There is a OSError after install the torch_scatter

[shxzhao]

After install torch_scatter, there is a problem:
OSError: /home/zhao/anaconda3/envs/pytorch2/lib/python3.6/site-packages/torch_scatter/_version.so: undefined symbol: _ZN5torch3jit17parseSchemaOrNameERKSs

How to solve it

This usually indicates a version mismatch between PyTorch and CUDA and torch-scatter. Can you give more information to resolve this?

[shxzhao]

Thanks for you reply! My PyTorch is 1.4.0, CudaToolKit is 10.1, torch_scatter is torch_scatter-2.0.3-cp36-cp36m-linux_x86_64.whl. The torch_scatter is download in https://pytorch-geometric.com/whl/torch-1.4.0+cu101.html.

Mh, that's weird. Can you uninstall all torch-scatter versions (repeatedly call pip uninstall torch-scatter) and run pip install --no-index torch-scatter -f ...?

[janosh]

Had the same problem as @shxzhao. This fixed it for me:

pip uninstall torch-scatter && pip install --no-index torch-scatter -f https://pytorch-geometric.com/whl/torch-1.7.0+cpu.html

Thanks @rusty1s.

[shxzhao]

Thanks! @rusty1s @janosh But it does not work. I'll try something else.

[shxzhao]

Thanks! @rusty1s @janosh When I change the pytorch to 1.7, I succeed!

@shxzhao can you list all your dependency with version? Because I am getting the same error. Downgrading the torch from 1.8 to 1.7 and 1.6 didn't help me

[shxzhao]

@ninjakx My cuda is 10.2, pytorch is 1.7.2, torch_scatter is 2.0.5. I hope it's helpful to you.

[zhouyupeng973]

my torch is 2.1.0 and my cuda is 12.0,which torch_scatter edition should I downlload?

[rusty1s]

You can install from https://data.pyg.org/whl/torch-2.1.0+cu121.html
