CUDA enabled version installation problem

[Ryan12345678910111213]

error 5.txt
When I tried to do CMAKE_PREFIX_PATH=$CONDA_PREFIX make build_cuda flags="-DRPU_CUDA_ARCHITECTURES='86'", I got the error message in the error5.txt

Pytorch version: 2.0.1 torchvision 0.15.2
Package version: aihwkit 0.7.1
OS: Ubuntu 22.04.2 LTS (GNU/Linux 5.15.90.1-microsoft-standard-WSL2 x86_64)
Python version: 3.8.17

Cuda compilation tools, release 11.5, V11.5.119

It looks like that it cannot find a properly installed torch. Can you try to open python and try 'import torch'?

Or better still try:

/home/yuz422/venv/bin/python  -c "import torch; print('1' if torch._C._GLIBCXX_USE_CXX11_ABI else '0')"

If that does not work, you might have two python installations and installed the torch under the wrong one.

It does not work. This is strange because I had already installed pytorch using conda install -c pytorch in miniconda. Could you please give me more suggestions?

[maljoras]

You have venv and base activated. Not sure what you are doing there. Typically you have either venv or miniconda installed. You are apparently activating the venv where your python is stored but if you do conda install then it will store it under conda. You could use python -m pip install torch then it would install it under your current environment. But it is not a good idea to have two pythons installed at the same time.

[maljoras]

For the conda package, you need to download the file first. As you can clearly see from the error message it cannot resolve the file path as it is interpreted as an malformed URL.

[Ryan12345678910111213]

Yeah, that's what I find strange. In fact, I've already downloaded the conda package and extracted it to the path /home/yuz422/aihwkit-condapkg.

[maljoras]

Could be that you need file:///home/yuz422/aihwkit-condapkg/ instead of file:/home/yuz422/aihwkit-condapkg/

[maljoras]

Indeed, it needs to have file:/// (3x /). It is wrong in the documentation, we will fix it.

(1) I have completed the whole installation process on my own computer, but I still can't run the program. I can't find this error on the Internet. Could you please give me some advice?
