Specifed moudle not found: fitness.xxx about ponyge2 HOT 12 CLOSED

Can you run:

python3 ponyge.py --fitness_function string_match

Notice we just use string_match, not string_match.py.

Also, to run this we have to be in the src directory.

Yes I can run that.
Sorry I had tried with and without .py and still getting the error

from ponyge2.

I also tried copying the file string_match.py to string_match2.py (and of course changing the name inside the file also). And now python3 ponyge.py --fitness_function string_match2 also works for me. So the mechanism is working as expected. I have to suspect something in the file xxx.py - either location, name, or name inside the file is not as expected. Would you like to post it?

from ponyge2.

Yeah I just tried to copy the string match and changed the name and it works fine. I'll include my fitness function.

from fitness.base_ff_classes.base_ff import base_ff
import time
from DOOMGame import mybehaviours

class doom_fitness(base_ff):
    def __init__(self):
        super().__init__()
    
    def evaluate(self, ind, **kwargs):
        p = ind.phenotype
        print("\n" + p)
        fitness = 0

        for trial in range(50):
            self.test_spec = getSpec()
            # generatelist should be the hand coded one
            d = {'test_spec': self.test_spec}

            try:
                t0 = time.time()
                exec(p, d)
                # algo p, parameters in d
                t1 = time.time()
                
                guess = d['return']
                print (guess)
                fitness += len(p)
                # adding length of p to represent complexity of algorithm
                
                #run game passing guess as the created tree
                # I know it's not finished here but that shouldn't affect the module not found I don't think
            except:
                fitness = self.default_fitness
                break
        return fitness

def getSpec():
    return mybehaviours.npcSpec()

I removed my usage of function from the mybehaviours file and i could run my program. Is there any way I can import functions?

from ponyge2.

Yes. If the module you want to import is installed system-wide it should work directly. If it's in the source tree, then at least it works if it's in the current directory. So, if I put this in string_match.py, and I put test.py in src, then it works:

from test import f

But if I put test.py in fitness, it doesn't work.

from ponyge2.

The function I want to access is in a file in a directory which is inside src.
As soon as I add the function to the fitness file I get module not found without the import it runs without that error

from ponyge2.

The code will run if I place a test file in src.
The issue seems to be when the file is in a directory which is a child of src

from ponyge2.

This works:

python3 ponyge.py --fitness_function string_match2

Where string_match2.py is in fitness, and it runs:

from fitness.testdir.test import f

and fitness/testdir includes the file test.py.

I'm not very clever at Python sub-modules etc., but yes, it seems to be possible!

from ponyge2.

I've been playing around with it and it seems to working now.
I was trying to import from a fairly large package and the error seemed to be coming from having an init.py in the subpackage. Thank you for your help :)

from ponyge2.

The issue seems to persist if I'm importing in the file I'm importing. It seems to be a mess of python submodules

from ponyge2.

My example above seems to show hot to import from within the import. So I believe this can be closed but please reopen if there is something specific not working.
