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

[devskroy1]

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

[rusty1s]

Have you seen pyg-team/pytorch_geometric#2304? Can you check if the *.so files in the torch_sparse folder exist?

You also may have multiple torch-sparse versions? Can you try to repeatedly uninstall them and install again?

[devskroy1]

Thanks for your reply.
I have now resolved the issue. The *.so files were getting created in the torch_sparse folder. The problem was that the cuda .so files weren't getting created. I had to change the torch_sparse and torch_cluster versions.
I don't believe I had multiple torch_sparse versions.

[Andrea-V]

@devskroy1 I am getting the same error. Which version of torch_sparse and torch_cluster did you end up installing?

[fedebotu]

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

3. 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

actually i met with the same issue with you. In my case, *cpu.so file were getting created but no cuda .so files found. How did you. resolve. this problem?

[rusty1s]

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

[KushajveerSingh]

I am also facing the same issue. My environment is

• python = 3.9.4
• pytorch = 1.8.1
• CUDA = 11.1
• torch_scatter = 2.0.6
• torch_sparse = 0.6.9
• torch_cluster = 1.5.9
• torch_geometric = 1.7.0

I installed the packages from pypi and I checked that I was installing using the pytorch 1.8.0 and CUDA 111 link. I tried to do --no-index install but I got the following error

ERROR: Could not find a version that satisfies the requirement torch-sparse
ERROR: No matching distribution found for torch-sparse

I checked that torch.cuda.is_available() returns True. The issue is torch_sparse is not compiling the cuda.so files. I checked by installing the packages from source (except pytorch) and the same error persists. I installed pytorch using the conda command and the version of cuda is 11.1.74.

During the compilation process of torch_sparse it is building cpu packages but not building cuda packages. I can confirm that this error was not occurring with python 3.8 and pytorch 1.7 and cuda 10.

[KushajveerSingh]

@rusty1s I think there is some inconsistency for wheels of pytorch=1.8.0 and cuda=11.1.

Note: python = 3.9.4 did not work. So I am using python = 3.8.8

I installed pytorch=1.8.1 and torch-sparse using below commands

conda install pytorch cudatoolkit=11.1 -c pytorch -c nvidia
pip install --no-cache-dir torch-sparse -f https://pytorch-geometric.com/whl/torch-1.8.0+cu111.html

But the *_cuda.so files were not copied. When I tried pytorch=1.8.1, cuda=10.2 using the below commands

conda install pytorch cudatoolkit=10.2 -c pytorch
pip install --no-cache-dir torch-sparse -f https://pytorch-geometric.com/whl/torch-1.8.0+cu102.html

the *_cuda.so files were copied. Also, compiling torch-sparse from source would not work as when pytorch is installed from conda the environment variable torch.utils.cpp_extension.CUDA_HOME is set to None, so CUDA extensions will never be built.

[rusty1s]

Yes, we currently do not provide Python 3.9 binaries. I will work on that.

I'm not sure if there is a difference between packages with different CUDA versions. You can check by downloading https://pytorch-geometric.com/whl/torch-1.8.0+cu111/torch_sparse-0.6.9-cp38-cp38-linux_x86_64.whl that it also contains the required *_cuda.so files.

I installed PyTorch from conda and CUDA_HOME is set for me. Nonetheless, you can still force CUDA installation by running:

FORCE_CUDA=1 python setup.py install

[KushajveerSingh]

This is interesting. I checked with a clean miniconda installation also that CUDA_HOME was not set after installing pytorch (1.8.1) from conda. Maybe the driver on my machine is not working properly with cudatoolkit that is installed with conda or I am using a maxwell mobile GPU, that is pretty old for cuda 11.

But I got the pytorch_geometric working with cuda 10.2 so I am ok. There are not many features of cuda 11 that my gpu can use, so I am not missing on anything.

I met the same problem and fixed it by installing cuda package.
Check if '/usr/local/cuda-11.x' is existing.
If you only install 'cuda toolkit' in conda virtual env, you can't find it. (refer to below explanation)

My solution is:

1. install 'cuda' (not in conda virtual env)
2. install torch_geometric in conda virtual env using below commands
   conda create -n XXX python=3.8
   conda activate XXX
   conda install pytorch==1.8.0 torchvision==0.9.0 torchaudio==0.8.0 cudatoolkit=11.1 -c pytorch -c conda-forge
   conda install pytorch-geometric -c rusty1s -c conda-forge

[KukumavMozolo]

I installed pytorch with conda:
conda install pytorch=1.9.0 torchvision torchaudio cpuonly -c pytorch
and pytorch-geometric with:
conda install pytorch-geometric -c rusty1s -c conda-forge

These are the pytorch packages that got installed:

pytorch=1.9.0=cuda112py38h3d13190_1
pytorch-cluster=1.5.9=py38_torch_1.9.0_cpu
pytorch-geometric=1.7.2=py38_torch_1.9.0_cpu
pytorch-gpu=1.9.0=cuda112py38h0bbbad9_1
pytorch-scatter=2.0.8=py38_torch_1.9.0_cpu
pytorch-sparse=0.6.11=py38_torch_1.9.0_cpu
pytorch-spline-conv=1.2.1=py38_torch_1.9.0_cpu

When importing:
from torch_geometric.data import Data
I get the above error as well

[rusty1s]

Note sure why you have a PyTorch version installed with CUDA support although you have specified thecpuonly flag, but I'm fairly sure that this explains the error.

[KukumavMozolo]

As a side note:
I tried to install the packages with an environment.yml
`channels:

• conda-forge
• anaconda
• pytorch
• rusty1s
  dependencies:
• pip==21.0.1
• python==3.8.11
• gql==2.0.0
• graphql-core==2.3.2
• flask==1.1.2
• pytorch
• torchvision
• torchaudio
• cpuonly
• pytorch-geometric`

this led to the inconsistent packages. I fixed it by explicitly stating packages e.g:
` - pytorch=1.9.0=py3.8_cpu_0

• pytorch-cluster=1.5.9=py38_torch_1.9.0_cpu
• pytorch-geometric=1.7.2=py38_torch_1.9.0_cpu
• pytorch-scatter=2.0.8=py38_torch_1.9.0_cpu
• pytorch-sparse=0.6.11=py38_torch_1.9.0_cpu
• pytorch-spline-conv=1.2.1=py38_torch_1.9.0_cpu`

[rusty1s]

There is also a PyTorch conda package in conda-forge which is picked up (rather than the one from the -c pytorch channel). Swapping the order of channels, i.e., putting pytorch before conda-forge, should fix this.

this is work for me. thanks :)

Hi all, currently experiencing this issue only when I run torch on GPU, but everything works fine. I usually use torch==1.12.1+cu116, but had to downgrade to torch==1.8.1+cu111 to be able to import torch_geometric on just CPU. This is the error I get when I try and import torch_geometric on GPU:

I installed all packages as per PyTorch guidelines:

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

pip install torch-spline-conv -f https://pytorch-geometric.com/whl/torch-1.8.1+cu111.html
pip install torch-geometric

In regard to the .so files, I am having the issue of only having *_cpu.so files and no *_cuda.so files in my torch_sparse, torch_scatter etc. directories in the site-packages/ directory of my venv. Any help on this would be greatly appreciated as I am currently trying to train a transformer+GCNN on just cpu...... which will be done when I'm 90 years old.

[rusty1s]

Please install via --no-index option for later PyTorch versions:

pip install --no-index torch-scatter -f https://pytorch-geometric.com/whl/torch-1.8.1+cu111.html
pip install --no-index torch-sparse -f https://pytorch-geometric.com/whl/torch-1.8.1+cu111.html
pip install --no-index torch-cluster -f https://pytorch-geometric.com/whl/torch-1.8.1+cu111.html
