How to suppress warning about color calibration

Coding

How does one suppress this warning, which is output to the terminal each time I run a task?

10.8500 	WARNING 	This monitor has not been color-calibrated. Using default DKL conversion matrix.

I’m not worried about color calibration, but would like to use the DKL colorspace. Thanks!

Same question here, unfortunately:
warnings.filterwarnings(“ignore”)
does not seem to work.

Psychopy complains because you are not supplying a conversion matrix from DLK to RGB.

See here in the source code:

So, perhaps you can prevent the warning by supplying the “default conversion matrix” upfront.

    # ... code above
    
    my_monitor = monitors.Monitor(name=MONITOR_NAME)
    # for `conversionMatrix`, see:
    # https://github.com/psychopy/psychopy/blob/148c730ccea10cb2183fdc94e843e278604b49ca/psychopy/tools/colorspacetools.py#L416-L421
    conversionMatrix = numpy.asarray([
        # (note that dkl has to be in cartesian coords first!)
        # LUMIN    %L-M    %L+M-S
        [1.0000, 1.0000, -0.1462],  # R
        [1.0000, -0.3900, 0.2094],  # G
        [1.0000, 0.0180, -1.0000],  # B
        ])
    my_monitor.setDKL_RGB(conversionMatrix)

    # ... continue code

I haven’t tested this myself.
