solve-field CLI fails

[Banjoman02]

Encountering an error now every time I try running solve-field.

(odl) mcampbell02@1311-mcampbell:~/projects/ressolve$ solve-field examples/M42_00001.fits Reading input file 1 of 1: "examples/M42_00001.fits"... /usr/bin/python3: Error while finding module specification for 'astrometry.util.image2pnm' (ModuleNotFoundError: No module named 'astrometry.util') augment-xylist.c:591:backtick Failed to run command: /usr/bin/python3 -m astrometry.util.image2pnm --infile examples/M42_00001.fits --uncompressed-outfile /tmp/tmp.uncompressed.FFRPrT --outfile /tmp/tmp.ppm.Ox7oDF --ppm --mydir /usr/bin/solve-field ioutils.c:568:run_command_get_outputs Command failed: return value 1

Attempted uninstalling and reinstalling astrometry.net packing with apt.

Hi,

Usually this sort of thing happens when you have a partially-removed old install and a new one in a different path.

The code runs the "image2pnm" program, which should be a script that runs the python module astrometry.util.image2pnm (setting the PYTHONPATH to a relative path)

It's hard to diagnose the problem exactly, but you can try finding out things like

which image2pnm
image2pnm
dpkg -L astrometry.net
apt search astrometry.net
python3 -c "import astrometry; print(astrometry.__file__)"
python3 -c "import astrometry.util as x; print(x.__file__)"

Eg, here's a similar report that was due to an old partial installation

I am having a similar issue. Running FreeBSD 14.2 and astrometry-0.97_1 from the official FreeBSD repo. Getting:

Only one astrometry packge is installed. Everything was working fine previously before upgrading the package. I would sincerely appreciate any pointers.

Update: Traced this to the following:

% an-fitstopnm -v -i 1.fits
Reading pixels...
Illegal instruction

Update: rebuilt astrometry-0.97 from sources. Problem solved. Everything works fine now. Absolutely zero idea why would it fail when originally installed as a binary from the repo.
