UnicodeDecodeError when trying to build SageAttention

[gzzhongqi]

I try to install sageattention for comfyui but I keep getting the following UnicodeDecodeError. I tried looking up online but couldn't find any relevant info. I have a 3090 with cuda 12.4+pytorch 2.5.1. Thanks so much for all your hardwork!

Same problem. It seems that the latest version of the code has a little error. I temporarily installed it successfully using another older fork.

[jason-huang03]

We will try to reproduce the problem on 3090.

Thanks for your hard work. My OS is Traditional Chinese and the error message is "cp950 codec can't decode..." but not "gbk". It seems to have something to do with the language of the OS?

I found a fix. I turned on "use unicode utf-8 for worldwide language support" in windows and the error is gone. I guess the error has something to do with the code not handling non-unicode system language packs

Status update: problem fixed when I turned on "use unicode utf-8 for worldwide language support"， thank all you guys!

change the setup.py
