Python Package Manger: How do I install a package that isn't listed?

MichaelMorisette — Fri, 19 Feb 2021 16:31:07 GMT

It appears the available packages to install in Pro is some form of curated list. Is there a way to get this to show everything available in the python package index?

There is a particular package I'm after (python-docx) that isn't listed, and that I'm desiring for a python toolbox tool I'm working on. If I'm unable to install it the clean way, what would be the best workaround of getting it into my Pro Python environment?

You need to create a clone and then you can add packages.

I've had problems with pro's use of conda installing packages (just spins and doesn't do anything) so I add the cloned environment to my list of interpreters in pycharm and add them through there. Sometimes I have to turn off the conda package manager for it to give me the pypi repo. I don't know the specifics behind the scenes, but it allows me to install packages.

... Have they let us name the cloned environments yet?

It isn't in esri's or anacondas default channels, so you could use a conda install (run proenv.bat) and try to install it from the conda-forge channel... failing that, there is always pip install.

If you are uncomfortable with any of these suggestions, then you might want to consider where it is a "need" versus a "nice". You can do a lot of damage if you get things wrong... clone or not.

I know Dan isn't a big fan of clones, but I do them all the time, and I have a few python environments that serve different purposes for me.

When it comes to adding packages to an ArcGIS Pro clone, I typically use

conda install <packageName>

rather than using the installer provided in ArcGIS Pro. In fact I haven't used that approach since yesterday. when I installed spyder in my latest pro 2.7 clone.

This is my go to conda command document:

They meaning the ESRI ArcGIS Pro cloning methodology? The answer is yes. I treat clones as disposable so if something goes south with one I delete and re-clone. In the image below, you'll see that I have a directory in C: called 'EnvClones' where I write them to.

This is what my C:\EnvClones looks like in file explorer:

The MiniConda isn't really a clone but rather a python environment I created with a Miniconda install.

This got me going. Thanks! proenv.bat was the missing link I needed.

Upon doing a conda install ... and resolving the dependencies, I discovered the likely reason my package wasn't listed in default repositories: it resulted in having to downgrade one of the built-in packages! Luckily, so far, this doesn't appear to have messed anything up for me in my clone environment.

Regarding "need" vs "nice," this definitely falls under the nice category. My project is to author a tool that creates a PDF packet containing a formal letter with an attached map, based on user input. My thought was to utilize a company letterhead template we have, versus recreating it from scratch (The python-docx package allows for manipulation of Microsoft Word documents). However, the template is fairly simple so it won't be too cumbersome to just code it using reportlab or something similar.

Cool, thanks Joe. I haven't touched the environments since 2.4 and I remember it was frustrating to have ...clone_1, ...clone_2, ...clone_3 and not being able to tell what they were for.
