Quick and dirty caching of function results on disk using pickle
The name stands for pickle cache, and it is a quick and dirty way of caching function results on disk using
This can be helpful for example in some machine learning tasks, where you have to preprocess the data with many time-consuming steps, and you want to not recompute things every time you run your program.
from pklcache import cache @cache("foo_result.pkl") def foo(*args, **kwargs): # time consuming operations here... return result
If you run the program
result = foo() #foo executed
And if you run it again
result = foo() #foo not executed, load result from disk
The first time
foo is called its result is saved on disk on
foo_cache.pkl. If then the function is called another time or the program is run again,
foo is not executed, instead its return value is loaded from disk and returned.
fpath: is the cache file path
Falsethe store/load is disabled and the function is executed like if it wasn't decorated. Useful during development and debugging.
pip install pklcache
If you don't want an external dependency just copy and paste the code in __init__.py
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
