Error while finding module specification for 'astrometry.util.image2pnm'

[Ashish Kumar Mandal]

Hi all,

Recently I have installed astrometry on ubuntu 20.04. When I tried to solve a field I see the following errors. Please anyone can suggest on this error.

Reading input file 1 of 1: "apod4.jpg"...
/usr/bin/python3: Error while finding module specification for 'astrometry.util.image2pnm' (ModuleNotFoundError: No module named 'astrometry.util')
augment-xylist.c:590:backtick Failed to run command: /usr/bin/python3 -m astrometry.util.image2pnm --infile apod4.jpg --uncompressed-outfile /tmp/tmp.uncompressed.mPheQR --outfile /tmp/tmp.ppm.rTgpTT --ppm --mydir /usr/bin/solve-field
 ioutils.c:567:run_command_get_outputs Command failed: return value 1

Regards,

Ashish

What is the full solve-field command you are running?

Did you install from the source code, or from the Ubuntu package?

cheers,

Bringing this back to the mailing list...

Can you please add a "-v" to your solve-field command to get more verbose logging.

The "image2pnm" script is supposed to be able to find the python code itself.  What happens if you run "image2pnm", or "/usr/bin/image2pnm"?

And what about "set | grep PYTHON"

As the error message says, python is not finding the astrometry.util module.

Depending on how your PYTHONPATH environment variable is set, sometimes python can get confused if there is a directory named "astrometry" in your current directory... eg if you're still in the astrometry.net source directory.  So try

cd

solve-field ~/Documents/PhD/Telescope_Automation/apod4.jpg

> It works when I run the command 'solve-field /home/ashish/Documents/PhD/Telescope_Automation/apod4.jpg' in the directory-'/home/ashish/astrometry.net-0.95', where 'util' folder is present.

> How can I set path so that code will automatically pick up the util from its position.
