Question about the cuda version.

❓ Questions & Help

I use Arch Linux, and I looked up my cuda version through package management

pacman -Q cuda
cuda 11.0.3-1

However, when I run

python -c "import torch; print(torch.version.cuda)"
10.2

The cuda version is inconsistent. I think maybe pytorch automatically install a cuda version for me?

But when I import pytorch_geometric

OSError: libcusparse.so.10: cannot open shared object file: No such file or directory

So how to solve it? I have no problem when I was working with pytorch.

working now. Here is the below commands followed Incase if anyone need

conda create --no-default-packages -n myenv python=3.7
conda activate myenv
conda install pytorch torchvision -c pytorch
pip install torch-scatter==latest+cu102 -f https://pytorch-geometric.com/whl/torch-1.6.0.html
pip install torch-sparse==latest+cu102 -f https://pytorch-geometric.com/whl/torch-1.6.0.html
pip install torch-cluster==latest+cu102 -f https://pytorch-geometric.com/whl/torch-1.6.0.html
pip install torch-spline-conv==latest+cu102 -f https://pytorch-geometric.com/whl/torch-1.6.0.html
pip install torch-geometric

Now I typed "find . -name "libcublas*" in my home directory

output gave me

Finally I added this to my .bash_profile and everything is working perfect

export LD_LIBRARY_PATH="$HOME/anaconda3/pkgs/cudatoolkit-10.2.89-hfd86e86_1/lib/:$PATH"

[jmandivarapu1]

I got below and tried to set it as export LD_LIBRARY_PATH= ~/anaconda3/lib/ or export LD_LIBRARY_PATH=~/anaconda3/lib/libcublas.so.10.0.130.' Both didn’t work. Can you help in which of the below to set as path?
