Broken Pipe Error and Fixes?

[JessVanN]

Upon running the tutorial code I was consistently hitting a road block with the multiprocessing package this code requires (Running in Windows with Anaconda Install of Python). I had to make the following changes to successfully run the code.

Error:
__ == "main": #added to code to fix pipe closed error https://discourse.pymc.io/t/multiprocessing-windows-10-brokenpipeerror-errno-32-broken-pipe/2259
gm = GenerativeModel(region, model_data)
File "", line 1
__ == "main": #added to code to fix pipe closed error https://discourse.pymc.io/t/multiprocessing-windows-10-brokenpipeerror-errno-32-broken-pipe/2259
^
SyntaxError: invalid syntax

I changed the following in the tutorial.py:
if name == "main": #added to code to fix pipe closed error https://discourse.pymc.io/t/multiprocessing-windows-10-brokenpipeerror-errno-32-broken-pipe/2259
gm = GenerativeModel(region, model_data)
gm.sample()

With this i was able to run the data using Covid Tracker unaltered source.

Upon still receiving errors after adjusting this to fit local state data instead of Covid Trackers CSV, I came aross a similar error, after playing around with it for a few days I changed in the generative.py file:

def sample(
    self,
    cores=1,    #changed was 4
    chains=2,  #changed was 4

But I am concerned because I don't know what these values affect. I assume cores is processing cores used. I am less sure on chains. Can I change this code without changing the model? Or do you have other suggestions to fix the Broken Pipe (Error 32) Errors
