ImportError: PyCapsule_Import could not import module "datetime"

Hello, I have been running some scripts for a while without issue. Even after upgrading to ArcGis 3.1.1

Now, started receiving this error at random times in the code:

(this error shows it occurred in CopyFeatures, sometimes it happens during other functions)

Fatal Python error: InitDatetime: Could not import datetime C API
Python runtime state: initialized
ImportError: PyCapsule_Import could not import module "datetime"

Current thread 0x000025ac (most recent call first):
File "C:\Program Files\ArcGIS\Pro\Resources\ArcPy\arcpy\geoprocessing\_base.py", line 512 in <lambda>
File "C:\Program Files\ArcGIS\Pro\Resources\ArcPy\arcpy\management.py", line 4690 in CopyFeatures

installed:
Conda version is 4.1.4
Base Python on machine is 3.11
PyCharm 2021.1.3 (Community Edition)

Tried the following:

1. uninstalled:

   ArcGIS Pro
   Pycharm
   Python

2. removed any lingering folders for:

ArcGIS Pro
pip cache

3. re-installed all 3 (from 1)

Been working with ArcGis for about a year now, still learning. Any guidance on this would be appreciated.

arctoolbox functions like CopyFeatures would be expecting arcpy based on python 3.9.18, your base

...Base Python on machine is 3.11...

if you are working in different python versions, are you switching back to an arcpy/arcgis happy environment first?

Hi Dan, Thank you for the response,

I currently only work with the ArcGIS Python so the interpreter is set to Conda environment pointing to the arcgispro-py3 env.

.Base Python on machine is 3.11...

came from your error message, do you have other python versions installed?

Hi Dan,

I only have python 3.11

Re: ImportError: PyCapsule_Import could not import module "datetime"

DanPatterson — Mon, 04 Dec 2023 21:12:40 GMT

you have arcgis pro installed, hence you should have python 3.9,18 installed as well

"C:\Program Files\ArcGIS\Pro\Resources\ArcPy\arcpy\management.py", line 4690 in CopyFeatures

arcpy is built against 3.9.18

Rob24 — Mon, 04 Dec 2023 21:21:47 GMT

Dan, I can uninstall python 3.11 and go grab 3.9.18 .

I'm wondering if this explains why sometimes it would actually run fine and other times just error out (erratic behavior) .

That would be useful and I would recommend a complete reinstall of Pro if you use it mostly

Don't be worried about the title, the procedure is what is important

Problem: ArcGIS pro Freezes on the Initializing Screen before the Sign in Dialog Box Displ (esri.com)

Thank you Dan!, I will try this route and report back.

Update: still having the same issue. I installed ArcGIS 3.1.1 (without installing Python separately). and the error keeps coming back to CopyFeatures.

in the pycharm terminal:

python --version
Python 3.9.16

I know you mentioned arcpy was built against 3.9.18 so I don't know if this is now the issue.

still do not understand why these same scripts where working for months and without changes or updates and started getting this error.

either way, thank you for the help @DanPatterson I appreciate it!

Tech Support would be your best option if you removed all python, pycharm and Pro installations.

There is little use in installing 3.1.1 if you are having problems

Pro 3.2 uses 3.9.18

Good luck

Hi Dan, that is my next step, appreciate your time!

Good morning!
I have a similar problem!
I created a script from the export of an ArcGis Pro model, using Python from ArcGis Pro 3.2 (Python 3.9.18 [MSC v.1931 64 bit (AMD64)] on win32), recently installed.
When executing the script, the message appears when executing the command: arcpy.conversion.ExportFeatures
ImportError: PyCapsule_Import could not import module "datetime"

If anyone has an idea on how to solve it....
Thanks!

copy the script here so people can see what might be causing the issue

Sorry, I don't have permission to share the code.

A part of the command that generates the error:

print ("select by location camada realizado") # Process: Export Features (Export Features) (conversion) Incidentes_filtrado = "in_memory\\Incidentes_filtrado" arcpy.conversion.ExportFeatures(in_features=incidentes_Layer1, out_features=Incidentes_filtrado, field_mapping="uuid .....

Thanks foo your time!

You will have to contact tech support. There isn't enough information to decipher a possible cause with what is given
