Can't import dgl (circular import error)

[dosre]

I am having trouble installing dgl (cpu version). I’ve tried with both pip and conda, but in both cases I get the error.

AttributeError: partially initialized module ‘dgl’ has no attribute ‘graph’ (most likely due to a circular import)

I’m using python 3.10 in a virtual environment. I have the cpu version of torch 2.2.1 installed.

Could someone help with this please?

what is your OS version? How do you install DGL? Did you uninstall previous versions of DGL beforehand?

Refer to Deep Graph Library for install command.

I’m running Fedora 39. I followed the instructions here: Deep Graph Library.

When I tried installing with pip I did

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

And when that didn’t work I uninstalled them and tried
conda install -c dglteam dgl

Both times I got the same circular import error when importing dgl, but I did not see any errors during installation.

Could you try to build from source on your platform by referring to Install and Setup — DGL 2.1.0 documentation ?
