reloading a cython module

[Kireet Reddy]

Is there a way to reload a cython module in a running python process? I have some code that takes awhile to load up some data on startup, so it would be much easier if i could just reload the code instead of having to reload the data again to test changes. I've tried pyximport and importlib.reload with no luck. I have a full description of the problem here:

It's not a Cython issue per-se -- you can't reload compiled extensions at all.

Can you find a way to cache the data / store it in a more compact efficient way to make loading it faster?

Final kludge -- I think pyximport does a hack where it doesn't actually reload a module, but rather, loads a new one, and "hides" the old one. This means that if you did this for along time, it would keep piling up a bunch of old modules, but a few exrtras lying around won't hurt.

So you could do a similar kludge, or maybe use pyximport:
