pytorch_sparse: osx cpu only version fails with missing native library: symbol not found

https://stackoverflow.com/questions/67455890/pytorch-cpu-only-on-osx-fails-with-symbol-not-found

I am trying to get started with PyTorch - on a mac osx computer. However, basic steps fail:

    from torch_sparse import coalesce, SparseTensor

I am using a conda environment of:

    name: my_conda_env
    channels:
      - pytorch
      - conda-forge
      - defaults
    dependencies:
      - python>=3.8
      - pytorch
      - pytorch_geometric

and instantiated it using:

conda env create --force -f environment.yml
