Unit test failures when running the build locally

[Numpsy]

Hi

I'm not sure if this is down to my environment or is an actual issue (I'm running on Windows and I see the CI is running on Ubuntu), but when I run the build script locally I get this unit test failure:

I got this when trying to do a local build for #277 and it prevented the later tests from running, making it harder to test.

Any ideas?

Thanks
