
-```
-
-`openpose.png` comes from [here](https://huggingface.co/Adapter/t2iadapter/resolve/main/openpose.png).
-
-You need to install `diffusers` from the branch of [this PR](https://github.com/huggingface/diffusers/pull/9999). When it's merged, you should install `diffusers` from the `main`.
-
-The training script exposes additional CLI args that might be useful to experiment with:
-
-* `use_lora_bias`: When set, additionally trains the biases of the `lora_B` layer. 
-* `train_norm_layers`: When set, additionally trains the normalization scales. Takes care of saving and loading.
-* `lora_layers`: Specify the layers you want to apply LoRA to. If you specify "all-linear", all the linear layers will be LoRA-attached.
-
-### Training with DeepSpeed
-
-It's possible to train with [DeepSpeed](https://github.com/microsoft/DeepSpeed), specifically leveraging the Zero2 system optimization. To use it, save the following config to an YAML file (feel free to modify as needed):
-
-```yaml
-compute_environment: LOCAL_MACHINE
-debug: false
-deepspeed_config:
-  gradient_accumulation_steps: 1
-  gradient_clipping: 1.0
-  offload_optimizer_device: cpu
-  offload_param_device: cpu
-  zero3_init_flag: false
-  zero_stage: 2
-distributed_type: DEEPSPEED
-downcast_bf16: 'no'
-enable_cpu_affinity: false
-machine_rank: 0
-main_training_function: main
-mixed_precision: bf16
-num_machines: 1
-num_processes: 1
-rdzv_backend: static
-same_network: true
-tpu_env: []
-tpu_use_cluster: false
-tpu_use_sudo: false
-use_cpu: false
-```
-
-And then while launching training, pass the config file:
-
-```bash
-accelerate launch --config_file=CONFIG_FILE.yaml ...
-```
-
-### Inference
-
-The pose images in our dataset were computed using the [`controlnet_aux`](https://github.com/huggingface/controlnet_aux) library. Let's install it first:
-
-```bash
-pip install controlnet_aux
-```
-
-And then we are ready:
-
-```py
-from controlnet_aux import OpenposeDetector
-from diffusers import CogView4ControlPipeline
-from diffusers.utils import load_image
-from PIL import Image
-import numpy as np
-import torch 
-
-pipe = CogView4ControlPipeline.from_pretrained("THUDM/CogView4-6B", torch_dtype=torch.bfloat16).to("cuda")
-pipe.load_lora_weights("...") # change this.
-
-open_pose = OpenposeDetector.from_pretrained("lllyasviel/Annotators")
-
-# prepare pose condition.
-url = "https://huggingface.co/Adapter/t2iadapter/resolve/main/people.jpg"
-image = load_image(url)
-image = open_pose(image, detect_resolution=512, image_resolution=1024)
-image = np.array(image)[:, :, ::-1]           
-image = Image.fromarray(np.uint8(image))
-
-prompt = "A couple, 4k photo, highly detailed"
-
-gen_images = pipe(
-  prompt=prompt,
-  control_image=image,
-  num_inference_steps=50,
-  joint_attention_kwargs={"scale": 0.9},
-  guidance_scale=25., 
-).images[0]
-gen_images.save("output.png")
-```
-
-## Full fine-tuning
-
-We provide a non-LoRA version of the training script `train_control_cogview4.py`. Here is an example command:
-
-```bash
-accelerate launch --config_file=accelerate_ds2.yaml train_control_cogview4.py \
-  --pretrained_model_name_or_path="THUDM/CogView4-6B" \
-  --dataset_name="raulc0399/open_pose_controlnet" \
-  --output_dir="pose-control" \
-  --mixed_precision="bf16" \
-  --train_batch_size=2 \
-  --dataloader_num_workers=4 \
-  --gradient_accumulation_steps=4 \
-  --gradient_checkpointing \
-  --use_8bit_adam \
-  --proportion_empty_prompts=0.2 \
-  --learning_rate=5e-5 \
-  --adam_weight_decay=1e-4 \
-  --report_to="wandb" \
-  --lr_scheduler="cosine" \
-  --lr_warmup_steps=1000 \
-  --checkpointing_steps=1000 \
-  --max_train_steps=10000 \
-  --validation_steps=200 \
-  --validation_image "2_pose_1024.jpg" "3_pose_1024.jpg" \
-  --validation_prompt "two friends sitting by each other enjoying a day at the park, full hd, cinematic" "person enjoying a day at the park, full hd, cinematic" \
-  --offload \
-  --seed="0" \
-  --push_to_hub
-```
-
-Change the `validation_image` and `validation_prompt` as needed.
-
-For inference, this time, we will run:
-
-```py
-from controlnet_aux import OpenposeDetector
-from diffusers import CogView4ControlPipeline, CogView4Transformer2DModel
-from diffusers.utils import load_image
-from PIL import Image
-import numpy as np
-import torch 
-
-transformer = CogView4Transformer2DModel.from_pretrained("...") # change this.
-pipe = CogView4ControlPipeline.from_pretrained(
-  "THUDM/CogView4-6B",  transformer=transformer, torch_dtype=torch.bfloat16
-).to("cuda")
-
-open_pose = OpenposeDetector.from_pretrained("lllyasviel/Annotators")
-
-# prepare pose condition.
-url = "https://huggingface.co/Adapter/t2iadapter/resolve/main/people.jpg"
-image = load_image(url)
-image = open_pose(image, detect_resolution=512, image_resolution=1024)
-image = np.array(image)[:, :, ::-1]

-
-gen_images = pipe(
-  prompt=prompt,
-  control_image=image,
-  num_inference_steps=50,
-  guidance_scale=25., 
-).images[0]
-gen_images.save("output.png")
-```
-
-## Things to note
-
-* The scripts provided in this directory are experimental and educational. This means we may have to tweak things around to get good results on a given condition. We believe this is best done with the community 🤗
-* The scripts are not memory-optimized but we offload the VAE and the text encoders to CPU when they are not used if `--offload` is specified. 
-* We can extract LoRAs from the fully fine-tuned model. While we currently don't provide any utilities for that, users are welcome to refer to [this script](https://github.com/Stability-AI/stability-ComfyUI-nodes/blob/master/control_lora_create.py) that provides a similar functionality.

-[*Spatiotemporal Skip Guidance (STG) for Enhanced Video Diffusion Sampling*](https://arxiv.org/abs/2411.18664) (CVPR 2025) is a simple training-free sampling guidance method for enhancing transformer-based video diffusion models. STG employs an implicit weak model via self-perturbation, avoiding the need for external models or additional training. By selectively skipping spatiotemporal layers, STG produces an aligned, degraded version of the original model to boost sample quality without compromising diversity or dynamic degree.

-        Function invoked when calling the pipeline for generation.
-
-        Args:
-            prompt (`str` or `List[str]`, *optional*):
-                The prompt or prompts to guide the image generation. If not defined, one has to pass `prompt_embeds`.
-                instead.
-            negative_prompt (`str` or `List[str]`, *optional*):
-                The prompt or prompts not to guide the image generation. If not defined, one has to pass
-                `negative_prompt_embeds` instead. Ignored when not using guidance (i.e., ignored if `guidance_scale` is
-                less than `1`).
-            height (`int`, *optional*, defaults to self.transformer.config.sample_height * self.vae_scale_factor_spatial):
-                The height in pixels of the generated image. This is set to 480 by default for the best results.
-            width (`int`, *optional*, defaults to self.transformer.config.sample_height * self.vae_scale_factor_spatial):
-                The width in pixels of the generated image. This is set to 720 by default for the best results.
-            num_frames (`int`, defaults to `48`):
-                Number of frames to generate. Must be divisible by self.vae_scale_factor_temporal. Generated video will
-                contain 1 extra frame because CogVideoX is conditioned with (num_seconds * fps + 1) frames where
-                num_seconds is 6 and fps is 8. However, since videos can be saved at any fps, the only condition that
-                needs to be satisfied is that of divisibility mentioned above.
-            num_inference_steps (`int`, *optional*, defaults to 50):
-                The number of denoising steps. More denoising steps usually lead to a higher quality image at the
-                expense of slower inference.
-            timesteps (`List[int]`, *optional*):
-                Custom timesteps to use for the denoising process with schedulers which support a `timesteps` argument
-                in their `set_timesteps` method. If not defined, the default behavior when `num_inference_steps` is
-                passed will be used. Must be in descending order.
-            guidance_scale (`float`, *optional*, defaults to 7.0):
-                Guidance scale as defined in [Classifier-Free Diffusion Guidance](https://arxiv.org/abs/2207.12598).
-                `guidance_scale` is defined as `w` of equation 2. of [Imagen
-                Paper](https://arxiv.org/pdf/2205.11487.pdf). Guidance scale is enabled by setting `guidance_scale >
-                1`. Higher guidance scale encourages to generate images that are closely linked to the text `prompt`,
-                usually at the expense of lower image quality.
-            num_videos_per_prompt (`int`, *optional*, defaults to 1):
-                The number of videos to generate per prompt.
-            generator (`torch.Generator` or `List[torch.Generator]`, *optional*):
-                One or a list of [torch generator(s)](https://pytorch.org/docs/stable/generated/torch.Generator.html)
-                to make generation deterministic.
-            latents (`torch.FloatTensor`, *optional*):
-                Pre-generated noisy latents, sampled from a Gaussian distribution, to be used as inputs for image
-                generation. Can be used to tweak the same generation with different prompts. If not provided, a latents
-                tensor will ge generated by sampling using the supplied random `generator`.
-            prompt_embeds (`torch.FloatTensor`, *optional*):
-                Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. If not
-                provided, text embeddings will be generated from `prompt` input argument.
-            negative_prompt_embeds (`torch.FloatTensor`, *optional*):
-                Pre-generated negative text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt
-                weighting. If not provided, negative_prompt_embeds will be generated from `negative_prompt` input
-                argument.
-            output_type (`str`, *optional*, defaults to `"pil"`):
-                The output format of the generate image. Choose between
-                [PIL](https://pillow.readthedocs.io/en/stable/): `PIL.Image.Image` or `np.array`.
-            return_dict (`bool`, *optional*, defaults to `True`):
-                Whether or not to return a [`~pipelines.stable_diffusion_xl.StableDiffusionXLPipelineOutput`] instead
-                of a plain tuple.
-            attention_kwargs (`dict`, *optional*):
-                A kwargs dictionary that if specified is passed along to the `AttentionProcessor` as defined under
-                `self.processor` in
-                [diffusers.models.attention_processor](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py).
-            callback_on_step_end (`Callable`, *optional*):
-                A function that calls at the end of each denoising steps during the inference. The function is called
-                with the following arguments: `callback_on_step_end(self: DiffusionPipeline, step: int, timestep: int,
-                callback_kwargs: Dict)`. `callback_kwargs` will include a list of all tensors as specified by
-                `callback_on_step_end_tensor_inputs`.
-            callback_on_step_end_tensor_inputs (`List`, *optional*):
-                The list of tensor inputs for the `callback_on_step_end` function. The tensors specified in the list
-                will be passed as `callback_kwargs` argument. You will only be able to include variables listed in the
-                `._callback_tensor_inputs` attribute of your pipeline class.
-            max_sequence_length (`int`, defaults to `226`):
-                Maximum sequence length in encoded prompt. Must be consistent with
-                `self.transformer.config.max_text_seq_length` otherwise may lead to poor results.

-                The prompt or prompts to guide the image generation. If not defined, one has to pass `prompt_embeds`.
-                instead.
-            prompt_2 (`str` or `List[str]`, *optional*):
-                The prompt or prompts to be sent to `tokenizer_2` and `text_encoder_2`. If not defined, `prompt` is
-                will be used instead.
-            height (`int`, defaults to `720`):
-                The height in pixels of the generated image.
-            width (`int`, defaults to `1280`):
-                The width in pixels of the generated image.
-            num_frames (`int`, defaults to `129`):
-                The number of frames in the generated video.
-            num_inference_steps (`int`, defaults to `50`):
-                The number of denoising steps. More denoising steps usually lead to a higher quality image at the
-                expense of slower inference.
-            sigmas (`List[float]`, *optional*):
-                Custom sigmas to use for the denoising process with schedulers which support a `sigmas` argument in
-                their `set_timesteps` method. If not defined, the default behavior when `num_inference_steps` is passed
-                will be used.
-            guidance_scale (`float`, defaults to `6.0`):
-                Guidance scale as defined in [Classifier-Free Diffusion Guidance](https://arxiv.org/abs/2207.12598).
-                `guidance_scale` is defined as `w` of equation 2. of [Imagen
-                Paper](https://arxiv.org/pdf/2205.11487.pdf). Guidance scale is enabled by setting `guidance_scale >
-                1`. Higher guidance scale encourages to generate images that are closely linked to the text `prompt`,
-                usually at the expense of lower image quality. Note that the only available HunyuanVideo model is
-                CFG-distilled, which means that traditional guidance between unconditional and conditional latent is
-                not applied.
-            num_videos_per_prompt (`int`, *optional*, defaults to 1):
-                The number of images to generate per prompt.
-            generator (`torch.Generator` or `List[torch.Generator]`, *optional*):
-                A [`torch.Generator`](https://pytorch.org/docs/stable/generated/torch.Generator.html) to make
-                generation deterministic.
-            latents (`torch.Tensor`, *optional*):
-                Pre-generated noisy latents sampled from a Gaussian distribution, to be used as inputs for image
-                generation. Can be used to tweak the same generation with different prompts. If not provided, a latents
-                tensor is generated by sampling using the supplied random `generator`.
-            prompt_embeds (`torch.Tensor`, *optional*):
-                Pre-generated text embeddings. Can be used to easily tweak text inputs (prompt weighting). If not
-                provided, text embeddings are generated from the `prompt` input argument.
-            output_type (`str`, *optional*, defaults to `"pil"`):
-                The output format of the generated image. Choose between `PIL.Image` or `np.array`.
-            return_dict (`bool`, *optional*, defaults to `True`):
-                Whether or not to return a [`HunyuanVideoPipelineOutput`] instead of a plain tuple.
-            attention_kwargs (`dict`, *optional*):
-                A kwargs dictionary that if specified is passed along to the `AttentionProcessor` as defined under
-                `self.processor` in
-                [diffusers.models.attention_processor](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py).
-            clip_skip (`int`, *optional*):
-                Number of layers to be skipped from CLIP while computing the prompt embeddings. A value of 1 means that
-                the output of the pre-final layer will be used for computing the prompt embeddings.
-            callback_on_step_end (`Callable`, `PipelineCallback`, `MultiPipelineCallbacks`, *optional*):
-                A function or a subclass of `PipelineCallback` or `MultiPipelineCallbacks` that is called at the end of
-                each denoising step during the inference. with the following arguments: `callback_on_step_end(self:

-            callback_on_step_end_tensor_inputs (`List`, *optional*):
-                The list of tensor inputs for the `callback_on_step_end` function. The tensors specified in the list
-                will be passed as `callback_kwargs` argument. You will only be able to include variables listed in the

-            latents (`torch.Tensor`, *optional*):
-                Pre-generated noisy latents, sampled from a Gaussian distribution, to be used as inputs for image
-                generation. Can be used to tweak the same generation with different prompts. If not provided, a latents
-                tensor will ge generated by sampling using the supplied random `generator`.
-            prompt_embeds (`torch.Tensor`, *optional*):
-                Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. If not
-                provided, text embeddings will be generated from `prompt` input argument.
-            prompt_attention_mask (`torch.Tensor`, *optional*):
-                Pre-generated attention mask for text embeddings.
-            negative_prompt_embeds (`torch.FloatTensor`, *optional*):
-                Pre-generated negative text embeddings. For PixArt-Sigma this negative prompt should be "". If not
-                provided, negative_prompt_embeds will be generated from `negative_prompt` input argument.
-            negative_prompt_attention_mask (`torch.FloatTensor`, *optional*):
-                Pre-generated attention mask for negative text embeddings.
-            decode_timestep (`float`, defaults to `0.0`):
-                The timestep at which generated video is decoded.
-            decode_noise_scale (`float`, defaults to `None`):
-                The interpolation factor between random noise and denoised latents at the decode timestep.
-            output_type (`str`, *optional*, defaults to `"pil"`):
-                The output format of the generate image. Choose between
-                [PIL](https://pillow.readthedocs.io/en/stable/): `PIL.Image.Image` or `np.array`.
-            return_dict (`bool`, *optional*, defaults to `True`):
-                Whether or not to return a [`~pipelines.ltx.LTXPipelineOutput`] instead of a plain tuple.
-            attention_kwargs (`dict`, *optional*):
-                A kwargs dictionary that if specified is passed along to the `AttentionProcessor` as defined under
-                `self.processor` in
-                [diffusers.models.attention_processor](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py).
-            callback_on_step_end (`Callable`, *optional*):
-                A function that calls at the end of each denoising steps during the inference. The function is called
-                with the following arguments: `callback_on_step_end(self: DiffusionPipeline, step: int, timestep: int,
-                callback_kwargs: Dict)`. `callback_kwargs` will include a list of all tensors as specified by
-                `callback_on_step_end_tensor_inputs`.
-            callback_on_step_end_tensor_inputs (`List`, *optional*):
-                The list of tensor inputs for the `callback_on_step_end` function. The tensors specified in the list
-                will be passed as `callback_kwargs` argument. You will only be able to include variables listed in the
-                `._callback_tensor_inputs` attribute of your pipeline class.
-            max_sequence_length (`int` defaults to `128 `):
-                Maximum sequence length to use with the `prompt`.
-
-        Examples:
-
-        Returns:
-            [`~pipelines.ltx.LTXPipelineOutput`] or `tuple`:
-                If `return_dict` is `True`, [`~pipelines.ltx.LTXPipelineOutput`] is returned, otherwise a `tuple` is
-                returned where the first element is a list with the generated images.

-        Function invoked when calling the pipeline for generation.
-
-        Args:
-            image (`PipelineImageInput`):
-                The input image to condition the generation on. Must be an image, a list of images or a `torch.Tensor`.
-            prompt (`str` or `List[str]`, *optional*):
-                The prompt or prompts to guide the image generation. If not defined, one has to pass `prompt_embeds`.
-                instead.
-            height (`int`, defaults to `512`):
-                The height in pixels of the generated image. This is set to 480 by default for the best results.
-            width (`int`, defaults to `704`):
-                The width in pixels of the generated image. This is set to 848 by default for the best results.
-            num_frames (`int`, defaults to `161`):
-                The number of video frames to generate
-            num_inference_steps (`int`, *optional*, defaults to 50):
-                The number of denoising steps. More denoising steps usually lead to a higher quality image at the
-                expense of slower inference.
-            timesteps (`List[int]`, *optional*):
-                Custom timesteps to use for the denoising process with schedulers which support a `timesteps` argument
-                in their `set_timesteps` method. If not defined, the default behavior when `num_inference_steps` is
-                passed will be used. Must be in descending order.
-            guidance_scale (`float`, defaults to `3 `):
-                Guidance scale as defined in [Classifier-Free Diffusion Guidance](https://arxiv.org/abs/2207.12598).
-                `guidance_scale` is defined as `w` of equation 2. of [Imagen
-                Paper](https://arxiv.org/pdf/2205.11487.pdf). Guidance scale is enabled by setting `guidance_scale >
-                1`. Higher guidance scale encourages to generate images that are closely linked to the text `prompt`,
-                usually at the expense of lower image quality.
-            num_videos_per_prompt (`int`, *optional*, defaults to 1):
-                The number of videos to generate per prompt.
-            generator (`torch.Generator` or `List[torch.Generator]`, *optional*):
-                One or a list of [torch generator(s)](https://pytorch.org/docs/stable/generated/torch.Generator.html)
-                to make generation deterministic.
-            latents (`torch.Tensor`, *optional*):
-                Pre-generated noisy latents, sampled from a Gaussian distribution, to be used as inputs for image
-                generation. Can be used to tweak the same generation with different prompts. If not provided, a latents
-                tensor will ge generated by sampling using the supplied random `generator`.
-            prompt_embeds (`torch.Tensor`, *optional*):
-                Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. If not
-                provided, text embeddings will be generated from `prompt` input argument.
-            prompt_attention_mask (`torch.Tensor`, *optional*):
-                Pre-generated attention mask for text embeddings.
-            negative_prompt_embeds (`torch.FloatTensor`, *optional*):
-                Pre-generated negative text embeddings. For PixArt-Sigma this negative prompt should be "". If not
-                provided, negative_prompt_embeds will be generated from `negative_prompt` input argument.
-            negative_prompt_attention_mask (`torch.FloatTensor`, *optional*):
-                Pre-generated attention mask for negative text embeddings.
-            decode_timestep (`float`, defaults to `0.0`):
-                The timestep at which generated video is decoded.
-            decode_noise_scale (`float`, defaults to `None`):
-                The interpolation factor between random noise and denoised latents at the decode timestep.
-            output_type (`str`, *optional*, defaults to `"pil"`):
-                The output format of the generate image. Choose between
-                [PIL](https://pillow.readthedocs.io/en/stable/): `PIL.Image.Image` or `np.array`.
-            return_dict (`bool`, *optional*, defaults to `True`):
-                Whether or not to return a [`~pipelines.ltx.LTXPipelineOutput`] instead of a plain tuple.
-            attention_kwargs (`dict`, *optional*):
-                A kwargs dictionary that if specified is passed along to the `AttentionProcessor` as defined under
-                `self.processor` in
-                [diffusers.models.attention_processor](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py).
-            callback_on_step_end (`Callable`, *optional*):
-                A function that calls at the end of each denoising steps during the inference. The function is called
-                with the following arguments: `callback_on_step_end(self: DiffusionPipeline, step: int, timestep: int,
-                callback_kwargs: Dict)`. `callback_kwargs` will include a list of all tensors as specified by
-                `callback_on_step_end_tensor_inputs`.
-            callback_on_step_end_tensor_inputs (`List`, *optional*):
-                The list of tensor inputs for the `callback_on_step_end` function. The tensors specified in the list
-                will be passed as `callback_kwargs` argument. You will only be able to include variables listed in the
-                `._callback_tensor_inputs` attribute of your pipeline class.
-            max_sequence_length (`int` defaults to `128 `):
-                Maximum sequence length to use with the `prompt`.
-
-        Examples:
-
-        Returns:

-                Paper](https://arxiv.org/pdf/2205.11487.pdf). Guidance scale is enabled by setting `guidance_scale >
-                1`. Higher guidance scale encourages to generate images that are closely linked to the text `prompt`,
-                usually at the expense of lower image quality.
-            num_videos_per_prompt (`int`, *optional*, defaults to 1):
-                The number of videos to generate per prompt.
-            generator (`torch.Generator` or `List[torch.Generator]`, *optional*):
-                One or a list of [torch generator(s)](https://pytorch.org/docs/stable/generated/torch.Generator.html)
-                to make generation deterministic.
-            latents (`torch.Tensor`, *optional*):
-                Pre-generated noisy latents, sampled from a Gaussian distribution, to be used as inputs for image
-                generation. Can be used to tweak the same generation with different prompts. If not provided, a latents
-                tensor will ge generated by sampling using the supplied random `generator`.
-            prompt_embeds (`torch.Tensor`, *optional*):
-                Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. If not
-                provided, text embeddings will be generated from `prompt` input argument.
-            prompt_attention_mask (`torch.Tensor`, *optional*):
-                Pre-generated attention mask for text embeddings.
-            negative_prompt_embeds (`torch.FloatTensor`, *optional*):
-                Pre-generated negative text embeddings. For PixArt-Sigma this negative prompt should be "". If not
-                provided, negative_prompt_embeds will be generated from `negative_prompt` input argument.
-            negative_prompt_attention_mask (`torch.FloatTensor`, *optional*):
-                Pre-generated attention mask for negative text embeddings.
-            output_type (`str`, *optional*, defaults to `"pil"`):
-                The output format of the generate image. Choose between
-                [PIL](https://pillow.readthedocs.io/en/stable/): `PIL.Image.Image` or `np.array`.
-            return_dict (`bool`, *optional*, defaults to `True`):
-                Whether or not to return a [`~pipelines.mochi.MochiPipelineOutput`] instead of a plain tuple.
-            attention_kwargs (`dict`, *optional*):
-                A kwargs dictionary that if specified is passed along to the `AttentionProcessor` as defined under
-                `self.processor` in
-                [diffusers.models.attention_processor](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py).
-            callback_on_step_end (`Callable`, *optional*):
-                A function that calls at the end of each denoising steps during the inference. The function is called
-                with the following arguments: `callback_on_step_end(self: DiffusionPipeline, step: int, timestep: int,
-                callback_kwargs: Dict)`. `callback_kwargs` will include a list of all tensors as specified by
-                `callback_on_step_end_tensor_inputs`.
-            callback_on_step_end_tensor_inputs (`List`, *optional*):
-                The list of tensor inputs for the `callback_on_step_end` function. The tensors specified in the list
-                will be passed as `callback_kwargs` argument. You will only be able to include variables listed in the
-                `._callback_tensor_inputs` attribute of your pipeline class.
-            max_sequence_length (`int` defaults to `256`):
-                Maximum sequence length to use with the `prompt`.
-
-        Examples:
-
-        Returns:
-            [`~pipelines.mochi.MochiPipelineOutput`] or `tuple`:
-                If `return_dict` is `True`, [`~pipelines.mochi.MochiPipelineOutput`] is returned, otherwise a `tuple`
-                is returned where the first element is a list with the generated images.

-"AnyText comprises a diffusion pipeline with two primary elements: an auxiliary latent module and a text embedding module. The former uses inputs like text glyph, position, and masked image to generate latent features for text generation or editing. The latter employs an OCR model for encoding stroke data as embeddings, which blend with image caption embeddings from the tokenizer to generate texts that seamlessly integrate with the background. We employed text-control diffusion loss and text perceptual loss for training to further enhance writing accuracy."

-                The noisy input tensor.
-            timestep (`Union[torch.Tensor, float, int]`):
-                The number of timesteps to denoise an input.
-            encoder_hidden_states (`torch.Tensor`):
-                The encoder hidden states.
-            #controlnet_cond (`torch.Tensor`):
-            #    The conditional input tensor of shape `(batch_size, sequence_length, hidden_size)`.
-            conditioning_scale (`float`, defaults to `1.0`):
-                The scale factor for ControlNet outputs.
-            class_labels (`torch.Tensor`, *optional*, defaults to `None`):
-                Optional class labels for conditioning. Their embeddings will be summed with the timestep embeddings.
-            timestep_cond (`torch.Tensor`, *optional*, defaults to `None`):
-                Additional conditional embeddings for timestep. If provided, the embeddings will be summed with the
-                timestep_embedding passed through the `self.time_embedding` layer to obtain the final timestep
-                embeddings.
-            attention_mask (`torch.Tensor`, *optional*, defaults to `None`):
-                An attention mask of shape `(batch, key_tokens)` is applied to `encoder_hidden_states`. If `1` the mask
-                is kept, otherwise if `0` it is discarded. Mask will be converted into a bias, which adds large
-                negative values to the attention scores corresponding to "discard" tokens.
-            added_cond_kwargs (`dict`):
-                Additional conditions for the Stable Diffusion XL UNet.
-            cross_attention_kwargs (`dict[str]`, *optional*, defaults to `None`):
-                A kwargs dictionary that if specified is passed along to the `AttnProcessor`.
-            guess_mode (`bool`, defaults to `False`):
-                In this mode, the ControlNet encoder tries its best to recognize the input content of the input even if
-                you remove all prompts. A `guidance_scale` between 3.0 and 5.0 is recommended.
-            return_dict (`bool`, defaults to `True`):
-                Whether or not to return a [`~models.controlnet.ControlNetOutput`] instead of a plain tuple.
-
-        Returns:
-            [`~models.controlnet.ControlNetOutput`] **or** `tuple`:
-                If `return_dict` is `True`, a [`~models.controlnet.ControlNetOutput`] is returned, otherwise a tuple is
-                returned where the first element is the sample tensor.
