System crash during subgraph extraction step #61

Closed SYLin117 closed 3 years ago

SYLin117 commented 3 years ago

Hi, I was trying to test my dataset using --train-name and --train-test and it just stuck during the subgraph extraction process, then killed itself. I only got some nonrelevant error message here, hope this could help:

Hi, this error is related to multiprocessing in python. You may turn off multiprocessing by appending "--no-parallel" to your command, or try to debug the multiprocessing by using less workers for example.
