How to disable print_summary for failed fits so that multiprocessing in sklearn works properly?

[braza2]

Hi,
I have a problem, where after failed fits lifelines prints a summary. However, due to this printing, I can't properly make use of multiple cores while doing hyperparameter optimization with sklearn RandomizedSearchCV. Is there a way to stop any output to stdout, stderr?

There may be a Python solution to redirect stdout, but I'm curious: what is being printed when a job fails? I should change it to put msgs in the Exception

this is whats being printed:

Ah, I do some printing when it fails. This information should be in the error message. https://github.com/CamDavidsonPilon/lifelines/blob/master/lifelines/fitters/__init__.py#L1963-L1966

There's currently no way to suppress this, you'd have to make a modification on your end
