# INT8 DistilBart finetuned on CNN DailyMail

### Post-training dynamic quantization

This is an INT8  PyTorch model quantized with [huggingface/optimum-intel](https://github.com/huggingface/optimum-intel) through the usage of [Intel® Neural Compressor](https://github.com/intel/neural-compressor). 

The original fp32 model comes from the fine-tuned model [facebook/bart-large-cnn](https://huggingface.co/facebook/bart-large-cnn).

Below linear modules (40/193) are fallbacked to fp32 for less than 1% relative accuracy loss:

**'model.decoder.layers.10.fc1'**, **'model.decoder.layers.0.fc2'**, 
**'model.decoder.layers.4.fc2'**, **'model.decoder.layers.1.fc2'**, 
**'model.decoder.layers.6.fc2'**, **'model.decoder.layers.2.fc2'**, 
**'model.decoder.layers.3.fc2'**, **'model.encoder.layers.11.fc2'**, 
**'model.decoder.layers.9.fc1'**, **'model.decoder.layers.5.fc2'**, 
**'model.decoder.layers.7.fc1'**, **'model.decoder.layers.8.fc1'**, 
**'model.encoder.layers.0.fc2'**, **'model.decoder.layers.11.fc1'**, 
**'model.encoder.layers.8.fc2'**, **'model.encoder.layers.11.fc1'**, 
**'model.decoder.layers.8.fc2'**, **'model.decoder.layers.2.fc1'**,

**'model.decoder.layers.9.fc2'**, **'model.decoder.layers.7.fc2'**,
