[gpt2](https://huggingface.co/openai-community/gpt2) quantized to 4-bit using [AutoGPTQ](https://github.com/AutoGPTQ/AutoGPTQ). |
|
|
|
To use, first install AutoGPTQ: |
|
|
|
```shell |
|
pip install auto-gptq |
|
``` |
|
|
|
Then load the model from the hub: |
|
```python |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
from auto_gptq import AutoGPTQForCausalLM, BaseQuantizeConfig |
|
|
|
model_name = "smpanaro/gpt2-AutoGPTQ-4bit-128g" |
|
model = AutoGPTQForCausalLM.from_quantized(model_name) |
|
``` |
