Speed up import #1948
Comments
I ran the same tests and piped it through tuna, like I did in #1135 and here's a snapshot: I fear that most time is not lost by loading indicators. |
Regarding the load time of indices, what I did is I commented |
Addressing a Problem?
Import takes 2.5s on my laptop.
Benchmark using
python -X importtime test.py
where test.py is just
import xclim
Potential Solution
xclim.indicators
: 0.1 sxclim.indices
: 0.7 sFor reference, here are import times for some of our dependencies. Note that these numbers are only valid in the xclim context, you'd get different results by testing them individually, since they import each other.
Additional context
Code for lazy import (https://docs.python.org/3/library/importlib.html#implementing-lazy-imports)
Note that if we lazy import indicators, then they're not in the xclim registry. So the virtual module creation, which relies on the registry, would need to trigger their import.
