AttributeError: 'NoneType' object has no attribute 'origin'

I am using torch-sparse version 0.6.8 as a dependency for a project I am working on.

However, I get the following error inside the torch_sparse/__init__.py file: torch.ops.load_library(importlib.machinery.PathFinder().find_spec( AttributeError: 'NoneType' object has no attribute 'origin'

It seems that the find_spec() call returns None.

I am running on CUDA on Ubuntu and using torch version 1.7.1 and torch-scatter version 2.0.5 Do you know how I can resolve this error?

Thanks

Did you install the CUDA package, e.g. via https://pytorch-geometric.com/whl/torch-1.8.0+cu111.html? Otherwise, you may try to install with the --no-index option, i.e.

pip install --no-index torch-scatter -f https://pytorch-geometric.com/whl/torch-1.8.0+{CUDA}.html

I will leave my 50 cents here, I tried other methods to solve this problem but then but just got other issues 😅 I solved them by updating to PyTorch 1.8.1 and CUDA to 11.1 (using Ubuntu 20.04). Here are the steps:

1. Update CUDA to the latest version. NOTE: if you encounter problems with the CUDA installation, follow this solution (basically purge the Nvidia drivers and reinstall them so to avoid problems with dependencies)
2. Install latest version of torch with cuda by running this (from PyTorch webpage)

pip3 install torch==1.8.1+cu111 torchvision==0.9.1+cu111 torchaudio==0.8.1 -f https://download.pytorch.org/whl/torch_stable.html

1. Install torch-geometric and its dependencies this in your terminal (from the PyTorch Geometric installation guide):

pip install torch-scatter -f https://pytorch-geometric.com/whl/torch-1.8.0+cu111.html
pip install torch-sparse -f https://pytorch-geometric.com/whl/torch-1.8.0+cu111.html
pip install torch-cluster -f https://pytorch-geometric.com/whl/torch-1.8.0+cu111.html
pip install torch-spline-conv -f https://pytorch-geometric.com/whl/torch-1.8.0+cu111.html
pip install torch-geometric
