Doesn't work properly under wsl2

[CarbonPool]

I am not sure whether cuda can work normally under wsl2. I should have completed the necessary dependency compilation. This is some error message: Failed to load CUDA modules. Please check the CUDA Settings.

Add some additional information:
os: windows10 insider preview 20190
gpu: rtx 2070super
gpu driver: 455.41

wsl2: ubuntu 18.04
cuda: cuda-toolkit-10-2

I do not have Windows CUDA available. So I can't test it.

module 'cutorch' not found

Maybe when you build distro, CUDA cannot be detected and the library for CUDA is not built.
This may help. nagadomi/distro#9 (comment)

Thank you, I solved this problem, but I encountered another difficulty, this is the error message:

I made it! After completing the correct cuda configuration, clean up the failed luarocks cache, and then initialize and install the lua dependency module of waifu2x, and execute it in the waifu2x directory:
rm -rf ~/.cache/luarocks/
./install_lua_modules.sh

Training the waifu2 model on Windows Subsystem for Linux 2 is a good solution

Thank you for reporting.
I didn't expect waifu2x to work with WSL2.
