# FBGEMM FP8
|
|
|
|
With FBGEMM FP8 quantization method, you can quantize your model in FP8 (W8A8):
|
|
- the weights will be quantized in 8bit (FP8) per channel
|
|
- the activation will be quantized in 8bit (FP8) per token
|
|
|
|
It relies on the [FBGEMM](https://github.com/pytorch/FBGEMM) library which provides efficient low-precision general matrix multiplication for small batch sizes and support for accuracy-loss minimizing techniques such as row-wise quantization and outlier-aware quantization.
|
|
|
|
> [!TIP]
|
|
> You need a GPU with compute capability>=9 (e.g. H100)
|
|
|
|
Before you begin, make sure the following libraries are installed with their latest version:
|
|
|
|
```bash
|
|
pip install --upgrade accelerate fbgemm-gpu torch
|
|
```
|
|
|
|
If you are having issues with fbgemm-gpu and torch library, you might need to install the nightly release. You can follow the instruction [here](https://pytorch.org/FBGEMM/fbgemm_gpu-development/InstallationInstructions.html#fbgemm-gpu-install-libraries:~:text=found%20here.-,Install%20the%20FBGEMM_GPU%20Package,-Install%20through%20PyTorch)
|
|
|
|
|
|
```py
|
|
from transformers import FbgemmFp8Config, AutoModelForCausalLM, AutoTokenizer
|
|
|
|
model_name = "meta-llama/Meta-Llama-3-8B"
|
|
quantization_config = FbgemmFp8Config()
|
|
quantized_model = AutoModelForCausalLM.from_pretrained(model_name, device_map="auto", quantization_config=quantization_config)
|
|
|
|
tokenizer = AutoTokenizer.from_pretrained(model_name)
|
|
input_text = "What are we having for dinner?"
|
|
input_ids = tokenizer(input_text, return_tensors="pt").to("cuda")
|
|
|
|
output = quantized_model.generate(**input_ids, max_new_tokens=10)
|
|
print(tokenizer.decode(output[0], skip_special_tokens=True))
|
|
```
|
|
|
|
A quantized model can be saved via "saved_pretrained" and be reused again via the "from_pretrained".
|
|
|
|
```py
|
|
quant_path = "/path/to/save/quantized/model"
|
|
model.save_pretrained(quant_path)
|
|
model = AutoModelForCausalLM.from_pretrained(quant_path, device_map="auto")
|
|
``` |
