RGCN on GPU getting error

Hi all,

I’m trying to run RGCN code in on GPU. I get the following error:

Is there any part I’m missing?

Hi, could you please share the following information so that we can try to reproduce the error:

  • The dgl version you are using

  • The exact command you used to run the program.

It seems you didn’t install the dgl with cuda support. How do you install it, by source or pip/conda?

Yes, I had dgl installed without cuda enabled.
Thanks! I resolved it with installing the right dgl.
