Where Can I find the implemented DQfDAgent?

Question

I'm trying to use that Object as This Blog uses in His Code but when I do from rl.agents.dqn import DQfDAgent it returns me and error ImportError: cannot import name 'DQfDAgent' .

I've done a dir(rl.agents.dqn) and there is no DQfDAgent object so, how has the man of the blog done it?

(Update 1)

I've already done this:

pip install -e git+git://github.com/jakegrigsby/keras-rl.git#egg=keras-rl

but it returns this error:

Command "git clone -q git://github.com/jakegrigsby/keras-rl.git C:\Users\myuser\src\keras-rl" failed with error code 128 in None

Answer 1

note that the master version of keras-rl may be missing my additions. See my fork.

Just do a quick search for DQfDAgent and you ll see that it is not in the rl.agents.dqn source code page. Use the branch of the author ( here ) to import properly and use the agent he has implemented but which is not in the official version.

Answer 2

The README.md file of the repo you linked indicates that:

Note that the master version of keras-rl may be missing my additions. See my fork .

In such a fork, you can find an implementation of DQfDAgent in the following code: https://github.com/jakegrigsby/keras-rl/blob/master/rl/agents/dqn.py
