# 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. |

|---|:---:|:---:| |
|
| **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. |
