INT8 BERT base uncased finetuned MRPC

Post-training static quantization

This is an INT8 PyTorch model quantized with huggingface/optimum-intel through the usage of Intel® Neural Compressor.

The original fp32 model comes from the fine-tuned model Intel/bert-base-uncased-mrpc.

The calibration dataloader is the train dataloader. The calibration sampling size is 1000.

The linear module bert.encoder.layer.9.output.dense falls back to fp32 to meet the 1% relative accuracy loss.

Test result

	INT8	FP32
Accuracy (eval-f1)	0.8959	0.9042
Model size (MB)	119	418

Load with Intel® Neural Compressor:

from optimum.intel.neural_compressor import IncQuantizedModelForSequenceClassification
int8_model = IncQuantizedModelForSequenceClassification.from_pretrained(
