I have the same errors with abasak, since I add some training code of another Neural Network (NN) before the training of GraphSage. Specifically, I utilize the NN to extract features, which are utilized to construct the graph for GraphSage.
Changing the multi-processing start method from ‘fork’ to ‘spawn’ doesn’t address the problem. Another error occurs in blew.

Did you make any changes to the code? Were you creating something on GPU before starting the subprocesses?
Any suggestions about this issue? Thanks in advance!
