image2pnm fails #216

Closed avilqu closed 3 years ago

avilqu commented 3 years ago

The solve-field command fails with the following output:

tan@bobby ~/Astro/science/WASP-41/20210311 RC8 ST402 $ solve-field calibrated/wasp-41_Light_L_150_secs_2021-03-08T02-32-59_033.fits

I have installed the AUR package astrometry.net. The version is "Revision 0.82, date Thu_Jul_16_16:26:352020-0400." (as seen with solve-field --help).

I don't know much about Python environments but it seems that could be the issue here? I use python 3.9.2 and I have installed anaconda too which I use for some image calibration work.

Yeah, like the error message says, it's not finding the 'astrometry' python package. The PYTHONPATH environment variable has to be set so that it contains the python 'astrometry' directory (containing the init.py file, util/ directory, etc). I don't know anything about AUR so I can't speak to where they chose to install files. cheers, --dustin

Thanks for your answer. The PYTHONPATH variable didn't exist on my system so I created it in my .bashrc with the following value:

PYTHONPATH=/usr/lib/python39.zip:/usr/lib/python3.9:/usr/lib/python3.9/lib-dynload:/home/tan/.local/lib/python3.9/site-packages:/usr/lib/python3.9/site-packages:/usr/lib/python/site-packages/astrometry

I'm sur the astrometry folder listed is the one containing the init.py file but I still get the same error. Am I defining my PYTHONPATH variable the wrong way, maybe?

avilqu commented 3 years ago

Alright sorry I had misunderstood the way PYTHONPATH works. I solved it by having only '/usr/lib/pyton/site-packages' as my PYTHONPATH.

Thanks for your help.
