This is a quantized version of [DistilGPT2](https://huggingface.co/distilbert/distilgpt2). We provide the following two quantization configurations:

BASELINE: Everything in original format, equivalent to original model.

FALLBACK: Quantized Linear and Conv1D layers to BFP16. Added approximation functions for Layer Norm, GELU and Softmax.

### Usage Example

Prerequisites:
- Install dmx-mltools: "pip install dmx-mltools"
- clone this repo. "cd" to the cloned repo.
```python
>>> import os
>>> from mltools import dmx
>>> from transformers import pipeline
>>> import evaluate
>>> from datasets import load_dataset

>>> my_hf_token = os.environ.get("HUGGING_FACE_HUB_TOKEN")

>>> pipe = pipeline(
>>>     "text-generation",
>>>     model="d-matrix/distilgpt2",
>>>     use_auth_token=my_hf_token,
>>>     trust_remote_code=True,
>>>     # device_map="auto", # use this line for enabling pipeline parallel
>>> )
>>> pipe.model = dmx.Model(
>>>     pipe.model, monkey_patched=False, hf=True, input_names=["input_ids", "labels"]
>>> )

>>> pipe.model.transform("FALLBACK.yaml")

>>> perplexity = evaluate.load("d-matrix/dmx_perplexity", module_type="metric")
>>> input_texts = load_dataset("ptb_text_only", "penn_treebank", split="test")["sentence"]
>>> results = perplexity.compute(model=pipe.model.body, references=input_texts)
>>> print(results)
{'loss': 4.164604187011719, 'perplexity': 64.36720275878906}
