Be confused about dgl.ops installing

Questions
#1

when I have installed the dgl framework, I hope to use edge_softmax. So I have to use the command

from dgl.ops import edge_softmax

but it occur some issues:

ModuleNotFoundError: No module named ‘dgl.ops’

Is it the reason that dgl version is not matched?

#2

Yes, you should use dgl 0.5+

#3

thanks a lot! But my cuda is 10.0. I think I could replace it with

from dgl.nn.pytorch.softmax import edge_softmax
