Gain plot error during selfcal

[Ermiasabebe]

After meqtee-pipeliner.py succesful, there is a problem in the gain plots. As a result of this, the script will not proceed. The errors in the log are:

gg = numpy.transpose(sols[j],(xaxis,yaxis))

ValueError: axes don't match array

File "/usr/local/meqtrees/Cattery/Pyxides/stefcal.py", line 186, in stefcal

plotfail("plot routine failed, see exception above");

I saw the script stefcal.py but I couldn't comprehend what the problem is related to my script.

Any suggestion, please?

I also get this error sometimes. We need to chase this down

If you don't anything to do with those plots for the time being.
Obtain a stefcal script in elwood/home/sebokolodi/pipeline/applied-sourcery/stefcal.py

It has those lines commented out. #hides

Cheers,
Lerato

Nothing wrong with a pragmatic solution, but you should report the error as well!

Two problems here, one that the plot failure should have been be reported as a warning and not an outright failure. The warning mechanism itself threw an exception. This has been fixed by ratt-ru/meqtrees-cattery@6ad9285

The other problem is the actual plot failure per se at the dreaded line formerly known as 666. My guess is that there's a null gain solution in there (i.e. one that isn't a matrix) which the code doesn't check for.
