描述

CPU model working fine python -m fastchat.serve.cli --model-path /path/to/fastchat-t5-3b-v1.0 --device cpu

GPU models both got errors python -m fastchat.serve.cli --model-path /path/to/fastchat-t5-3b-v1.0 --device mps --load-8bit python -m fastchat.serve.cli --model-path /path/to/fastchat-t5-3b-v1.0 --device mps

So, does fastchat-t5-3b-v1.0 can running on Mac --device mps?

研究方向
The issue reports that fastchat t5-3b v1.0 fails on MPS GPU while CPU works. The error is likely in the model loading or device mapping code. Investigate the fastchat.serve.cli module and how it handles the device and load 8bit flags. The model may need specific quantization or MPS specific adjustments. Look for similar issues or patches in the FastChat repository. The user did not provide full error logs, so reproducing the error with the given commands is necessary.
