[CogVideoX: Text-to-Video Diffusion Models with An Expert Transformer](https://arxiv.org/abs/2408.06072) from Tsinghua University & ZhipuAI, by Zhuoyi Yang, Jiayan Teng, Wendi Zheng, Ming Ding, Shiyu Huang, Jiazheng Xu, Yuanming Yang, Wenyi Hong, Xiaohan Zhang, Guanyu Feng, Da Yin, Xiaotao Gu, Yuxuan Zhang, Weihan Wang, Yean Cheng, Ting Liu, Bin Xu, Yuxiao Dong, Jie Tang.
[TODO]() from Tsinghua University & ZhipuAI.
The abstract from the paper is:
*We introduce CogVideoX, a large-scale diffusion transformer model designed for generating videos based on text prompts. To efficently model video data, we propose to levearge a 3D Variational Autoencoder (VAE) to compresses videos along both spatial and temporal dimensions. To improve the text-video alignment, we propose an expert transformer with the expert adaptive LayerNorm to facilitate the deep fusion between the two modalities. By employing a progressive training technique, CogVideoX is adept at producing coherent, long-duration videos characterized by significant motion. In addition, we develop an effectively text-video data processing pipeline that includes various data preprocessing strategies and a video captioning method. It significantly helps enhance the performance of CogVideoX, improving both generation quality and semantic alignment. Results show that CogVideoX demonstrates state-of-the-art performance across both multiple machine metrics and human evaluations. The model weight of CogVideoX-2B is publicly available at https://github.com/THUDM/CogVideo.*

The panda's fluffy paws strum a miniature acoustic guitar, producing soft, melodic tunes. Nearby, a few other pandas gather, watching curiously and some clapping in rhythm. Sunlight filters through the tall bamboo, casting a gentle glow on the scene. The panda's face is expressive, showing concentration and joy as it plays. The background includes a small, flowing stream and vibrant green foliage, enhancing the peaceful and magical atmosphere of this unique musical performance."

### Memory optimization
CogVideoX-2b requires about 19 GB of GPU memory to decode 49 frames (6 seconds of video at 8 FPS) with output resolution 720x480 (W x H), which makes it not possible to run on consumer GPUs or free-tier T4 Colab. The following memory optimizations could be used to reduce the memory footprint. For replication, you can refer to [this](https://gist.github.com/a-r-r-o-w/3959a03f15be5c9bd1fe545b09dfcc93) script.

## 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.
FP16 inference code:
```python
import torch
from diffusers import FluxPipeline
pipe = FluxPipeline.from_pretrained("black-forest-labs/FLUX.1-schnell", torch_dtype=torch.bfloat16) # can replace schnell with dev
# to run on low vram GPUs (i.e. between 4 and 32 GB VRAM)
pipe.enable_sequential_cpu_offload()
pipe.vae.enable_slicing()
pipe.vae.enable_tiling()
pipe.to(torch.float16) # casting here instead of in the pipeline constructor because doing so in the constructor loads all models into CPU memory at once
prompt = "A cat holding a sign that says hello world"
out = pipe(
prompt=prompt,
guidance_scale=0.,
height=768,
width=1360,
num_inference_steps=4,
max_sequence_length=256,
).images[0]
out.save("image.png")
```
## Single File Loading for the `FluxTransformer2DModel`
The `FluxTransformer2DModel` supports loading checkpoints in the original format shipped by Black Forest Labs. This is also useful when trying to load finetunes or quantized versions of the models that have been published by the community.
<Tip>
`FP8` inference can be brittle depending on the GPU type, CUDA version, and `torch` version that you are using. It is recommended that you use the `optimum-quanto` library in order to run FP8 inference on your machine.
</Tip>
The following example demonstrates how to run Flux with less than 16GB of VRAM.
First install `optimum-quanto`
```shell
pip install optimum-quanto
```
Then run the following example
```python
import torch
from diffusers import FluxTransformer2DModel, FluxPipeline
from transformers import T5EncoderModel, CLIPTextModel
from optimum.quanto import freeze, qfloat8, quantize
bfl_repo = "black-forest-labs/FLUX.1-dev"
dtype = torch.bfloat16
transformer = FluxTransformer2DModel.from_single_file("https://huggingface.co/Kijai/flux-fp8/blob/main/flux1-dev-fp8.safetensors", torch_dtype=dtype)
quantize(transformer, weights=qfloat8)
freeze(transformer)
text_encoder_2 = T5EncoderModel.from_pretrained(bfl_repo, subfolder="text_encoder_2", torch_dtype=dtype)
quantize(text_encoder_2, weights=qfloat8)
freeze(text_encoder_2)
pipe = FluxPipeline.from_pretrained(bfl_repo, transformer=None, text_encoder_2=None, torch_dtype=dtype)
pipe.transformer = transformer
pipe.text_encoder_2 = text_encoder_2
pipe.enable_model_cpu_offload()

image = pipe(
prompt,

output_type="pil",
num_inference_steps=20,
generator=torch.Generator("cpu").manual_seed(0)

# Pipeline callbacks
The denoising loop of a pipeline can be modified with custom defined functions using the `callback_on_step_end` parameter. The callback function is executed at the end of each step, and modifies the pipeline attributes and variables for the next step. This is really useful for *dynamically* adjusting certain pipeline attributes or modifying tensor variables. This versatility allows for interesting use cases such as changing the prompt embeddings at each timestep, assigning different weights to the prompt embeddings, and editing the guidance scale. With callbacks, you can implement new features without modifying the underlying code!

"""
A Transformer model for video-like data in [CogVideoX](https://github.com/THUDM/CogVideo).
A Transformer model for video-like data in CogVideoX. TODO: add link to CogVideoX upon release
Parameters:
num_attention_heads (`int`, defaults to `30`):
The number of heads to use for multi-head attention.
attention_head_dim (`int`, defaults to `64`):
The number of channels in each head.
in_channels (`int`, defaults to `16`):
num_attention_heads (`int`, *optional*, defaults to 16): The number of heads to use for multi-head attention.
attention_head_dim (`int`, *optional*, defaults to 88): The number of channels in each head.
in_channels (`int`, *optional*):
The number of channels in the input.
out_channels (`int`, *optional*, defaults to `16`):
out_channels (`int`, *optional*):
The number of channels in the output.
flip_sin_to_cos (`bool`, defaults to `True`):
Whether to flip the sin to cos in the time embedding.
time_embed_dim (`int`, defaults to `512`):
Output dimension of timestep embeddings.
text_embed_dim (`int`, defaults to `4096`):
Input dimension of text embeddings from the text encoder.
num_layers (`int`, defaults to `30`):
The number of layers of Transformer blocks to use.
dropout (`float`, defaults to `0.0`):
The dropout probability to use.
attention_bias (`bool`, defaults to `True`):
Whether or not to use bias in the attention projection layers.
sample_width (`int`, defaults to `90`):
The width of the input latents.
sample_height (`int`, defaults to `60`):
The height of the input latents.
sample_frames (`int`, defaults to `49`):
The number of frames in the input latents. Note that this parameter was incorrectly initialized to 49
instead of 13 because CogVideoX processed 13 latent frames at once in its default and recommended settings,
but cannot be changed to the correct value to ensure backwards compatibility. To create a transformer with
K latent frames, the correct value to pass here would be: ((K - 1) * temporal_compression_ratio + 1).
patch_size (`int`, defaults to `2`):
num_layers (`int`, *optional*, defaults to 1): The number of layers of Transformer blocks to use.
dropout (`float`, *optional*, defaults to 0.0): The dropout probability to use.
cross_attention_dim (`int`, *optional*): The number of `encoder_hidden_states` dimensions to use.
attention_bias (`bool`, *optional*):
Configure if the `TransformerBlocks` attention should contain a bias parameter.
sample_size (`int`, *optional*): The width of the latent images (specify if the input is **discrete**).
This is fixed during training since it is used to learn a number of position embeddings.
patch_size (`int`, *optional*):
The size of the patches to use in the patch embedding layer.
temporal_compression_ratio (`int`, defaults to `4`):
The compression ratio across the temporal dimension. See documentation for `sample_frames`.
max_text_seq_length (`int`, defaults to `226`):
The maximum sequence length of the input text embeddings.
activation_fn (`str`, defaults to `"gelu-approximate"`):
Activation function to use in feed-forward.
timestep_activation_fn (`str`, defaults to `"silu"`):
Activation function to use when generating the timestep embeddings.
norm_elementwise_affine (`bool`, defaults to `True`):
activation_fn (`str`, *optional*, defaults to `"geglu"`): Activation function to use in feed-forward.
num_embeds_ada_norm ( `int`, *optional*):
The number of diffusion steps used during training. Pass if at least one of the norm_layers is
`AdaLayerNorm`. This is fixed during training since it is used to learn a number of embeddings that are
added to the hidden states. During inference, you can denoise for up to but not more steps than
`num_embeds_ada_norm`.
norm_type (`str`, *optional*, defaults to `"layer_norm"`):
The type of normalization to use. Options are `"layer_norm"` or `"ada_layer_norm"`.
norm_elementwise_affine (`bool`, *optional*, defaults to `True`):
Whether or not to use elementwise affine in normalization layers.
norm_eps (`float`, defaults to `1e-5`):
The epsilon value to use in normalization layers.
spatial_interpolation_scale (`float`, defaults to `1.875`):
Scaling factor to apply in 3D positional embeddings across spatial dimensions.
temporal_interpolation_scale (`float`, defaults to `1.0`):
Scaling factor to apply in 3D positional embeddings across temporal dimensions.
norm_eps (`float`, *optional*, defaults to 1e-5): The epsilon value to use in normalization layers.
caption_channels (`int`, *optional*):
The number of channels in the caption embeddings.
video_length (`int`, *optional*):
The number of frames in the video-like data.
