@yangninghua I have the same problem. Have you solved this problem?

@speedinghzl @yangninghua @yenpengsun I also got the problem mentioned above "AssertionError: Default process group is not initialized". Do you guys have any idea about this?

@yangninghua "gave it up" means you did not manage to run this project?

Thank you in advance!
