I have been working in the high energy astro server (medium usually) performing fermi analysis with fermipy just fine until today. When I import fermipy doing
from fermipy.gtanalysis import GTAnalysis
I receive
ModuleNotFoundError: No module named 'pyLikelihood'
Which image are you using, the Fornax-hea one or the Fornax-hea_dev one?
I can run that import fine in the fermi environment on the non-dev image.
I confirm what @djturner sees. That command runs in the fermi kernel.
I was not on dev, but on the default high-energy astro. I have been working in this image without problem with fermipy until now. I will try again this morning and let you know.
Rookie mistake. The kernel changed on me 
. It imports fine now. Carry on.
