Installed cmlib-1.1.3 and we're back in business!

Thanks for the prompt assistance. Argos is my favourite NetCDF viewer, everything you need and nothing you don't.

Which Argos and library versions do you have? Can you please copy/paste the versions from the about box?

Can you somehow give me access to this file?

Looking at the error, it seem to me that this error is related to reading the color maps. What happens if you select a different color map by clicking on the color map selection dialog. See red circle in screen shot.

I'm unable to choose a different colourmap as the error is fatal (unless I can manually put this in the setting configuration somehow?). cmlib is also yours right!?

With QT_API=pyside2 python3.9 -m argos filename.nc I'm able to keep the GUI open, although the Exception trace is still the same on all the color map fields.

Yes cmlib is also mine.

So does this error occur only for that specific file? Or does it occur with any file?

What happens if you run the cmlib_demo command? See here

I get the same error, so that ties it down to something in cmlib. Are you happy to continue discussing here?

Yes we can continue discussing here. I can try to reproduce it later this evening.

Do you use Linux or MacOS?

Accidentally pressed the close button a bit too early, but I have fixed the issue. I could reproduce it when I upgraded Numpy to version 1.23.1. It was an easy fix.

I have made a new release of cmlib: version 1.1.3. If you update to that version it should work. Please let me know if it doesn't.
