I'm trying to use Cython. I use setup.py and build as opposed to letting pyximport do this. However, every time I import my module it seems pyximport is called. Pyximport fails to build and everything crashes.
I use Spyder. I do not have a single reference to pyximport in my project, but Spyder does not seem to care and keeps calling pyximprot.
I called my program from the command window (outside Spyder) and it ran just fine.
How can i get rid of the call to pyximport? Or is something else going on?

The problem appeared in Spyder because the package's initialization actually loads pyximport and calls pyximport.install(), in the file utils/site/sitecustomize.py.
Other have complained about it on GitHub:
A solution that is not elegant (will not survive updates of spyder, for instance) but that should work is to manually edit the sitecustomize.py file in your spyder installation and remove the section under if HAS_PYXIMPORT:
(Spyder maintainer here) This problem was fixed in our 3.2.8 version, released on March 2018.
