To run the bilby examples using the ptemcee module, you will need to run the following commands at the beginning of your notebook

import multiprocessing
multiprocessing.set_start_method('fork')

There is currently an issue open on the bilby repository that will address this automatically in the future. For now, you will receive a warning whenever you use ptemcee with more than one thread, even if you have set the start method. We will remove this warning once bilby patches their bug.
