FileNotFoundError: Cannot find DGL C++ sparse library 04/26

[ShaohuiLiu]

Hi, I was just trying the new sparse matrix feature and had this error FileNotFoundError: Cannot find DGL C++ sparse library at /home/usr_name/.local/lib/python3.8/site-packages/dgl/dgl_sparse/libdgl_sparse_pytorch_2.0.0.so.
I saw an earlier question with the same issue and solved by updating PyTorch: https://discuss.dgl.ai/t/filenotfounderror-cannot-find-dgl-c-sparse-library/3507

I tried the same way but didn’t work. I had dgl before and already uninstalled earlier versions.

• DGL Version: 1.0.1, dglg0 0.0.2

Hi @ShaohuiLiu ,

DGL 1.0.1 does not support Pytorch 2.0. Could you try the latest (v1.0.2)?

[ShaohuiLiu]

Thanks for the reply. I ended up in another weird issue, somehow I can only install 1.0.1

pip install  dgl -f https://data.dgl.ai/wheels/cu117/repo.html

Could you try again? Here is what I got:
