Caching of images

[tmct]

Hi, the Caching features are very useful for my expensive functions. I also find the mo.image(url) feature very helpful. But I can't see a way to use them together.

What should be the way that users specify caching for URL-sourced images? Should there be caching features in mo.image() itself, or should it be the responsibility of the user to just download the image then wrap it in a cache?

Thanks,
Tom

Hey Tom- glad you are getting use out of caching.

Here's a super straight-forward way of doing this:

image_cached = mo.cache(mo.image)

image_cached("https://upload.wikimedia.org/wikipedia/en/b/b6/Dramatic_Chipmunk.png")

Key thing to remember is cache just captures the compute but not outputs. You could also do:

with mo.cache("my_image"):
    img = mo.image(...)
img

Hope that helps!

Ah, apologies! I hadn't realised that fully-featured marimo objects like the output of mo.image would Just Work with mo.cache. I'll set that up now. Many thanks.

Will try that out and let you know, for completeness, but this should solve my problem

On first attempt it seemed like it was still downloading image every time, but it's likely I was doing something wrong - I'll try again later in the week when I get more time

This is indeed working - no idea where I went wrong the first time... Thanks again!
