ValueError

[sunville]

I use neat-8.0 version package.

I run the script like this:
./gym_solver.py --episodes=3 --generations=100 --num-cores=1 --max-steps=10

No matter what the max-steps I set I always get this error message in generation 1

Traceback (most recent call last):

And this problem only happens in simulating 'Breakout-v0'
