Running DEAP-GP_symbreg.py project in debug mode

[Andrew Gleibman]

Hello, I would like to better understand the code of this Symbolic Regression project. 

For this purpose I am trying to set a debug breakpoint in function algorithms.eaSimple(...), which is called in function main(). However, Python does not allow me to set such a breakpoint even if I set verbose=__debug__.  

Is there a way to debug-view the running of this function? (I use Visual Studio Code for running Python).

Thank you,

Andrew
