The INT8 model based on vit-base-patch16-224 which finetuned on imagenet-1k
Post-training static quantization
This is an INT8 PyTorch model quantized with Intel® Neural Compressor.
The original fp32 model comes from the fine-tuned model google/vit-base-patch16-224.
The calibration dataloader is the train dataloader. The default calibration sampling size 1000 because of 1000 classes of imagenet-1k.
The linear modules vit.encoder.layer.5.output.dense, vit.encoder.layer.9.attention.attention.query.module, fall back to fp32 for less than 1% relative accuracy loss.
Evaluation result
| INT8 | FP32 | |
