Arcpy needs to run within active ArcGIS Conda Environment

[cyrusblankinship]

My issue started the same as #10, where it was saying

Widget Javascript not detected. It may not be installed properly. Did you enable the widgetsnbextension? If not, then run "jupyter nbextension enable --py --sys-prefix widgetsnbextension

I uninstalled and reinstalled both packages

conda uninstall -c conda-forge ipywidgets
conda uninstall -c esri arcgis

conda install -c conda-forge ipywidgets
conda install -c esri arcgis
jupyter nbextension enable --py --sys-prefix widgetsnbextension

but that made everything worse. I am now getting an error saying

arcpy must be run from inside the Conda environment, which ArcGIS
uses to manage the installation of Python.
You can access this environment by launching Python from the links inside the
"ArcGIS > ArcGIS Pro" Start Menu Group:
"Python Interactive Terminal" starts a Python session.
"Python Command Prompt" opens a Command Prompt window initialized with Conda.

It appears that you've installed arcgis package in arcgispro-py3 environment using proenv.bat/Python Command Prompt window within ArcGIS Pro, but the notebook server has been started in a different conda environment.

Can you try restarting Jupyter notebook from within the proenv.bat/Python Command Prompt window in ArcGIS Pro?

Hello @cyrusblankinship,

Unfortunately the instructions in the other thread are out of date and using conda-forge is known to cause some issues. We've resolved this problem for the next release of Pro, but that doesn't help you now. A couple of options:

1. If you're comfortable editing code, open the file:

<Pro installation directory>\Resources\ArcPy\arcpy\__init__.py

and change line 31, which currently reads:

if not "Continuum" in sys.version:

to instead read:

if not "Continuum" in sys.version and not "conda-forge" in sys.version:

That will allow "conda-forge" to pass muster as a provider of a Python installation. (We added this check to prevent some complicated cases that will cause crashes with mixing Python installs).

2. The less technical solution is to entirely delete Pro, remove any remaining directories and files in the <Pro install>\bin\Python directory (which will have been modified by installing via conda-forge), and then installing Pro again. Finally, then use the instructions provided in the documentation which should boil down to opening proenv.bat and then running:

conda install -c esri arcgis

From the prompt.

@scw, I followed the second option and it worked. Thank you both for the detailed description.
