cc1plus not found, luarocks failed to install, and can't find CUDA

[dark-swordsman]

Hello,

I know it's probably a terrible idea, but I am trying to get Waifu2X working on WSL 2 with Ubuntu 20.04. I once tried to install CUDA onto WSL, but it was failing and I gave up quick.

This time, I tried installing CUDA 10 to Windows 10 and am currently in the process of running ./install_lua_modules.sh. When I run it, it shows the following:

CMake Error at /usr/share/cmake-3.16/Modules/CMakeTestCXXCompiler.cmake:53 (message):
  The C++ compiler

    "/usr/bin/c++"

  is not able to compile a simple test program.

  It fails with the following output:

So the main two things:

• cc1plus is missing
• it can't install https://raw.githubusercontent.com/torch/rocks/master/cutorch-scm-1.rockspec

Running th waifu2x.lua causes the following:

Here it seems that it can't find CUDA even though I installed 10.0 via this since the original install through sudo apt install cuda was downloading 11.2.

I figure some of this may be due to it being WSL 2, but I was able to solve the majority of the other issues I had. Just got stuck on this, and running the following to solve cc1plus doesn't work.

sudo apt-get update
sudo apt-get install --reinstall build-essential // works, but doesn't fix the issue

or

sudo apt-get install --reinstall g++-4.6 // results in "Unable to locate package g++-4.6"

I was able to override gcc to version 7.5.0 because of an error about it being 8 or higher (it was 9). Though there's g++ and gcc. I set them both to:

g++ (Ubuntu 7.5.0-6ubuntu2) 7.5.0

This is running on Ubuntu 20.04 on WSL 2.

Let me know if I need to provide any other information.

You need to install torch7 first. https://github.com/nagadomi/distro There are reports that waifu2x worked on WSL2, but I haven't confirmed it. https://github.com/nagadomi/waifu2x/issues/354

[dark-swordsman]

I already have torch7 installed.

I installed it through this method because the method listed on the readme was not working.

I guess the difference is that I just did ./install.sh instead of ./clean.sh and ./update.sh.

I will try the recommendations in that issue you listed and report back.

[nagadomi]

The above error is occurring while trying to install the required cutorch library as a dependency. When installing torch7, cutorch should be installed, but it is not installed. Maybe CUDA is not detected when building torch7 then cutorch is not built. It's the same problem as #354.

You can check it with the following command.

th -e "require 'cutorch'"

If cutorch is installed successfully, it will exit without displaying any message.

[dark-swordsman]

So I made a little progress, but my patience is growing thin. I feel like my WSL 2 instance is nothing like any other instance that anyone else has. Ever since I upgraded to WSL 2, it feels like everything broke and all I can do now is run Minecraft servers or use git.

Running th -e "require 'cutorch'" revealed that it, in fact, was not found. I am not exactly sure of the steps I took to fix it, but I eventually fixed it and NVCC was able to compile. It was something along the lines of:

• re-installing CUDA toolkit
• double checking my symlinks for gcc and g++
• some other steps that I can't remember, but I was just googling the errors and trying anything
• eventually rebuilding torch from here: https://github.com/nagadomi/waifu2x/issues/253#issuecomment-445448928

It now shows:

THCudaCheck FAIL file=/home/dark/torch/extra/cutorch/lib/THC/THCGeneral.c line=70 error=38 : no CUDA-capable device is detected
/home/dark/torch/install/share/lua/5.1/trepl/init.lua:389: cuda runtime error (38) : no CUDA-capable device is detected at /home/dark/torch/extra/cutorch/lib/THC/THCGeneral.c:70

I tried the following guides, to no avail:

• https://docs.nvidia.com/cuda/wsl-user-guide/index.html
• https://forums.developer.nvidia.com/t/failure-to-install-cuda-on-wsl-2-ubuntu/128592/8
• https://forums.developer.nvidia.com/t/no-cuda-capable-device-is-detected/39478/5
• https://ubuntu.com/blog/getting-started-with-cuda-on-ubuntu-on-wsl-2

The only other issue I noticed is that I was unable to install ipython or something when doing ./install-deps, but no errors came from the build process of torch.

I think I will give up on this again and pick up on it some other time, as at this point, it's yet another WSL issue that I've encountered since upgrading to WSL 2 that is literally unfixable.

no CUDA-capable device is detected

GPU driver doesn't seem to detect the GPU device. There are reports that driver installed by recent windows update do not work. https://github.com/microsoft/WSL/issues/6014#issuecomment-730526767

wsl2 is virtualized and shared, and I seem to be able to export my completed image for sharing.

This is my current environment:

windows10:

 ·Version: windows10 insider preview 20279
 ·Nvidia driver: 465.12

windows subsystem for linux:

· Version: Ubuntu 18.0.4 · Kernel: 5.4.72 · cmake: 3.18.0 · gcc: 7.5.0 · cuda: 10.2 *(package cuda-toolkit-10-2)

It works very well recently, but recently Microsoft released the new 21277, I tried to upgrade, even if it works, but the efficiency of waifu2x is lower than the previous branch version, 20279 is the more stable FE dev branch I currently use.

I suggest to remount the new image and start over. My image is from https://cloud-images.ubuntu.com/bionic/current/, I use this rootfs to mount it manually.

[CarbonPool]

In addition, please install cuda correctly according to NVIDIA’s official solution. In wsl2, you don’t need to install additional drivers, just install cuda-toolkit-10-2. Before that, you may need to update the source, please refer to https://docs.nvidia.com/cuda/wsl-user-guide/index.html#installing-wsl2

I had done the installation as intended with just the toolkit, but it wasn't working. Nothing I tried worked, so I gave up on it.

I ended up completely reinstalling Windows since I was having other bugs and issues with it. I also installed Ubuntu 20.04 alongside it so I can dual boot them and not deal with the slew of headaches and nuances that WSL provides.

I have finally finished the installation on my Ubuntu install, and when restarting, all I did was install graphicsmagick and it seems that it works now:

kyle@dark-linux-desktop:~/waifu2x$ th waifu2x.lua 
images/miku_small_noise_scale.png: 0.22278690338135 sec

Perhaps one day I will try WSL again, but it's given me so many problems that it just makes more sense to dual boot linux. I guess you can close this if you want since I will no longer be providing updates or testing with WSL.

Edit: Also, to note for anyone else that may find this: Getting it working on Ubuntu bare metal didn't require the cuda-toolkit, just needed to install the graphics driver at the start when I installed Ubuntu, and then follow the CUDA install steps in the readme.

That's a good idea. I want to use it as a reference for performance loss. What GPU are you using? I use rtx2070super under wsl2, and the consumption under the default output: 0.41919994354248 sec

[dark-swordsman]

I have an RTX 2070. Specifically the Zotac Mini which has the 400-A1 chip and is limited to 200W, instead of the more powerful 400A-A1.

As you can see, it did it in 0.22278690338135 seconds. I can run the default test a few more times tomorrow to get a larger dataset if you want.

After seeing another image take 0.4-1.2 seconds depending on the settings, it made me worried about total performance and if the native batching method improves performance. I was hoping to try to upscale/refresh anime, but that would put the render time of all the frames at about 4-12 hours per 24 minute episode. That's only upscaling/denoising and doesn't account for additional encoding time.

Wow, thanks, I did not expect the performance loss so much, I currently train the model under wsl2.

[CarbonPool]

I also completed the installation of dual systems. In this comparative test, I found that wsl2 has great potential. They have the same configuration. Here are some test information:

（Non-standard test）

·Ubuntu20.04 MEM: 15GB PC POWER: ~330w

·windows10 + wsl2 MEM: ~24GB PC POWER: ~290w

wsl2 did not make full use of the GPU, but it proved enough to have great potential.

After encountering some install issues, torch and waifu2x was up and running in Ubuntu 20.04 with the following configuration:

Install torch-cuda-10: git clone https://github.com/nagadomi/distro.git torch-cuda-10 --recursive

Switch to version 8 of gcc and g++: sudo ln -fs /usr/bin/g++-8 /usr/bin/g++ sudo ln -fs /usr/bin/gcc-8 /usr/bin/gcc

Build torch-cuda-10: cd torch-cuda-10 ./clean.sh ./update.sh

Activate torch-cuda (and optionally place in ~/.bashrc): ./install/bin/torch-activate

Run tests: ./test.sh
