  # INT8 roberta-base-mrpc
  
  ##  Post-training static quantization
  
  ### PyTorch
  
  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 100 isn't divisible exactly by batch size 8, so the real sampling size is 104.
  
  #### Test result
  
  |   |INT8|FP32|
  |---|:---:|:---:|
  | **Accuracy (eval-f1)** |0.9177|0.9138|
  | **Model size (MB)**  |127|499|
  
  #### Load with Intel® Neural Compressor:
  
  ```python
  from optimum.intel.neural_compressor import IncQuantizedModelForSequenceClassification
  
  model_id = "Intel/roberta-base-mrpc-int8-static"
  int8_model = IncQuantizedModelForSequenceClassification.from_pretrained(model_id)
  ```
  
  ### ONNX
  
  This is an INT8 ONNX 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).
  
  #### Test result
  
  |   |INT8|FP32|
  |---|:---:|:---:|
  | **Accuracy (eval-f1)** |0.9073|0.9138|
  | **Model size (MB)**  |243|476|
  
  
  #### Load ONNX model:
  
  ```python
  from optimum.onnxruntime import ORTModelForSequenceClassification
  model = ORTModelForSequenceClassification.from_pretrained('Intel/roberta-base-mrpc-int8-static')
  ```
