I am sorry that I can not reproduce my error because my code is too complex.
When I try to train a model, I got the following error.
Traceback (most recent call last): File "/home/xxx/.conda/envs/env_name/lib/python3.8//queues.py", line 239, in _feed obj = _ForkingPickler.dumps(obj) File "/home/xxx/.conda/envs/env_name/lib/python3.8/multiprocessing/reduction.py", line 51, in dumps cls(buf, protocol).dump(obj) _pickle.PicklingError: Can't pickle <class 'numpy.core._exceptions.UFuncTypeError'>: it's not the same object as numpy.core._exceptions.UFuncTypeError
I cannot locate the location of the error. Can anyone give some advice about what’s the type of this error?
