Updated solution to BrokenPipeError: [Errno 32] Broken pipe

I’m nowadays doing a course using jupyter notebooks in order to use pymc3. An error occurred in my notebook when I ran the pm.sample line.

The error is exactly the same as metioned in this post:

In this post @junpenglao recommends the use of cores=1 to solve this problem.

I want to ask now if the issue has finally been fixed in another way, and if not,
what problems can we encounter when sampler with cores=1 ?

Thankyou so much.
