mae performance results are different in Debug mode and Release mode.

[ahn19]

I ran the following code against the appa face dataset (https://chalearnlap.cvc.uab.cat/dataset/26/description/) https://github.com/yu4u/age-gender-estimation/blob/master/age_estimation/train.py

However, as you can see from the results below, the performance results are different in Debug mode and Release mode (I am using PyCharm). The results in Debug mode are better than those in Release mode.

Why is that so?

release mode result:
