Hello - I upgraded to Pro to 2.4 yesterday and lo and behold my python scripts for overwriting feature classes using the FeatureClassToFeatureClass_conversion tool no longer honors the arcpy.env.overwriteOutput = True environment setting. A whole bunch of my data management scripts depend on this! The script now keeps telling me that my feature class already exists. Of course it does, I'm doing an overwrite. Or at least I did. This was working just fine at 2.1, 2.2, 2.3.x I can't use Copy for most of my layers because I don't want bring over (in some cases) dozens of related tables.... Example: # Import system modules import sys , os , arcpy , time , smtplib from datetime import date , timedelta from arcpy import env # Local variables... message = "" current_time = time . asctime ( ) todaysDate = date . today ( ) priorYear = str ( todaysDate - timedelta ( days = 547 ) ) #547 starting_time = time . time ( ) arcpy .

ArcGIS Pro at 2.4/arcpy- FeatureClassToFeatureClass_conversion does not honor overwriteOutput env setting

Hello - I upgraded to Pro to 2.4 yesterday and lo and behold my python scripts for overwriting feature classes using the FeatureClassToFeatureClass_conversion tool no longer honors the arcpy.env.overwriteOutput = True environment setting.

A whole bunch of my data management scripts depend on this!

The script now keeps telling me that my feature class already exists. Of course it does, I'm doing an overwrite. Or at least I did.

This was working just fine at 2.1, 2.2, 2.3.x

I can't use Copy for most of my layers because I don't want bring over (in some cases) dozens of related tables....

Sometimes a file lock might do it, so you can check to see if the output featureclass exists 'AND' overwriteOutput is True and if they both are, try a Delete.... If it won't delete, then you have other issues.

DavidColey

I appreciate the response. Executing the Delete is not an issue and I can easily do that. However, I shouldn't have to the python 3.16.8 IDLE should honor the environment setting and it's not. That is the issue.

DavidColey

My mistake - the idle is honoring the setting:

So will delete work? (inconvenient or not) even if the overwrite is working? Or will it not delete?

If it will delete and not overwrite, then that is something that should be reported to tech support.

Python wouldn't even be the issue.

Change the 'arc_pro' portion to match your installation path. You can compare the version of python with the version of 'arcpy'

The paths should jive, unless there is a cross-over between arcpy and python in your setup

DavidColey

Ok thanks for the info

mstranovsky

I got it fixed....honoring overwrite now

Get Outlook for Android<https://aka.ms/ghei36>

BryanLiu

I have the same problem.

sys.executable
'C:\\Users\\myname\\AppData\\Local\\ESRI\\conda\\envs\\myenv\\python.exe'
arcpy.__path__

['C:\\Program Files\\ArcGIS\\Pro\\Resources\\ArcPy\\arcpy']

How did you fix it? Thanks.

DavidColey

This never did get fixed. The solution is to delete the feature classes first.
