Reproduction (REQUIRED)

Please provide a short code snippet (less than 50 lines if possible) that can be copy-pasted to reproduce the issue. The snippet should have no external library dependencies (i.e., use fake or mock data / environments):

# Grabbed from the documentation, https://docs.ray.io/en/master/rllib-training.html#basic-python-api
import ray
from ray import tune

ray.init()
tune.run(
    "PPO",
    stop={"episode_reward_mean": 200},
    config={
        "env": "CartPole-v0",
        "num_gpus": 0,
        "num_workers": 1,
        "framework": "torch",
        "seed": 1234,
    },
)
