Description
when I use the apex.amp to train, some wrong like this:
File "/home/cumt_506/anaconda/envs/zyh/lib/python3.7/tkinter/__init__.py", line 3507, in __del__
self.tk.call('image', 'delete', self.name)
RuntimeError: main thread is not in main loop
Tcl_AsyncDelete: async handler deleted by the wrong thread
Aborted (core dumped)
I have tried many times but failed to solve it. Have you ever encountered this problem?

Research direction
Start by reproducing training with apex.amp and review the reported tkinter traceback, including the thread context around image cleanup and the Tcl_AsyncDelete abort. No source file or test is named in the issue; done would mean identifying the cause and confirming that the training process no longer crashes.
