GUI cannot load variable

[painter1]

Run the UV-CDAT GUI, e.g.
uvcdat --output=""
In the variable window (upper-right), click on the "+" to add a variable. Browse for a suitable NetCDF file. Choose a variable. Click on "Load". Then (with a UV-CDAT which I built earlier today) you get an exception in a popup window:

I'm running into this error when trying to test my merged branch. Has anyone fixed this yet?

I think @remram44 is getting close, but once it failed once I think you might have to remove your .uvcdat directory to "fix" it. Not positive about it but it's worth a try.

Looks like this is caused by the uvcdat_cdms package not being loaded, I assume because of a previous error. I can't tell from this log.

i think CDAT/VisTrails#14 and CDAT/VisTrails#16 fix this. You probably need to remove your .uvcdat though.
