I find the use of garbage collector usefull when using the pygad on colab, because when I tried to train some examples on standard version of quotas colab (12GB RAM), not PRO, the usage of memory exceeded the quantity available and so the colab restarted itself not allowing to train for more than 3 generations. With
gc.collect()used outside ofon_generationor inside was possible to release the memory and not crash.
