I left the computer running the Metropolis sampler. After 5hs (I wanted many samples because why not) the computer finishes sampling but remains busy still for more the 10hs. What is PyMC3 doing?
There’s no doubt It is actually doing something because there is an active process running (using one core of the cpu at 100%):
I noticed that there is always something being done after sampling (reformating data?) but It never took this long. I’m curious to know why this takes longer than the sampling itself and If there is a way to prevent It from taking so long.
