Conda packages for SageMath with Python 3.8 #59

Closed nthiery closed 3 years ago

nthiery commented 3 years ago

The latest jupyter/xxx-notebook images (e.g. used by binder) are based on Python 3.8. This seems to be incompatible with the current conda packages:

docker run -ti --user root jupyter/minimal-notebook bash

(base) root@fae0b6c00255:~# conda install mamba -c conda-forge

(base) root@fae0b6c00255:~# mamba install sage
...
Encountered problems while solving.
Problem: nothing provides path.py >=7.1,<8 needed by sage-8.1-py27_1

(base) root@fae0b6c00255:~# mamba install sage=9.1
...
Encountered problems while solving.
Problem: package sage-9.1-py37hc8dfbb8_0 requires python >=3.7,<3.8.0a0, but none of the providers can be installed

We'll have to wait till sage 9.2 to support python 3.8

nthiery commented 3 years ago

Oh, I see. I assumed that sage 9.0 already supported Python 3.8 because this is the case with the Debian package on Ubuntu 20.04:

> sage
┌────────────────────────────────────────────────────────────────────┐
│ SageMath version 9.0, Release Date: 2020-01-01                     │
│ Using Python 3.8.2. Type "help()" for help.                        │
└────────────────────────────────────────────────────────────────────┘

I guess Debian is doing some patching to achieve this.

Thanks for the feedback though!

The good news is that Sage 9.2 will also support Python 3.9, thanks to Sage Trac ticket 30184 merged in Sage 9.2.rc0. : )

Also discussed on sage-devel: https://groups.google.com/d/topic/sage-devel/d2a_0g1OlvE/discussion

Hi - I understand 9.2 was released yesterday. Any idea on when it will become available on conda-forge? Also, I was wondering, seeing that conda-forge has no Windows version for this package, if there was a technical reason for it?

You can follow the development at https://github.com/conda-forge/sagelib-feedstock/pull/105 As for windows, sage provides windows support only through cygwin (a linux emulation software) which we don't support at conda.

Thank you for the info !
