Installation Problem

I'm having trouble installing packages due to version conflicts. Can you suggest the right Python version for compatibility with the required packages?

Hi Elif, thanks for your interest in our work. We were using Python 3.8.0 - can you install the packages using this version? If not, it would be nice if you could show the compatibility error.

Thanks for your quick response. I'm currently facing an issue while installing the required packages. Here's the error I encountered:

  Using cached torch-1.8.0-cp38-cp38-manylinux1_x86_64.whl (735.5 MB)

  note: This error originates from a subprocess, and is likely not a problem with pip.

How can I resolve this issue? I haven't found a solution yet. Could it possibly be related to the CUDA version?

I see... Yes, this might be related to the CUDA version. In the past, I've also run into installation issues with torch-scatter. Perhaps you could try manually installing Pytorch first followed by torch-scatter?

According to the torch-scatter documentation, if pytorch >= 1.8.0 is installed then you should be able to install torch-scatter as conda install pytorch-scatter -c pyg (or if you are using pip: pip install torch-scatter -f https://data.pyg.org/whl/torch-1.8.0+${CUDA}.html)
