Spodernet `TypeError: 'NoneType' object is not callable` issue

I got an email with the following commands / errors.

1)

Here my reply to the issue:

The problem is your PyTorch version. ConvE now supports the latest version PyTorch v0.4. If you want to use PyTorch version v0.3 you can use the commit 5f9f39fdaab153b63cf299f6c5d93da9e13be684 for ConvE and the commit 5f9112810653b85ad27545681123e2deec258652 for spodernet. With these changes, everything should work. Another solution would be to upgrade your PyTorch version.
