python - How to get stack trace of exception happening in __del__? -

-

is there easy way stack trace printed exception happens in __del__? in case, there's no __del__ method defined object

exception typeerror: "'nonetype' object not callable" in <bound method interactivesession.__del__ of <tensorflow.python.client.session.interactivesession object @ 0x2867710>> ignored

you'd have detect error manually inside __del__:

def __del__(self):     try:         cleanup()     except exception:         import traceback         traceback.print_exc()          # let error keep propagating.         raise

there's no way configure python exceptions raised __del__. it's direct call pyerr_writeunraisable, no place provide callback, no configuration possible print stack trace, , retrieve exception information afterward.
