The Sequential Agent example in the Getting Started guide doesn't work
I just tried downloading the Sequential Agent from the Getting Started Guide and running it in Colab.
It works up to the point where it tries to run the first agent: run_episode(env,OrderedAgent())
but then fails with an "unhashable type: 'numpy.ndarray'" error.
Similarly the following episode, that runs with a random agent also fails, this time with the error: "run_episode(env,random_agent,False)"
Is this example out of date?
