Agent.learning_rate is never set? #28

Closed halflings closed 7 years ago

halflings commented 7 years ago

I was reading through the code and couldn't figure out where Agent.learning_rate is being set. It's used here:

https://github.com/devsisters/DQN-tensorflow/blob/master/dqn/agent.py#L299

But it's only set on the Config object, not the Agent.

It's quite weird but it is set here.

Thanks! Overall, this implementation is extremely useful to understand DQN, but one thing I don't like is that it's overly complex, with too many abstractions and abusing dynamic features of Python.

Having your config in a dict instead of explicit class attributes only makes the code harder to understand unfortunately.

carpedm20 commented 7 years ago

Yes, I agree on that. That's why I didn't used it in the more recent RL code https://github.com/carpedm20/deep-rl-tensorflow/blob/master/main.py and I never used those code style again.
