I don't know if this is the right channel for this, but I might have found a typo/mistake in the metaflow book? Specifically for chapter 5's

cooc_multicore.py

, why is this line here https://github.com/outerbounds/dsbook/blob/d84ad6e98feb9bd6bf683eed6bc43f855b0c16f8/chapter-5/cooc_multicore.py#LL24C12-L24C12 necessary? I thought

compute_cooc_multicore

already calls

fast_cooc

in parallel, so we shouldn't need to actually call

fast_cooc

on the matrix before

compute_cooc_multicore

? Or am I misunderstanding something?
