Hello and thank you for building PyGAD! It is an awesome module.

I am attempting to load a model checkpoint simply to export the plots.

The issue I am running into is the model appears to try and start running when I use pygad.load() on a model checkpoint (I set the number of generations arbitrarily high). Similarly, I found it odd that I had to have the callback and fitness function defined to be able to load the model.

The code:

import pygad
from main import callback_generation
from fitness import fitness_function

path = '../results/2023_01_31_15_05/model/genetic_2023_01_31_15_05_1744.pkl'

model = pygad.load(path)

model.plot_fitness()
model.plot_new_solution_rate()
model.plot_genes(plot_type='scatter')
model.plot_genes(graph_type='boxplot')

When I run pygad.load, the loaded genetic algorithm immediately creates a population and tries to run. Because I moved this model to another machine, this ultimately fails due to a missing file.

The error message (slightly redacted): 
FileNotFoundError: [Errno 2] No such file or directory: '../results/2023_02_06_14_42/...

It would be ideal if a user could load any model checkpoint to investigate it and the solutions without needing the callback and fitness functions or the model immediately attempting to run().
