submodules incompatible with downgraded torch by torch-scatter

[nicholasnge]

Hello, looking forward to run your code. However, when I run the conda env setup, I get the error below during pip install submodules. Alternatively, when I manually install the packages, i can pip install submodules but thereafter torch-scatter is incompatible since it downgrades torch to 1.12 from 2.2.2

Wondering how you managed to set it up? Thanks!

looks like the conda install for pytorch-scatter didnt quite work for me, but the pip install works, solved
