Warnings related to cupy and failed to extract file

[Xin Li]

Hello,

I am trying to build an exe from my python project, which is based on a lot of packages including cupy. For the version without cupy the exe works fine. 

For the version with cupy,

I am running this command: pyinstaller --clean --onefile *.spec

In the spec file: 

I set the hiddenimports=['cupy_backends.cuda.stream','cupy._core._carray','fastrlock','fastrlock.rlock','cupy._core._cub_reduction','cupy._core._ufuncs','cupy._core._routines_sorting']

And added 

a.datas += Tree("C:\\Users\\XX\\AppData\\Local\\Programs\\Python\\Python38\\Lib\\site-packages\\cupy\\_core\\include\\cupy", "C:\\Users\\XX\\AppData\\Local\\Temp\\_MEI821682\\cupy\\_core")

When I run the pyinstaller command above, I have 3 warnings:

118455 WARNING: lib not found: nvToolsExt64_1.dll dependency of c:\users\XX\appdata\local\programs\python\python38\lib\site-packages\cupy_backends\cuda\libs\nvtx.cp38-win_amd64.pyd

118572 WARNING: lib not found: cuTENSOR.dll dependency of c:\users\XX\appdata\local\programs\python\python38\lib\site-packages\cupy_backends\cuda\libs\cutensor.cp38-win_amd64.pyd

118651 WARNING: lib not found: cudnn64_8.dll dependency of c:\users\XX\appdata\local\programs\python\python38\lib\site-packages\cupy_backends\cuda\libs\cudnn.cp38-win_amd64.pyd

The exe was generated, when I run the exe, it gives following error:

Failed to extract C:\Users\XX\AppData\Local\Temp\_MEI821682\cupy\_core\README.md: failed to open target file!

fopen: Invalid argument

I am not sure if this is related to the warnings. I googled online and followed some advice.

I tried add datas in *spec:

datas=[('C:\\Users\\XX\\AppData\\Local\\Temp\\_MEI821682\\cupy\\_core\\README.md', '.')], but it complains when running the pyinstaller command since the file does not exist.

I also added the related folders to exclude from my windows defender antivirus scan. But it did not help.

Could someone helping me solving this? Really appreciate your help!

Thanks a lot!

Xin
