PGTG is available on PyPi and can be installed with all major package managers:
pip install pgtg
The easiest way to use PGTG is to create the environment with gymnasium:
import pgtg
env = gymnasium.make("pgtg-v2")
The package relies on import
side-effects to register the environment name so, even though the package is never explicitly used, its import is necessary to access the environment.
The environment constructor can also be used directly:
from pgtg import PGTGEnv
env = PGTGEnv()
