I identified the issue! The following lines are missing in all extensions:

#ifdef _WIN32
#include <Python.h>
PyMODINIT_FUNC PyInit__scatter(void) { return NULL; }
#endif

I will run some more tests and will release a new version soon! Sorry for all the trouble 😃

Windows installation indeed needs some fixes to Pytorch, see here. I am still unsure why the installation of the binaries does not work for some. Can you try to do:

pip install https://s3.eu-central-1.amazonaws.com/pytorch-geometric.com/whl/torch-1.4.0/torch_scatter-latest%2Bcu101-cp37-cp37m-win_amd64.whl
