fused_act problem, ninja build stopped, because cannot open file 'python310.lib'

Thanks for the code. Does anybody have had same problem with me? I got problem on fused_act.py and upfirdn2d.py here is my error message:

File "E:\face\code\pytorchNo1\venv\lib\site-packages\torch\utils\cpp_extension.py", line 1740, in _run_ninja_build subprocess.run( File "C:\Users\YJJEON\AppData\Local\Programs\Python\Python310\lib\subprocess.py", line 524, in run raise CalledProcessError(retcode, process.args, subprocess.CalledProcessError: Command '['ninja', '-v']' returned non-zero exit status 1.

The above exception was the direct cause of the following exception:

Thank you!

Hello! I encountered the same problem, @kangjh0226, and managed to find a workaround:

You need to copy lib from your python path: ...\Python\Python310\libs\python310.lib

to your venv folder:

venv\Scripts\libs\python310.lib

I have no idea why it behaves like that but somehow it works for me
