Get rid of the `setup_requires` as that has been raised as a concern. Instead simply raise an informative error and exit. This way it is up to users to address this reasonably somehow.

Happy to defer entirely to you on this one :) |
This reverts commit 33c8868.
As we have only explored Cythonizing one function here and it is not as critical as Cythonizing the Scheduler, go ahead and skip this module for now. We can always add it back later.

As the modules we Cythonize are
.pyfile, both the compiled extension and the.pyfile get installed. On macOS and Linux, this doesn't appear to present an issue as the.sowill be loaded before the.pyfile. So the.pyfiles are effectively ignored on these platforms. However it seems Windows loads the.pyfile before the.pyd(Windows compiled extension).To fix this, we make some tweaks to the build process. Namely we rename the
.pyfile to a.pyxfile, which exclude from packaging (just as we exclude the.cfile Cython generates). Thus we avoid having two files with the same name and different file extensions, which may be loaded in arbitrary order. We make sure to return the source directory to the original state by reverting the renaming when we are done.For this to work effectively on CI, we start installing into the Conda environment instead of doing an editable install. This way we know only the compiled extension was installed.
