ValueError: Unsupported nproc_per_node value

[GreaBugs]

May I ask if anyone encountered this error while running the file 'dist_train. sh'? I haven't resolved it yet. I don't understand why I made an error before assigning values to the variables in the file. If I receive an answer, I would greatly appreciate it

Hi, the config path and the number of GPU should be specified as arguments when calling dist_train.sh. You can refer to https://github.com/chenhang98/BPR#train-the-network for details.
