AttributeError: Can’t get attribute ‘DGLHeteroGraph’ on <module ‘dgl.heterograph’ from ‘/home/ec2-user/anaconda3/envs/JupyterSystemEnv/lib/python3.10/site-packages/dgl/heterograph.py’>

I am using dgl version as below.

print(dgl.version)
1.0.0+cu113

But the dgl graph I built is based on version 0.9, where I installed with dgl-cuda11.3=0.9.0=py39_0.

Any idea how to resolve this problem? Thanks.

Did you save your graph using pickle? Pickle does not guarantee backward compatibility so we recommend saving via dgl.save_graphs.

I may meet this before. I suggest you see the DGL’s documents. try to use the function that corresponds to dgl’s version.
