PointConv class is not found in the torch_geometric.nn module

I am having trouble with the brignet add-on for Blender. The error message suggests that the PointConv class is not found in the torch_geometric.nn module. it’s possible that the brignet add-on specifically requires the PointConv class, which is not available in the torch_geometric.nn module. I've tryed to check the documentation or requirements of the brignet add-on to see if it specifies a particular version of torch-geometric or a different class that should be used instead of PointConv? Using cuda 11.8, Pytorch 2.0.0, Blender 3.0, Python 3.10?

After further investigation I found by looking on the original
repository https://github.com/zhan-xu/RigNet#training that pip install torch-geometric==1.7.2 i s required which solved my issue.
