Description
I've noticed that a lot of the code in Ch 6 is constantly setting random_state = 1. I may be wrong, but I'm fairly sure this is equivalent to fixing the random state of the PRNG at each function call where that argument is passed.
That's bad usage of prngs. You generally do not want to seed a PRNG many times -- just once -- because they only function as intended if they're run as a single long chain.
So: we should look through the book carefully once we have done the first round of polish to check for this bug.
