try to run the first time, but failed.

[yogyan6]

I downloaded sc2 and pysc2, and I want to use pycharm to run the first code. The protobuf version is too high, and I changed to a lower version. the following is my code and error code: from pysc2.agents import base_agent from pysc2.env import sc2_env from pysc2.lib import actions, features, units from absl import app import random

class PyAgent(base_agent.BaseAgent): def step(self, obs): super(PyAgent, self).step(obs) return actions.FUNCTIONS.no_op()

def main (unused_argv): agent = PyAgent () try: while True: with sc2_env.SC2Env( map_name="Simple64", players=[sc2_env.Agent(sc2_env.Race.terran), sc2_env.Bot (sc2_env.Race.random, sc2_env.Difficulty.very_easy)], agent_interface_format=features.AgentInterfaceFormat( feature_dimensions=features.Dimensions(screen=84, minimap=64), use_feature_units=True), step_mul=8, game_steps_per_episode=0, visualize=True) as env: agent.setup(env.observation_spec(), env.action_spec())

            timsteps = env.reset
            agent.reset()
            while True:
                step_actions = [agent.step(timsteps[0])]
            if timsteps[0].last():
                break
            timesteps = env.step(step_actions)
except KeyboardInterrupt:
    pass

if name == 'main': app.run(main)

[Sithael]

The error you're encountering is due to changes in the random.shuffle() function in Python versions later than 3.9. Specifically, in Python 3.9 and earlier, random.shuffle() allowed for an optional random function to determine the order of shuffling, which is not the case in Python 3.11 that you are using. I faced a similar issue with Python 3.11. An effective solution is to downgrade your Python version to 3.9. In my experience, Python 3.9.17 worked seamlessly.

solution: If there are too many error parameters, change the color.py in the pysc2 package

before fixing

random.shuffle(palette, lambda: 0.5)

Modified

random.shuffle(palette)
