Cartpole example is not working in colab.

Cartpole example

https://colab.research.google.com/github/google/dopamine/blob/master/dopamine/colab/cartpole.ipynb

Is pretty much out of date...

Using it's code on C51, it throws this error on my local machine:

```
~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~
RuntimeError: in user code:

RuntimeError: x: Attempting to capture an EagerTensor without building a function.

```

On colab, I can't even get there, because there's an PIP version installed, and that doesn't works. Only github version works with DQN example, but C51 example is non-functional.
