import pywapor takes a very long time

[Alexander Kalinovsky]

Hi,
import pywapor

The import time for the pywapor module takes too long: 1-1.5 minutes.

I quickly looked at the nested imports: it seems there are no imports with lengthy operations.
Perhaps this is all due to poorly cyclical imports?

What could be the problem?

python 3.10.*

Not sure, if you have any suggestions on how to improve import time please let me know.

I think the problem is using numba for optimization. Profiling showed that 95% of the time is spent calling call and essentially compiling the entire project code.

If you comment out all the decorators from numba like @jit and so on, then import will take ~1sec

Hi Alexander, thanks for letting me know. I guess we could try to import those decorated functions when they are actually needed, instead of importing them at the start.

pywapor.enhancers.smooth.core is now imported when its functions are actually required, resulting in a much faster import pywapor.
