How to print the solution without stringify?

[Lionel C]

Hi,

I am starting to use the Deap framework in order to complete my MSc project. The topic of my dissertation is to apply Machine Learning techniques to finance and I have chosen to focus on genetic programming.

To get started, I read the documentation and tried to understand some of the examples provided, including symbreg.py. I have been trying to print the solution, but the stringify function was removed from the framework and I could not figure out how to do without it. I tried adding these lines at the end of main():

    tree = gp.PrimitiveTree(hof)

    print(tree)

but I get the following error message:

    AttributeError: 'Individual' object has no attribute 'arity'

I also tried:

    print(hof)

but it would print a list of object references.

Could anyone please guide me?

Hi Lionel,

The HallOfFame is a list of individuals (see the documentation). Therefore, to print the first best's representation, you have to access the list using the square brackets, such as :

print(hof[0])
