ModuleNotFoundError: No module named 'finite_mdp'

[zsn2021]

When I run the configuration file：
evaluate
configs/HighwayEnv/env.json
configs/HighwayEnv/agents/MCTSWithPriorPolicyAgent/vi_prior.json
--train
--episodes=20
How to deal with such errors？
”ModuleNotFoundError: No module named 'finite_mdp'“

[zsn2021]

I solved this problem by ”pip install finite_mdp“
But there is a new problem ”AttributeError: 'ValueIterationAgent' object has no attribute 'action_distribution'“

[zsn2021]

I did not find attribute 'action_distribution' under 'ValueIterationAgent' object

Hmm that is weird, could you show the error's stack trace, so I can understand what causes the code trying to access the agent's 'action_distribution'? (It shouldnt be needed for the ValueIterationAgent, which atm is deterministic)
