I really need your help urgently! Please!

[PaperRan]

Perhaps you can change the encoding *SUBPROCESS_DECODE_ARGS to some other explicitly defined encoding, such as "gbk" or "utf-8".

[LiGuo12]

same issue

[Nothingbutfish]

to record my experience:
First，I find that ninja and cl is not working as my expect. So I add them to the system path. In addition, don't change the cpp_extension.py.Then the error changes to:

CreateProcess failed: The system cannot find the file specified.

Secondly, I find there is a param in my cpp_extension.py, which was named "CUDA_CLANG_VERSIONS".(different environmen seems produce difference content in the file). The cuda is listed from 11.1 to 11.7.

I don't what it actually mean but I guess the cuda version 12.1 is not supported or it can't be successfully recognized in the code.
What's more, I accidentally came across it online that vs2022 seems to needs cuda version>=11.8.

[AnFeiFei]

I also encountered this issue while working with a project on GitHub. The problem is caused by a mismatch in the character encoding of the Windows command-line tool. You can try setting the Windows system character encoding to UTF-8.

I used the following method, but please note that this modification might potentially cause garbled text issues:

Type "Language" in the Windows search bar and open the Language settings.

Click on "Administrative language settings".

Click on "Administrative" and then select "Change system locale".

Check the option "Beta: Use Unicode UTF-8 for worldwide language support", click "OK", and restart your computer.

I hope this helps!
