Parallel Problems

[spot92]

I am able to run your code when I manually set num_workers = 1, but anytime I try to use parallel, I get the following:

Hello spot92, thanks for finding my repository and playing around with my code.

I presume you were running the code on a Windows machine. Unfortunately I haven't tested the code on a Windows machine yet. I will do so once I continue to work on this project.

Sadly I cannot recommend using my software at the moment. I actually plan on rewriting the package to wrap existing C++ code which is fully tested. Then I will also test that all features run on all operating systems..
