Testing a single experiment: tried to access nonexistent attribute or method.

Hi, I experienced an issue when following your instructions and testing the installation.
I'm using Ubuntu 20.04 and installed the CPU version of Pytorch.

When testing the single experiment (bash run_single_cpu.sh), I got the following error:

Traceback (most recent call last):

I found a seemingly closely related problem, see this post: rusty1s/pytorch_sparse#207
and tried to resolve it by downgrading to an older torch-sparse version:

pip install torch-sparse==0.6.12

This seemed to fix the issue.
