No module named 'ray.rllib.agents.ppo.ppo_policy'

Question

I have this code:

from copy import deepcopy
import json

import ray
try:
    from ray.rllib.agents.agent import get_agent_class
except ImportError:
    from ray.rllib.agents.registry import get_agent_class
from ray.rllib.agents.ppo.ppo_policy import PPOTFPolicy
from ray import tune
from ray.tune.registry import register_env
from ray.tune import run_experiments

I am getting the error:

No module named 'ray.rllib.agents.ppo.ppo_policy'

I tried:

pip install ray;

Answer 1

I re installed the system and reconfigured the environment to solve this problem
