# Joint magnitude pruning, quantization and distillation on BERT-base/SST-2

This model conducts unstructured magnitude pruning, quantization and distillation at the same time on BERT-base when finetuning on the GLUE SST2 dataset.
It achieves the following results on the evaluation set:
- Torch loss: 0.3858
- Torch accuracy: 0.9128
- OpenVINO IR accuracy: 0.9128
- Sparsity in transformer block linear layers: 0.80

## Setup

```
conda install pytorch torchvision torchaudio pytorch-cuda=11.6 -c pytorch -c nvidia
git clone https://github.com/yujiepan-work/optimum-intel.git
git checkout -b "magnitude-pruning" 01927af543eaea8678671bf8f4eb78fdb29f8930
cd optimum-intel
pip install -e .[openvino,nncf]

cd examples/openvino/text-classification/
pip install -r requirements.txt
pip install wandb # optional
```

## NNCF config

See `nncf_config.json` in this repo.


## Run

We use one card for training.

```

The best model checkpoint is stored in the `best_model` folder. Here we only upload that checkpoint folder together with some config files.
