Hi I have seen a number of questions relating to this flowline of using ArcPro python with FME but I cant find a solution for my set up.

 

I have ArcMap 10.8 and ArcPro 2.6 installed in same environment

 

I am using FME 2021 64 Bit. I currently have a lot of workspaces set up to use acrpy for fme feature processing through the python caller. This whole flowline is working for fme and arcmap using 2.7 python.

 

I want to replicate my workspaces to run the same processes using ArcPro with python 3.6 . When I run my workspaces that include python callers I get the following error message immediately on startup

I assume this is the culprit

 

File "C:\\Program Files (x86)\\Python27\\ArcGIS10.8\\Lib\\site-packages\\reprlib\\__init__.py", line 7, in <module>

 

How do I resolve this?

 

I have set the python interpreter and compatibility and PYTHONPATH but still have the same error

 

PYTHON 

I have also set the arc compatibility as Pro

 

Do I need to change something in Python path environment variable?

 

I still want to be able to use FME, arcmap and 2.7 python in the same environment for the forseeable I just want to be able to switch between the python interpreters in FME for when I want to process using FME/Arcpro and python 3.6

 

I thought it would be easier than its turning out to be!

 

Thanks in advance

Hi @ciarab​ 

The most likely cause of the error is the presence of a Python 2.7 directory (eg. C:\\Program Files (x86)\\Python27\\ArcGIS10.8\\Lib\\site-packages) in PATH or PYTHONPATH. Try checking for any Python 2.7-specific paths in PATH and/or PYTHONPATH and removing them.

Note that you do not need to set a custom Python interpreter in order to use ArcGIS's Python. Setting the workspace's Python Compatibility should be sufficient.

@debbiatsafe​ thank you for that, I was hoping it would be as easy as setting the python compatibility.

 

Do you know if  C:\\Program Files (x86)\\Python27\\ArcGIS10.8\\Lib\\site-packages is removed from the python path will that have any impact then on running the workspaces I have configured to run with ArcMap 10.8 and FME 2019.1 with python 2.7

 

I am attempting to migrate a rather large (MASSIVE) flowline to ArcPro its going to take a number of months to complete. Goal then is to have FME integrated with Pro and 3.6 but I am a good way away from that.

 

In the meantime I still want to be capable of running this workflow in ArcMap python 2.7 and FME integrated. So I dont want to break that working process if at all possible . I am working in development environment so at least thats something 😂

Hi @ciarab​ 

You're very welcome.

I don't believe removing  C:\Program Files (x86)\Python27\ArcGIS10.8\Lib\site-packages from the Python path environment variable will make a difference in FME. 

If the Python Compatibility parameter is set to Esri ArcGIS Python 2.7, then this directory is included as a directory to search. You can verify this by printing the search paths:

import sys
print(sys.path)

You should see the same site-package path in the list that is printed.
