## Support Matrix
* FP32/FP16/BF16/INT8 Weight-Only/INT4 Weight-Only/SmoothQuant/FP8
* For SmoothQuant, TRT-LLM only supports FP16 higher precision now.
* checkpoint type: Jax, Torch, Keras, Huggingface (HF)
* STRONGLY TYPED
* python runtime and triton backend
## Common scripts
### Convert checkpoint
Please install required packages first:
```bash
pip install -r requirements.txt
```
Users can use `convert_checkpoint.py` to convert the different source checkpoint to unified TensorRT-LLM checkpoint format. Users could set `--dtype` to determine the inference data type, and set the quantization options like `--enable_fp8`, `--fp8_kv_cache` `--use_smooth_quant`, `--calibrate_kv_cache` (for INT8 kv cache) and `--use-weight-only-with-precision` (weight only). Users could also control the source checkpoint type by `--ckpt-type`. Currently, supported checkpoint types are `jax`, `torch` and `keras`.
```bash
CKPT_PATH=/tmp/models/gemma_nv/checkpoints/tmp_2b_it
UNIFIED_CKPT_PATH=/tmp/checkpoints/tmp_2b_it_tensorrt_llm/bf16/tp1/
python3 ./convert_checkpoint.py \
--ckpt-type jax \
--model-dir ${CKPT_PATH} \
--dtype bfloat16 \
--world-size 1 \
--output-model-dir ${UNIFIED_CKPT_PATH}
```
### Build engine
After getting checkpoint, we can use `trtllm-build` command to build TensorRT-LLM engines from TensorRT-LLM checkpoints.
```bash
ENGINE_PATH=/tmp/gemma/2B/bf16/1-gpu/
trtllm-build --checkpoint_dir ${UNIFIED_CKPT_PATH} \
--gemm_plugin bfloat16 \
--gpt_attention_plugin bfloat16 \
--max_batch_size 8 \
--max_input_len 3000 \
--max_output_len 100 \
--lookup_plugin bfloat16 \
--output_dir ${ENGINE_PATH}
```
### Run inference
We provide three examples to run inference `run.py`, `summarize.py` and `mmlu.py`. `run.py` only run inference with `input_text` and show the output.
`summarize.py` runs summarization on [cnn_dailymail](https://huggingface.co/datasets/cnn_dailymail) dataset and evaluate the model by [ROUGE](https://en.wikipedia.org/wiki/ROUGE_(metric)) scores and use the `ROUGE-1` score to validate the implementation.
`mmlu.py` runs MMLU to evaluate the model by accuracy.
Note that we need to download the dataset of MMLU first and the evaluation of MMLU requires more time.

## Specific commands
In this section, we demonstrate the scripts to convert checkpoint, building engine and run inference on different settings. We will not demonstrate all combinations here because there are too many cases. We choose some important cases to demonstrate.

#### Run inference under FP8 for keras checkpoint
WARNING: This way of running FP8 will introduce noticeable accuracy drop. To avoid that, use Modelopt quantization mentioned in this readme.
In this example, we demonstrate how to run FP8 inference on Gemma. Note that `convert_checkpoint.py` only uses identity activation scales, so the accuracy might be little worse than higher precision in some cases, but it is still very good because we don't do any calibration. This also shows the stability of FP8 compared to INT8.

#### Run inference under FP8 for jax checkpoint
WARNING: This way of running FP8 will introduce noticeable accuracy drop. To avoid that, use Modelopt quantization mentioned in this readme.
In this example, we demonstrate how to run FP8 inference on Gemma. Note that `convert_checkpoint.py` only uses identity activation scales, so the accuracy might be little worse than higher precision in some cases, but it is still very good because we don't do any calibration. This also shows the stability of FP8 compared to INT8.

### Run Modelopt Quantization
#### Requirements
Modelopt toolkit also provides quantization solutions. To enable it, have the latest modelopt and transformers Python package installed to support Gemma. Then run the following commands.
#### Quantize Checkpoints
```
python ../quantization/quantize.py --model_dir ${HF_GEMMA_PATH} \
--dtype float16 \
--qformat ${QUANT_TYPE} \
--output_dir ${UNIFIED_CKPT_PATH} \
--tp_size 1
```
HF_GEMMA_PATH can either be HF model card name or the downloaded model path. QUANT_TYPE can be chosen from fp8, int4_awq, and int8_sq.
#### Build Engines
For fp8, build engines with:
```
trtllm-build --checkpoint_dir ${UNIFIED_CKPT_PATH} \
--gemm_plugin float16 \
--gpt_attention_plugin float16 \
--max_batch_size 8 \
--max_input_len 3000 \
--max_output_len 100 \
--lookup_plugin float16 \
--output_dir ${ENGINE_PATH}
```
For int4_awq and int8_sq, build engines with:
```
trtllm-build --checkpoint_dir ${UNIFIED_CKPT_PATH} \
--gemm_plugin float16 \
--gpt_attention_plugin float16 \
--max_batch_size 8 \
--max_input_len 3000 \
--max_output_len 100 \
--enable_xqa enable \
--lookup_plugin float16 \
--output_dir ${ENGINE_PATH}
```
#### Accuracy Results on MMLU
| Model | fp8 | int4_awq | int8_sq (Modelopt) | int8_sq (Native per-channel) |
|---------------|-------|----------|----------------|------------------|
| 2B Pretrained | 0.407 | 0.378 | 0.338 | 0.338 |
| 7B Pretrained | 0.643 | 0.615 | 0.448 | 0.595 |
