ArcGIS Server Py3 - <type 'exceptions.ImportError'>, ImportError('No module named arcgis',), <traceback object at 0x00000000025870C8>

Question

I have cloned the default python env that installs with ArcGIS Server using conda create in the python command window using:

conda create --clone arcgispro-py3 -p"C:\Program Files\ArcGIS\Server\framework\runtime\ArcGIS\bin\Python\envs\py3_envclone2"

I activated the cloned env and installed jenkspy

(py3_envclone2) C:\Program Files\ArcGIS\Server\framework\runtime\ArcGIS\bin\Python\envs\py3_envclone2>conda install -c conda-forge jenkspy
Fetching package metadata ...............
Solving package specifications: .

# All requested packages already installed.
# packages in environment at C:\Program Files\ArcGIS\Server\framework\runtime\ArcGIS\bin\Python\envs\py3_envclone2:
#
jenkspy                   0.2.0            py37hcc03f2d_1    conda-forge

I then spun up the python console using python.exe in command window and then tested imports of my modules without fail:

>>> import arcpy
>>> import jenkspy
>>> import json
>>> import arcgis
>>>

However, when I run from my script:

# need to call pyhton from the environment where ArcGIS allows third party library installs to access all the necessary modules in the script

import sys
    
sys.path.append(r'C:\Program Files\ArcGIS\Server\framework\runtime\ArcGIS\bin\Python\envs\py3_envclone2')
    
# import remaining modules
    
import arcpy, json, jenkspy, arcgis

I get this error:

Traceback (most recent call last): File

"C:\Desktop\MyScript.py", line 10, in <module>
    import arcpy, json, jenkspy, arcgis
ImportError: No module named jenkspy

What am I doing wrong?
