- MNE version: 1.4 - operating system: macOS 13.4 I am running some code with `raw.compute_psd` with option `n_jobs=16`. I am getting the output: ```python [Parallel(n_jobs=16)]: Using backend LokyBackend with 16 concurrent workers. [Parallel(n_jobs=16)]: Done 5 out of 16 | elapsed: 1.9s remaining: 4.2s [Parallel(n_jobs=16)]: Done 9 out of 16 | elapsed: 2.0s remaining: 1.5s [Parallel(n_jobs=16)]: Done 13 out of 16 | elapsed: 2.0s remaining: 0.5s [Parallel(n_jobs=16)]: Done 16 out of 16 | elapsed: 2.1s finished ``` How do I suppress this output? I tried `verbose=0` inside the `compute_psd` function. I also tried to put the computation inside a `with joblib.parallel_config(verbose=0):`, but no success. Thank you for your help! ---

```python import mne sample_data_folder = mne.datasets.sample.data_path() sample_data_raw_file = (sample_data_folder / 'MEG' / 'sample' / 'sample_audvis_raw.fif') raw = mne.io.read_raw_fif(sample_data_raw_file, verbose=False, preload=False) spect = raw.compute_psd(n_jobs=12, verbose=False) ``` When I run this on current main I see no joblib output. The problem is passing `verbose=0` instead of `verbose=False`. “truthy” and “falsy” values won’t do what you expect here, because underlyingly verbose is a system of integers/strings, and we use `True` and `False` as aliases for specific integer levels. See the table here: [Configuring MNE-Python — MNE 1.4.2 documentation](https://mne.tools/stable/auto_tutorials/intro/50_configure_mne.html#logging) ---

Thank you! However it is also removing the information like: > Effective window size : 8.000 (s) But that’s something I would like to keep. Is there some way to only remove the joblib output without removing the mne output? ---

Not presently (at least not that i can see). @larsoner WDYT about this? one reasonable approach might be a config value (`MNE_JOBLIB_LOGGING_LEVEL` or so) that can be set separately from the global logging level. ---

Yes, 2 different verboses options/configs would be great I imagine… ---

Sounds good to me. We could add it to `set_log_level` and `use_log_level`, and have the default `joblib_verbose=None` mean “use the `verbose` level” (which would preserve backward compat) ---

@chapochn would you be up for making a PR to implement this? If not, please open a GitHub issue linking back to this thread, so that we don’t lose track of the request. ---

I’ll just open an issue for now! ---
