I try to train cstr model with command: python tools/train.py configs/cstr.py I recieved error:

Exception has occurred: RuntimeError
Default process group has not been initialized, please make sure to call init_process_group.

    runner()

    main()

Can you tell me please, where I wrong?

@ELDIABLO4400 Hi. we set default batch normalization as SyncBn to use distributed training which will cause the problem when run with DataParallel mode. You can use this command tools/dist_train.py configs/cstr.py 4.
