import error when import GCNConv

[Catriminal]

Hi, after I install torch_geometric and I try to import GCNConv, I got this:

*** Error in `python': corrupted size vs. prev_size: 0x0000559df70d6bd0 ***

and sometimes I can't get any response when I run

import torch
from torch_geometric.nn import GCNConv

My python version is 3.6 and cuda version is 10.1.

Here is how I install torch and torch_geometric. Hope it can help.

pip install torch==1.6.0+cu101 torchvision==0.7.0+cu101 -f https://download.pytorch.org/whl/torch_stable.html

pip install torch-scatter -f https://pytorch-geometric.com/whl/torch-1.6.0+cu101.html
pip install torch-sparse -f https://pytorch-geometric.com/whl/torch-1.6.0+cu101.html
pip install torch-cluster -f https://pytorch-geometric.com/whl/torch-1.6.0+cu101.html
pip install torch-spline-conv -f https://pytorch-geometric.com/whl/torch-1.6.0+cu101.html
pip install torch-geometric

Here is the versions of what I installed.

torch                 1.6.0+cu101
torch-cluster         1.5.9
torch-geometric       1.7.2
torch-scatter         2.0.7
torch-sparse          0.6.10
torch-spline-conv     1.2.1
torchvision           0.7.0+cu101

Is there any advice about this? Thanks for your reading.

You should define the version numbers of external packages in case you are using an older PyTorch version as we don't build new versions of our packages for older PyTorch versions. Those can be found here:

pip install torch-scatter==2.0.6 -f https://pytorch-geometric.com/whl/torch-1.6.0+cu101.html
pip install torch-sparse==0.6.9 -f https://pytorch-geometric.com/whl/torch-1.6.0+cu101.html
pip install torch-cluster==1.5.9 -f https://pytorch-geometric.com/whl/torch-1.6.0+cu101.html
pip install torch-spline-conv==1.2.1 -f https://pytorch-geometric.com/whl/torch-1.6.0+cu101.html
pip install torch-geometric

Thanks for your reply! I installed the versions of packages you mentioned, but it still can't work. I got Segmentation fault (core dumped) when I try to import torch_geometric.

Here is the versions of packages:

torch                 1.6.0+cu101
torch-cluster         1.5.9
torch-geometric       1.7.2
torch-scatter         2.0.6
torch-sparse          0.6.9
torch-spline-conv     1.2.1
torchvision           0.7.0+cu101

Besides, I created a new environment with python 3.7. And installed the same version of packages, it worked. So I guess there may be some problems in my previous environment.
