Saving variables & fitness from all generations?

[jwalks31]

Hi and thanks for the package!

After a ga has run, is there a way to save or output all variables & fitness values that the algorithm iterated through as it was running? Similar to the output_dict's 'last generation', but for all generations?

@jwalks31 yes, u can create your callback which will save/print/plot any data each 1 generation

use callback like

def action(data):
      # code
      return data

middle_callbacks = [
      MiddleCallbacks.UniversalCallback(action, ActionConditions.EachGen(generation_step = 1))
      ]

where action function is your action, take a look at https://github.com/PasaOpasen/geneticalgorithm2#middle-callbacks

Got it working! Thank you!!

Hi, I get the following error when I follow the solution above

TypeError: 'AlgorithmParams' object does not support item assignment

Any idea what I'm doing wrong?

def action(data):
        return data

middle_callbacks = [
        MiddleCallbacks.UniversalCallback(action, ActionConditions.EachGen(generation_step=1))
    ]

model.run(
        no_plot=True,
        disable_progress_bar=True,
        disable_printing=True,
        middle_callbacks=middle_callbacks,
    )

Thank a lot for the improvements and support!

No problem. I've resolved the problem for myself by removing lines 455 and 457 of geneticalgorithm2.py. This works in my case because I only need to access the data and not change it. Sorry I can't be of more help in fixing the issue, it's beyond my skill.

  File "[redacted]\geneticalgorithm2\geneticalgorithm2.py", line 762, in run
    total_middle_callback()
  File "[redacted]\geneticalgorithm2\geneticalgorithm2.py", line 493, in total_middle_callback
    set_data(data)  # update global date if there was real callback step
  File "[redacted]\geneticalgorithm2\geneticalgorithm2.py", line 455, in set_data
    self.param['parents_portion'] = data['parents_portion']
TypeError: 'AlgorithmParams' object does not support item assignment

fixed this bug in new version 6.4.1
