Multiprocessing on Windows

[cora-const]

Hi!
I’m trying to familiarize myself with VIP on a Windows machine, but I am running into some multiprocessing issues while working though the tutorials. For example, when trying to run snrmap1 = snrmap(fr_pca1, fwhm_naco, plot=True) from tutorial 1, I get ValueError: cannot find context for 'fork'

I know fork() isn’t supported on Windows; is there a way to get around this without having to install a new OS?

Hi @cora-const, upon asking some VIP users on Windows machines, what has worked for them is WSL: https://learn.microsoft.com/en-us/windows/wsl/install
Apparently it solves all compatibility problems, while allowing you to keep Windows in the background. The first steps at the following link may also be useful for you to get miniconda properly installed with WSL, before installing VIP: https://awhug.github.io/2020-07-10-installing-pymc3-and-theano-on-windows-10-with-wsl/
