[Build] How can I quantize the llama3 model activation to int4 ? #21334

Open zhangyu68 opened 3 months ago

Describe the issue

I’m trying to quantize a int4 model, but this file only provides the weight-only-quantization. If I can quantize both weight and activation to int4 ? https://github.com/microsoft/onnxruntime/blob/main/onnxruntime/python/tools/quantization/matmul_4bits_quantizer.py

Thanks for your help!
