The `astropy<5,>=3.2` dependency makes poliastro not installable on Python 3.10.2 since astropy-4.3.1 does not install on that version of python #1496

danielk333 · 2022-04-06T14:00:21Z

🐞 Problem

When installing poliastro trough pip on python 3.10.2 it uses astropy-4.3.1 which fails installation with the error message ImportError: cannot import name 'soft_unicode' from 'markupsafe'.

💡 Possible solutions

Upgrading the dependency to astropy>=5 and consequence revising the usage of astropy accordingly would probably make poliastro also support python >= 3.10.

Hello @danielk333 , thanks for opening this issue!

The error you mention seems to be pallets/markupsafe#284. However, I don't see markupsafe in your pip freeze, as I don't see astropy or poliastro either. I suspect your pip freeze is not displaying the dependencies you wanted to share.

Can you paste a complete traceback of the error you are witnessing?

astrojuanlu · 2022-04-07T20:16:47Z

I see - so, the problem is that "pip install 'astropy<5'" fails on Python 3.10? Probably this should be reported upstream.

At some point soon we'll release a bugfix for compatibility with Astropy 5.

danielk333 · 2022-04-08T07:02:14Z

I hesitated to open an issue upstream on it as astropy states

Please check that the development version still produces the same bug.
You can install development version with
pip install git+https://github.com/astropy/astropy
command

which it does not since they fixed that problem in astropy>=5.

astrojuanlu · 2022-04-08T14:36:42Z

Good point. In that case, I'll keep this open so that we can make poliastro work with the latest version of Astropy

yakkonaut · 2022-04-13T18:59:00Z

Just leaving notes for folks who find themselves here after a google search:
The issue with installing the older version of astropy actually goes back to the library markupsafe which deprecated "soft_unicode" in favor of "soft_str"... then broke it in a minor version.

Ref: pallets/markupsafe#284

As @danielk333 noted, astropy 5.x fixed this.

I'm trying to integrate someone else's code in to an existing project where they used poliastro... I wouldn't put this issue specifically on the poliastro or astropy teams- it's weird that markupsafe did this breaking change on a minor version. That said, now I can't figure out if it will be faster to change the math to skyfield or to try and help fix poliastro. I'm brand new to this codebase- will start reading around. Appreciate you all!

yakkonaut · 2022-04-13T19:00:16Z

Sorry for double post- derpped. I saw the markupsafe ref above but didn't realize it linked to the same issue. Point still stands though, it's an awkward fix they could have avoided by not forcing deprecation until next major version -,-

astrojuanlu · 2022-04-14T16:57:49Z

Thanks for the extra info @yakkonaut - all help is welcome to make poliastro work with Astropy 5 (#1493). I'm on PTO and ramping up a new job but I hope I'll have the resources to cut a bugfix release soon.

Hopefully #1501 fixes this, please have a look.
