Im trying to do a rollout of contrib/AlphaZero , for the cartPole example. But im getting this error.
for i, episode in enumerate(episodes):
TypeError: ‘NoneType’ object is not iterable
There is another way to do the rollout?
Im using this CLI command:
rllib rollout /Path/to/checkpoint --run contrib/AlphaZero --env CartPole-v0 --steps 10000 --out rollouts.pkl
