# INT8 roberta-base-mrpc |
|
|
|
### Post-training static quantization |
|
|
|
This is an INT8 PyTorch model quantized with [Intel® Neural Compressor](https://github.com/intel/neural-compressor). |
|
|
|
The original fp32 model comes from the fine-tuned model [roberta-base-mrpc](https://huggingface.co/Intel/roberta-base-mrpc). |
|
|
|
The calibration dataloader is the train dataloader. The default calibration sampling size 300 isn't divisible exactly by batch size 8, so the real sampling size is 304. |
|
|
|
Embedding module **roberta.embeddings.token_type_embeddings** is fallbacked to fp32 due to *Unexpected exception RuntimeError('Expect weight, indices, and offsets to be contiguous.')* |
|
|
|
### 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)** |25.737|13.171| |
|
| **Accuracy (eval-f1)** |0.9247|0.9138| |
|
| **Model size (MB)** |121|476| |
|
|
|
### Load with Intel® Neural Compressor (build from source): |
|
|
|
```python |
|
from neural_compressor.utils.load_huggingface import OptimizedModel |
|
int8_model = OptimizedModel.from_pretrained( |
|
'Intel/roberta-base-mrpc-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. |
