Not able to preview the game after installing the latest versions using pip. #134
Description
I installed the following:
pip install gym_super_mario_bros nes_py gym 0.26.2
gym-super-mario-bros 7.4.0
code:
from nes_py.wrappers import JoypadSpace
import gym_super_mario_bros
from gym_super_mario_bros.actions import SIMPLE_MOVEMENT
env = gym_super_mario_bros.make('SuperMarioBros-v0')
env = JoypadSpace(env, SIMPLE_MOVEMENT)
done = True
for step in range(5000):
if done:
state = env.reset()
state, reward, done, info = env.step(env.action_space.sample())
env.render()
env.close()
error:
