Description
Based on this doc, we have to use deepcompressor to build prepare fake-quantized checkpoint. However, it's a lot more trouble to set up that repo and it seems to me that tool is not being maintained well, especially for new llama models like 3.1/3.2. At least I was not able to do it successfully for llama 3.1 8b.
It would be great if we can add more native support for w4a8 quantization in the trtllm.
