Module not found error

Question

Hey! I'm parcially new in programing and currently I am making a script in Python for ArcGis Pro. This script has to convert coords from WGS84 to UTM, globally of course. For said cript I started using a library named 'utm' and until then didn't had any problem either with syntax nor the functions from python or arcgis. But when I went to run the script it showed me the error among the words of 'module 'utm' not found'. So I checked thee possible reasons for it and ended up modifying the Enviroment, Path, cheking the python installation and version and the library installation (via PIP) but no joy.

If anyone knows or had this same problem and solved it please let me know.

Thanks in advance!

A basic arcgis pro environment will be

C:\...install folder ...\bin\Python\envs\arcgispro-py3

packages, like utm should be in

C:\...install folder ...\bin\Python\envs\arcgispro-py3\Lib\site-packages

The python executable and where python will look for packages can be determined using the sys module

import sys

sys.executable
'C:\arc_pro\bin\Python\envs\spyarc\python.exe'

sys.path
['C:\arc_pro\Resources\ArcPy',
 'C:\arc_pro\bin\Python\envs\spyarc\python39.zip',
 'C:\arc_pro\bin\Python\envs\spyarc\DLLs',
 'C:\arc_pro\bin\Python\envs\spyarc\lib',
 'C:\arc_pro\bin\Python\envs\spyarc',
 '',
 'C:\arc_pro\bin\Python\envs\spyarc\lib\site-packages',
 'C:\arc_pro\bin',
 'C:\arc_pro\Resources\ArcToolbox\Scripts',
 'C:\arc_pro\bin\Python\envs\spyarc\lib\site-packages\win32',
 'C:\arc_pro\bin\Python\envs\spyarc\lib\site-packages\win32\lib',
 'C:\arc_pro\bin\Python\envs\spyarc\lib\site-packages\Pythonwin',
 'C:\arc_pro\bin\Python\envs\spyarc\lib\site-packages\pywin32security',
 'C:\arcpro_npg\npg',
 'C:\arcpro_npg']

In the above example the last two lines are paths I have added for extra packages, .... you can add to the path, as I did, or install your package in the listed site-packages folder in your environment.  In my case Pro is installed in the c:\arc_pro folder

Thanks for your reply! Here's the script; I checked the folder of the enviroment and 'utm' it's there, but in a 'blank' format when the rest are a .exe file.

I look foward to your Reply, thanks.

was 'utm' installed in the python environment that Pro uses?

check in the site-packages folder of your environment to see if it is installed there.

Also show your script in case it is a scripting error
