[BUG] replace combine with itertools product#253
Conversation

@fkiraly we've been getting lots of failures on setup in macos and windows like this: https://github.com/dswah/pyGAM/actions/runs/19465120143/job/55698192192 they all complain about codecov. |

Honestly, I have no idea what is going on with codecov, or why moving it to the end would change anything - sorry. Do the search engines or AIs say anything useful about these errors? |

Do you think it might be beneficial to parallelize this for loop? I can create an issue/PR if that might be interesting.

Hey @ankurankan I think that would be great!
Do you think it will run faster?
I have never been very good art parallelizing numerical python routines. My parallel routines always seem to run just as fast/slow as my serial ones...

I can give it a quick try and share some benchmarks. Let's see if that improves anything. Have created an issue: #406

for large search-spaces, gridsearch can easily exhaust all available memory before fitting a single model.
This is because the method tries to pre-determine the entire search space in memory.
we could instead use a generator like
itertools.productthis fixes #242
