No non-repeatable submessage field "pokemon_family"

I'm getting this message when running demo.py:

Traceback (most recent call last):

    raise ValueError(error_msg % field_name)
ValueError: Protocol message has no non-repeated submessage field "pokemon_family"

Is there some setup step I have missed?

I guess you did not receive a valid response from Inventory(item) ? It's empty or something..
