# INT8 DistilBERT base uncased finetuned SST-2
### Post-training static quantization
This is an INT8 PyTorch model quantified with [intel/nlp-toolkit](https://github.com/intel/nlp-toolkit) using provider: [Intel® Neural Compressor](https://github.com/intel/neural-compressor).
The original fp32 model comes from the fine-tuned model [distilbert-base-uncased-finetuned-sst-2-english](https://huggingface.co/distilbert-base-uncased-finetuned-sst-2-english).
The calibration dataloader is the train dataloader. The default calibration sampling size 100 isn't divisible exactly by batch size 8, so
the real sampling size is 104.
### Test result
- Batch size = 8
- [Amazon Web Services](https://aws.amazon.com/) c6i.xlarge (Intel ICE Lake: 4 vCPUs, 8g Memory) instance.
| |INT8|FP32|
|---|:---:|:---:|
| **Throughput (samples/sec)** |47.554|23.046|
| **Accuracy (eval-accuracy)** |0.9037|0.9106|
| **Model size (MB)** |65|255|
### Load with nlp-toolkit:
```python
from nlp_toolkit import OptimizedModel
int8_model = OptimizedModel.from_pretrained(
'Intel/distilbert-base-uncased-finetuned-sst-2-english-int8-static',
)
```
Notes:
- The INT8 model has better performance than the FP32 model when the CPU is fully occupied. Otherwise, there will be the illusion that INT8 is inferior to FP32.
