OSError: [WinError 126] The specified module could not be found

This occurred with scipy 1.5.2. Downgrading to scipy 1.4.1 fixes the problem.

TODO Update the requirements.txt with the working version of scipy

Appears to have been reported in scipy scipy/scipy#12400. Even though it suggests that this has been fixed in 1.5.1 neither 1.5.1 or 1.5.2 of scipy fix the issue. Downgrading to 1.4.1 is still currently the workaround
