Description

🚀 The feature

hi, thanks for your great work. I hope to be able to add quantized vit model (for ptq or qat).

Motivation, pitch

In 'torchvision/models/quantization', there are several quantized model (Eager Mode Quantization) that is very useful for me to learn quantization. In recent years, Transformer model is very popular. I want to learn how to quantized Transformer model, e.g Vision Transformer, Swin Transformer etc, using pytorch official tools like Eager Mode Quantization. I also tried to modify it myself, but failed. I don't know how to quantify 'pos_embedding' (nn.Parameter) and nn.MultiheadAttention module. look forward to your reply.

Research direction

Start in torchvision/models/quantization and review the existing Eager Mode Quantization models. Compare the Vision Transformer and Swin Transformer architectures with PyTorch's quantization tools, focusing on how positional embeddings and nn.MultiheadAttention would be handled. Done would mean a supported quantized vision transformer model with coverage for PTQ or QAT.
