Import arcpy and Windows Task Scheduler

RobertKnapik — Sat, 18 Aug 2018 15:58:59 GMT

I have problem with Task Scheduler in Windows Server 2012. I would like to run script in Task Scheduler in which I use arcpy. Unfortunately when I use arcpy in my script Task Scheduler does not work correctly.

I have following test script which print current Python version:

   import platform
   import os
   import sys
   import datetime
   import arcpy
   filename = os.path.join(os.path.dirname(sys.argv[0]), 'plik.txt') #zapis do folderu ze skryptem
   fid = open(filename, 'a')
   fid.write("\nhello\t")
   fid.write(platform.python_version())
   fid.close()

When I delete line with "import arcpy" everything is ok.

Does anyone know how to solve this problem?

According to what you described about problem, it's likely the failure of loading the arcpy module is the cause. I would suspect that you have multiple python interpreters installed on your machine, and the one you are using to run the script does not have arcpy in its system path.

You can print out the system path and visually check it.

import sys
from pprint import pprint

pprint(sys.path)‍‍‍‍

If this is the case, you can add the path of your arcpy module in the PYTHONPATH environment variables settings. Or, you simply append or insert the paths in your script to make it an application level setting.

sys.path.append('<Pro home folder>\\bin\\Python\\envs\\arcgispro-py3')
sys.path.append('<Pro home folder>\\bin\\Python\\envs\\arcgispro-py3\\lib\\site-packages")

I can import arcpy in Python Command Prompt and Python 3.6.5.

I used Python Command Prompt and Python 3.6.5. and something like this was printed:

I can import arcpy in Python (Command line) and Python 2.7.14. I used Python (Command line) and Python 2.7.14 and somtehing like this was printed:

I would like to run my script in Task Scheduler in Python 3.6.5 because in this script I use arcpy and ArcGIS API for Python.

Not sure what else can cause the problem. can you share the settings in your task scheduler?

A quick search gave me this link, hope it helps.

It seems to me that settings in my Task Scheduler are rather ok. I tried everything.

Re: Import arcpy and Windows Task Scheduler

RobertKnapik — Mon, 20 Aug 2018 07:47:48 GMT

I tried again and I noticed that the problem is only then I use python 3.6.5.

In following examples Task Scheduler does not work corectly unless I remove line "import arcpy" from script (test.py):

I also tried to use propy.bat, but the result is the same.

When I use following settings Python 2.7.14 runs and Task Scheduler works correctly even with "import arcpy" in script:

(but I have to use Python 3.6.5 because I use also ArcGIS API for Python in my script )

What version of Pro do you have installed on this machine?

Re: Import arcpy and Windows Task Scheduler

simoxu — Tue, 21 Aug 2018 00:34:13 GMT

Please be aware that arcpy is licensed.

the script needs to be authorized to run outside of Pro.

See the Authorizing Python outside the application part in the following document:

MichaelVolz — Tue, 21 Aug 2018 16:22:36 GMT

Does this authorization requirement exist for both Named User and Concurrent Use licensing in Pro?

I solved the problem. I repaired the ArcGIS Pro installation and everything is ok.
