# INT8 bert-base-uncased-finetuned-swag

### Post-training static quantization
|
30 |
+
|
31 |
+
This is an INT8 PyTorch model quantized with [Intel® Neural Compressor](https://github.com/intel/neural-compressor).
|
32 |
+
|
33 |
+
The original fp32 model comes from the fine-tuned model [thyagosme/bert-base-uncased-finetuned-swag](https://huggingface.co/thyagosme/bert-base-uncased-finetuned-swag).
|
34 |
+
|
35 |
+
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.
|
36 |
+
|
37 |
+
### Test result
|
38 |
+
|
39 |
+
- Batch size = 8
|
40 |
+
- [Amazon Web Services](https://aws.amazon.com/) c6i.xlarge (Intel ICE Lake: 4 vCPUs, 8g Memory) instance.

### Load with Intel® Neural Compressor (build from source):
|

+
|
50 |
+
```python
|
51 |
+
from neural_compressor.utils.load_huggingface import OptimizedModel
|
52 |
+
int8_model = OptimizedModel.from_pretrained(
|
53 |
+
'Intel/bert-base-uncased-finetuned-swag-int8-static',
|
54 |
+
)
|
55 |
+
```
|
56 |
+
|
57 |
+
Notes:
|
58 |
+
- 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.
