Yiwen Shi 3a9e33dca8 [torchelastic] Don't do signal handling when off the main thread (#135088) ... Summary: In multiprocessing, signal handling is not possible if the thread is not the main thread. This resulted in the following error: > "ValueError('signal only works in main thread of the main interpreter')" To address this issue, the diff checks whether the thread is the main thread and, if not, skips signal handling.
