When running the example notebook, I came across two problems:
The following warning appears over 5000 times:
WARNING:tensorflow:You are casting an input of type complex128 to an incompatible dtype
float64. This will discard the imaginary part and may not be what you intended.
There's an error in code cell 41, although the notebook does continue to execute despite this.
