silence warnings completely

When running this I get a lot of warnings which makes it hard to read my own output

It’s warnings along the lines of

(pid=22798) UserWarning: Distributing <class 'numpy.ndarray'> object. This may take some time.

I have tried

import warnings
warnings.filterwarnings("ignore")

but that didn’t work.

Is there any parameter or env var which could silence all these?

Thanks

@pyrito I think we shouldn’t have an optional setting that’s just a wrapper around a ray init option (log_to_driver=False). I think we should close this issue for now. If we hear that more users want to suppress warnings, we can consider either always setting log_to_driver=False or adding a section about that option in the documentation.

P.S. We may end up setting log_to_driver=False anyway, depending on what happens in https://github.com/ray-project/ray/issues/28216. It might be the way to get rid of ray error spam that I find really annoying when using Modin.

@mvashishtha is there anything more we can do from our end? I can think of trying to add an easily configurable option with modin.config that will suppress warnings at the Ray level, but I’m not sure if that’s something we want to go with.
