Workaround: installed package crashing Pro 1.4.1

ClintonDow1 — Wed, 31 May 2017 18:17:57 GMT

There have been a few reports of Pro 1.4.1 crashing after packages which depend on the Jupyter/pyQT packages are installed via conda. This is due to a problematic DLL that shipped with conda which doesn't meet PEP 384. It is easy to fix, simply by deleting or renaming the culprit DLL in your active Pro environment's folder.

In your %ProInstalDir%/bin/Python/envs/arcgispro-py3 folder (or equivalent if you have created additional environments), delete or rename Python3.dll - many people are hesitant to alter DLL files, but in the same folder you will see Python35.dll - this is the one which should be loading and will fix the issue. Once this file has been removed, reopen Pro and it should work as expected.

This issue has been identified and fixed for Pro 2.0 and will not be a problem going forward. If you continue to experience issues please post to this discussion for additional support.

I was having issues with Pro crashing when trying to access a custom script tool and other tools in the Geoprocessing pane. This workaround corrected the issue as ArcGIS Pro is no longer crashing when I try to access the script tool.

What was interesting, though, is that my Python3.dll file was dated May 15, 2017, but the issue only started presenting itself in the last few days.

That was the date that the .dll was compiled for the package which was causing the issue, not necessarily when it was installed in the env.

I used the suggested workaround (deleted dll file), and it stopped Pro from crashing, so thank you for that, but I ran into an issue importing pandas in the console, and I wonder if that might be related.

I tried

import pandas

and received the following error:

Runtime error
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\pandas\__init__.py", line 39, in <module>

File "C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\pandas\core\api.py", line 20, in <module>
from pandas.core.reshape import (pivot_simple as pivot, get_dummies,
ImportError: cannot import name 'pivot_simple'

I would appreciate any information on the matter.

Good morning Mike,

I just tried to replicate this on a fresh install of 1.4 but was unable:

- Installed 'arcgis' package (installs Python3.dll)

- Error as described above

- Deleted Python3.dll

- Reopened Pro, no error

- 'import pandas' in the Python console in Pro & in python via cmd prompt both imported successfully

I currently have pandas 0.20.1 installed, is yours a different version number?

It may also be another package preventing pandas from updating. My 'conda list' shows:

Thanks for the response! I think I had the same version of pandas, but some

of my other packages might have been out of date. I wound up

uninstalling/reinstalling and now everything is working fine.

I find myself with the same issue. I am running pandas 0.20.3. and ArcGIS pro 2.0. "Import pandas" in Python yields:

Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
import pandas
File "C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\pandas\__init__.py", line 39, in <module>

from pandas.core.reshape import (pivot_simple as pivot, get_dummies,
ImportError: cannot import name 'pivot_simple'

I have uninstalled and reinstalled arcgis pro. Attempted to remove or uninstall pandas using conda. I have tried to find a python3.dll, however it is not as described in the discussion above.

Conda List shows two installs of Pandas 0.20.3 along with a few others.

With the way the installer currently works, if you modify files within the Pro folder (ie by updating them with conda) then it won't remove those files when uninstalling. This is because the file hash has changed. So you're seeing two versions of pandas likely because when you reinstalled it laid down an older version beside the updated one that wasn't deleted.

Its an annoying problem and we're finding ways around it for upcoming versions. Currently you may have to manually delete the %pro%/bin/Python/envs folder when uninstalling to ensure everything is cleaned up, or manually remove that pandas version from the environments lib/site-packages directory.
