[rank0]:[W325 17:16:26.189312881 ProcessGroupNCCL.cpp:1496] Warning: WARNING: destroy_process_group() was not called before program exit, which can leak resources. For more info, please see https://pytorch.org/docs/stable/distributed.html#shutdown (function operator())

WARNING 03-25 17:11:56 [worker_base.py:561] passing worker_cls as a class object is strongly deprecated, as the serialization of class objects can be tricky and error-prone. To be safe, please keep the class in a separate module and pass the qualified name of the class as a string.
