Keras model.fit() runs faster on GPU when the CPU is loaded with a heavy multiprocessing script

I wasn't expecting this to happen. The relevant code pieces are: import os import tensorflow as tf os.environ['TF_XLA_FLAGS'] = '--tf_xla_enable_xla_devices' .

Failing to load model using multiprocessing on windows

This program works on Unix and I'm trying to transition it to windows. It uses multiprocessing and I understand it's an issue with being forced to use spawning
