Description
hi
i'm having issues running FastChat on an Apple Silicon M1 machine with 16G of RAM.
i'm using the `--device mps --load-8bit` options but i keep getting a runtime error.
`RuntimeERror: Userspecified an unsupported autocast device_type 'mps'`
Why is that?
I'm running it within conda with python 3.12.2
when i try
`import torch
torch.backends.mps.is_avilable()`
the results is `True`
which hopefully confirms that my libraries are installed correctly...
I manage to get the inital prompt loaded, but the moment i type a question. the runtime error is thrown.
What am i doing wrong?
Thanks

Research direction
Reproduce the reported FastChat invocation with `--device mps --load-8bit` on Apple Silicon using Python 3.12.2, and capture the full runtime traceback. Start by tracing the device and autocast handling that produces the unsupported `mps` error; done means the cause is identified and the supported behavior or required compatibility change is documented.
