I found this short book at Barnes & Noble at El Cerrito Plaza and read through it. It’s pretty interesting, but I ran into problems about 3/4 of the way through because it turns out that Rasa doesn’t work with Python 3.7, and trying to run it on 3.6 in a Docker container had other problems that I didn’t have time to solve.
It might be better to go through the official docs than use that book.
If anyone is interested in this topic, we could try building a “rubber duck debugging” bot at one of the upcoming Wednesday meetups.
