DLL load failed while importing _arcgisscripting with Standalone ArcGIS Scripting Environment in Anaconda

Dear all,
I usually work with a complete ArcGIS Pro installation on an x64-Windows10 machine. I additionally used to script with a Python environment clone created in the ArcGIS Pro GUI, and Spyder started from Anaconda Navigator.
With the recent upgrade to ArcGIS Pro 3.1, I started getting error messages in Spyder last week while importing ArcPy:
ImportError: DLL load failed while importing _arcgisscripting: Das angegebene Modul wurde nicht gefunden.
Although I followed the usual procedure after an upgrade (deleting, copying and activating a new clone in ArcGIS Pro), this did not solve the problem. Based on troubleshooting reports on the web, I tried several modifications then:
- First, I deleted the created clone, cleaned up all temporary files in the User folders of conda and ESRI and created the clone again (with the old and afterwards also with a new name).
- Second, I removed my Anaconda installation and replaced it with a fresh one.
- Third, I removed my ArcGIS Pro and replaced it with a new one.
- Fourth, following this blog post, I removed the clone again and created a new one using the Anaconda Prompt instead of the ArcGIS GUI.
- And finally, I tried to solve this by adding path strings to the system variables "Path" and "PYTHONPATH" (the created environment is called "esri", I did not change the user variables as the paths are user-independent):
- C:\ProgramData\Anaconda3\envs\esri\Lib\site-packages\arcgisscripting
- C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\Lib\site-packages\arcgisscripting
Unfortunately, I was not able to solve it. I also run the DependencyWalker tool on the _arcgisscripting.pyd file in C:\ProgramData\Anaconda3\envs\esri\Lib\site-packages\arcgisscripting getting some error messages:
Error: At least one required implicit or forwarded dependency was not found.
Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.
Error: A circular dependency was detected.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.
I am new to DependencyWalker, but as far as I have seen, the tool cannot tell me directly what I must do to make Python find the _arcgisscripting.pyd file in the created environment.
Right now, I have no idea anymore what I could try next. I do not want to make a new setup of the whole Windows system just because of a missing path string; I hope someone can help me with this...
Here are the code lines and the resulting error message again:
(base) C:\Users\ga98tif>activate esri
(esri) C:\Users\ga98tif>python
Python 3.9.16 (main, Mar 8 2023, 10:39:24) [MSC v.1916 64 bit (AMD64)] on win32

Instead of installing spyder through Anaconda, I'd stick with installing spyder from Pro's package manager because the packages will come from ersi-conda channel/repo first, and not conda-forge. I think you'd get a better dependencies that work with arcpy. You can set the preference and order of these channels, but sometimes the conda will default to what it wants (due to dependencies and what is in your pkg folder), regardless of assignment.
I thought Anaconda came with PyCharm Community so that is a bummer it's Professional, but good to know the issue when spyder is involved. If you are a student or teacher, jetbrains offers free licenses for their IDE's. But, Anaconda also comes with VS Code, so if you are truly stuck in Anaconda maybe try VS Code?
I think the architecture difference between PyCharm and spyder is why spyder has so many issues. PyCharm is built on Java, and is separate from python packages. Spyder is built with/ relies on many of the same python packages that we also use for our code. We may need version 3.1 of a package for our code, but spyder needs 2.8, so one or the other breaks. I could be wrong, but I think it's disastrous trying to coexists for the long term. Maybe some people like having to resolve the environment and spyder every time Pro updates, but I'd rather spend that time working in an IDE that separate, is stable, and only requires pointing to a new interpreter when needed. Life's too short to fight with these things if there are options available.

Isn't conda great? It could also be that the arcpy is not licensed.
Sounds like you have two conda managers on your machine and they may be pulling from different package caches.
C:\Users\u\AppData\Local\ESRI\conda\pkgs and C:\Users\u\.conda\pkgs
They can be installed on the same day, within the same hour and still have different versions of packages and dependencies because conda will do what conda does. So trying to use one package from the other (by including/ setting the path) may not work because of dependency difference. If you haven't cleaned those out and rebuilt them during your cleaning, it might be worth to explicitly do so and install again, get Pro working and its env working, and then add Anaconda Navigator if you need it. You could create a shortcut to spyder once its installed into the environment.

Hi Jeff,
Thank you for your response.
I did not know yet that ArcGIS Pro installs a second conda manager, but you are right: The paths seem to be a hint for this. Nevertheless, I indeed cleaned out all the user-specific folders (envs and pkgs) before re-installing ArcGIS Pro and Anaconda. This worked for one of our IT administrators, but it did not in my case...
Nevertheless, as I had urgent project work to do, it was the faster solution to set-up the whole Windows from scratch again than to search for the missing file/path somewhere in the deep-memory of the PC.
Thank you all for your thoughts!
Best,
Johannes

Update:
I did a complete reset of Windows installing ArcGIS Pro 2.8.3 and Anaconda --> The Python-Clone of ArcGIS Pro worked perfectly with Anaconda/Spyder.
Due to instabilities of some tools (e.g., Pairwise Dissolve) in the ArcGIS Pro version 2.8.3, I tried to upgrade again to ArcGIS Pro 3.1. The result: The tools work great now, but I face the same problems using the new v3.1 clone in Anaconda/Spyder again, so I cannot use the bugfixed tools in stand-alone Python skripts from Anaconda anymore.
Does anybody have an idea, how to solve this issue?
Following this post, I add some information:

Could you try PyCharm as an alternative? There is a Anaconda version you can install in Navigator. Start with a fresh clone, without Spyder, only modifying the cloned env through Pro's manager.

Hi @Anonymous User,
thank you for the idea. For a better understanding I summarize my Python environment clones:
- base = original Anaconda environment created while installing Anaconda (from here called "Anaconda-environment")
- arcgispro-py3 = original ArcGIS Pro environment created while installing ArcGIS Pro 3.1 (from here called "ArcPro-environment")
- arcgispro-py3-clone3p1 = clone of arcgispro-py3, where I installed Spyder with Anaconda Navigator (from here called "Spyder-environment")
- arcgispro-py3-clone3p1_pch = clone of arcgispro-py3, where I installed PyCharm Professional (from here called "PyCharm-environment")
I hopefully did what you had in mind (I have never worked with PyCharm before):
- Created a fresh clone of the ArcPro-environment (-> PyCharm-environment) and activated it
- Activated the PyCharm-env in Anaconda Navigator
- Installed PyCharm Professional using Anaconda Navigator (I checked the box to update the PATH variable during the installation process)
- Created a new project and set the Python Interpreter Path on the existing Python.exe within the PyCharm-env Environment folder (C:\Users\USER\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone3p1_pch)
--> no error message while importing ArcPy in PyCharm!
Unfortunately, this does not solve my problem, as I could only install the trial version of PyCharm Professional, which is free for 30 days only.
Inspired by this success, I launched Spyder from the Spyder-env in Anaconda Navigator, set the interpreter path accordingly (C:/Users/USER/AppData/Local/ESRI/conda/envs/arcgispro-py3-clone3p1/python.exe) on the Python.exe in the env folder. Additionally, I added the following paths to PYTHONPATH in Spyder:
- C:\Users\USER\AppData\Local\ESRI\conda\envs\arcgispro-py3-clone3p1
- C:\Program Files\ArcGIS\Pro\bin\Python
--> error message while importing ArcPy in Spyder!
Could you explain, what did the trick in PyCharm and how I can do the same for Spyder?
Best,
Johannes

Instead of installing spyder through Anaconda, I'd stick with installing spyder from Pro's package manager because the packages will come from ersi-conda channel/repo first, and not conda-forge. I think you'd get a better dependencies that work with arcpy. You can set the preference and order of these channels, but sometimes the conda will default to what it wants (due to dependencies and what is in your pkg folder), regardless of assignment.
I thought Anaconda came with PyCharm Community so that is a bummer it's Professional, but good to know the issue when spyder is involved. If you are a student or teacher, jetbrains offers free licenses for their IDE's. But, Anaconda also comes with VS Code, so if you are truly stuck in Anaconda maybe try VS Code?
I think the architecture difference between PyCharm and spyder is why spyder has so many issues. PyCharm is built on Java, and is separate from python packages. Spyder is built with/ relies on many of the same python packages that we also use for our code. We may need version 3.1 of a package for our code, but spyder needs 2.8, so one or the other breaks. I could be wrong, but I think it's disastrous trying to coexists for the long term. Maybe some people like having to resolve the environment and spyder every time Pro updates, but I'd rather spend that time working in an IDE that separate, is stable, and only requires pointing to a new interpreter when needed. Life's too short to fight with these things if there are options available.

I tried installing Spyder directly from ArcGIS Pro. This failed for the available Spyder versions 5.4.2 and 5.2.2 because of conflicting dependencies. I attached the protocol, but there are so many conflicts that it is a real mess and I do not expect anybody to unravel this.
I also found the download of PyCharm Community now and installed it. I am gonna make PyCharm to my new IDE to work with in future. Spyder obviously is not able to handle ArcGIS Pro 3.1 on my working environment for the moment.
Thank you, @Anonymous User for these helpful hints. At least you made me understand the advantage of a totally Anaconda-independent IDE, where I can select the interpreter without any interdependencies to other packages.
