Turning off ConfigurationItems

I am doing some calculations involving propagation of uncertainties, and I keep getting a lot of useless information logs about correlated uncertainties being unsupported. I already know that, I don't care, and I would like to stop it printing these messages.

According to the documentation, it can "be disabled via the WARN_UNSUPPORTED_CORRELATED configuration item"

I can't figure out how to do that. How can I stop printing these unhelpful messages?

Solution

  • See http://astropy.readthedocs.org/en/latest/config/index.html.

    From there you can disable in your astropy.cfg:

    [nddata]

## Whether to issue a warning if NDData arithmetic is performed with
## uncertainties and the uncertainties do not support the propagation of
## correlated uncertainties.
warn_unsupported_correlated = False

    Or by code:

    >>> import astropy.nddata
>>> astropy.nddata.conf.warn_unsupported_correlated = False
