Installing Anaconda for Python 3.6 without wrecking Python 2.7

JustinBridwell2 — Mon, 13 Aug 2018 18:33:00 GMT

Hey All- I have both Python 2.7 with ArcGIS 10.5 Desktop and Python 3.6 with ArcGIS Pro. A few weeks back, I tried to install Anaconda (w/ Conda, Spyder, Jupyter, etc..) and it somehow overwrote my system settings for Python 2.7 (as well as pip). I noticed that I could no longer use pip or import stuff in 2.7. I uninstall Anaconda and the updated version of pip (it somehow updated the pip version) and everything in 2.7 worked again. Any suggestions on reinstalling Anaconda with wrecking my Python 2.7 development environment again?

Can you elaborate more on "I noticed that I could no longer use pip or import stuff in 2.7." After installing Anaconda, how were you trying to execute the 2.7 pip?

Well, for example, I might try to run a command like "?pip install arcpy" and it would return an error saying pip is not a command. Since, posting this initial question, I went ahead with installing Anaconda. I have the 'arcgis' package installed through Conda on ArcGIS Pro, but when I try to import it from Jupyter or the Spyder IDE, I get the error: "ModuleNotFoundError: No module named 'arcgis'". I run $conda list and it shows that arcgis package is installed under my arcgispro-py3 folder. This is my current problem and what I was trying to avoid. Any suggestions?

It sounds like you now have 3 Python installations on your machine: Python 2.7 from ArcGIS Desktop, Python 3.6 from ArcGIS Pro, and Python 3.6 from Anaconda. Correct?

What does your PATH environment variable look like, at least the portions tied to Python installations? How are you launching Jupyter?

Regarding using Spyder, I think there have been some issues lately with it and Pro's bundled Python. It might be worth a quick search on GeoNet on that topic for other threads.

What I didn't realize is that the version running in my arcgispro-py3 environment is 3.5.4. I installed Anaconda 3.6. Now when I try to run >import arcgis I get the error: ModuleNotFoundError. The Anaconda/Continuum documentation says to run >conda install python=3.5 , but in what path? If I just go to my user directory and run >python --version, in the Anaconda command prompt, it says python 3.6.5.

If your arcgispro-py3 environment is 3.5.4, you are running an older version of Pro. Pro 2.1 introduced Python 3.6.x. Is there a reason you are running an older version? If you can upgrade, I would start there.

Instead of focusing on all of these symptoms/issues, I think it would be good to step back and focus on what you are trying to achieve. If you install Pro 2.2.x, the bundled Python distribution is fairly comprehensive and includes ArcPy, ArcGIS API for Python, Jupyter, and many SciPy packages. Is there a reason you need to install Anaconda?

I actually have ArcGIS Pro 2.0. This is just what was sent to me (my company IT department - I'm a new employee-trying to set up my dev environment) so I just went with it. My ultimate goal here is to access the arcgis package (specifically >import GIS from arcgis.gis) so that I can utilize the ArcGIS API for Python to make calls to a REST service map server. It was just recommended (by the ArcGIS API documentation and my coworkers) that I use Anaconda with Spyder/Jupyter notebook. At this point I don't think I have the option for Pro 2.2.x.

Besides new functionality and numerous bug fixes, the newer versions of ArcGIS Pro just work with ArcGIS API for Python. ArcGIS Pro 2.0.x is in Mature Support and will be retired by Esri on January 01, 2019. Once a product is retired, you won't get any support from Esri, so you will have to upgrade Pro sooner than later, might as well be now.

Seeing this question, https://community.esri.com/thread/219658-using-the-arcgis-api-for-python-with-a-rest-service , I assume you got it working, more or less. I will go ahead and mark this assumed answer.

Yes. I was able to get Jupyter Notebook working and import the arcgis api module. I pretty much scrapped the full Anaconda install yesterday, but just did a reinstall. The verdict is still out, but I'd like to get Spyder working as my primary 3.6 IDE and use Jupyter for testing.

This was a difficult question to answer but I was finally able to install Anaconda and having it working with my version of ArcGIS Pro (2.2) and Python (3.6). Most importantly, I can now use both the Jupyter Notebook AND the Spyder IDE. The Jupyter Notebook came bundled with the new version of ArcGIS Pro that I installed, so that issue was taken care of. However, I did a reinstall of Anaconda 3.6 and found that I did not have important packages like arcpy and arcgis (the ArcGIS API for Python essentially). I finally found a a work through that did the trick. Here's a link. Essentially, you have to copy the folder arcgispro-py3 from C:\Program Files\ArcGIS\Pro\bin\Python\envs and paste to C:\Anaconda2\envs. The, rename the copied folder arcgispro-py3 in C:\Anaconda2\envs to arcpro. You have to do 2 main things from there; launch your Anaconda Navigator and check in the Environments tab to make sure that there is an arcpro environment. Then, when you launch Spyder, it will ask you if you want Spyder to access the new arcpro environment. Just click yes. The test it out by typing `:import arcpy`. It should run the code without throwing an error. Finito!

Justin,

Glad you found a workable option. You should be able to install Anaconda Navigator and Spyder from an ArcGIS environment, but going the other way is also useful. We're working on further improvements to make this process smoother in the future, purely copying the files can have problems if there are hardcoded paths in the files, but if it works, I won't complain!

Cheers,

Shaun

Hi Shaun,

Any updates on a smoother process? Trying to run Desktop and Pro as well as Anaconda Python 2.7 32-bit for use in Spyder IDE. This is throwing errors in Pro for basic tools. I'd rather not mess around copying and pasting files if I don't have to. Any official suggestion?

Thank you.

We don't have a public release of what we're working on for this yet, but it's definitely on our release roadmap. In Pro 2.3, you can link Pro to an external environment, which may be helpful for your needs. If you're just using a 32-bit Anaconda installation, Pro should be entirely separate since it's all 64-bit as is the conda environments it creates. If you're seeing cross-talk in Spyder between Pro and your Anaconda installation, could you share some details of what the error your seeing is and I can try to troubleshoot them?

Cheers, Shaun

Hey Shauna,

Great to hear. I reinstalled again and now have an environment for 2.7 in Anaconda. Now I want to have a second environment for Pro with Python 3.6. Can I just copy my env file from Pro and pluck it into my Anaconda env folder as I did for 2.7 or do I need to do something else? Any suggestions?
