FIX: short-circuit n_jobs=None to n_jobs=1 without Parallel setup by skjerns · Pull Request #13777 · mne-tools/mne-python

skjerns · 2026-03-22T21:32:40Z

What does this implement/fix?

As laid out, when a parallel function is prepared using n_jobs=None, it runs the complete parallel function setup including a file read. This creates overhead that is unnecessary. It should be safe to only check whether there's another n_jobs overwriting it via a context manager and else just set it to 1.

This fix short-circuits the logic: If n_jobs=None it quickly resorts to set n_jobs=1, unless we are in a joblib parallel config.

Hi @skjerns! Thanks for the PR!

I took a quick look at your code and CircleCI errors, and it looks like the n_jobs test function you added is having some trouble. A couple suggestions / refresh points: 1. When we pass a parameter like n_jobs to a test function, we've got to set up an n_jobs fixture so we've got something there to pass in. The other test function in the test_parallel.py file is a good example. You'll need to add the fixture for your test to pass. 2. Generally, a good practice is to run the test files locally to make sure your tests pass on your system, then do your pushes. This just helps us conserve CircleCi resources!

Cheers.

sorry, you are absolutely right 🙈 I tested the code line-by-line locally, but without pytest, and have a habit of testing with CI, I should change that.

Anyway, I think now it's fixed

I think the pip errors are unrelated?

not sure why the azure build fails though :-/ it works locally. Any ideas?

mne\tests\test_parallel.py:73: in test_parallel_func_n_jobs_none
    assert parallel is not list
E   AssertionError: assert <class 'list'> is not list

+    # Test that n_jobs=None inside a joblib context uses Parallel.
+    with joblib.parallel_config(backend="loky", n_jobs=2):
+        parallel, p_fun, n_jobs = parallel_func(fun, n_jobs=None)
+    assert parallel is not list


Not sure why this doesn't work on Windows, but I know there are some quirks there (e.g., this). Maybe for simplicity just skip this test on Windows and add a TODO comment to look into it someday...?

larsoner · 2026-03-24T13:37:26Z

... and unrelated pip-pre failures should be fixed by a tiny tweak I put into #13779

…ix_njobs_none

Tests are passing now! Review appreciated :)
