`conda` installation fails with python 3.13

[tvwenger]

Describe the bug
Neither the conda installation instructions nor the pip installation instructions, both found on this page, are able install a working version of glue.

To Reproduce
First, conda via the glueviz channel:

conda update -n root conda
conda create -n glue -c conda-forge python pip
conda activate glue
conda install -c glueviz glueviz
python --version
# Python 3.13.0
glue --version

Traceback:

Traceback (most recent call last):
  File "/home/twenger/miniconda3/envs/glue/bin/glue", line 6, in <module>
    from glue.main import main
  File "/home/twenger/miniconda3/envs/glue/lib/python3.13/site-packages/glue/__init__.py", line 22, in <module>
    from .config import load_configuration
  File "/home/twenger/miniconda3/envs/glue/lib/python3.13/site-packages/glue/config.py", line 2, in <module>
    import imp
ModuleNotFoundError: No module named 'imp'

Next, conda via the conda-forge channel:

conda deactivate
conda remove --all -n glue
conda create -n glue -c conda-forge python pip
conda activate glue
conda install -c conda-forge glueviz
python --version
# Python 3.13.0
glue --version

Error:

Command 'glue' not found, but can be installed with:
sudo apt install glueviz

Finally, pip:

conda deactivate
conda remove --all -n glue
conda create -n glue -c conda-forge python pip
conda activate glue
conda install -c conda-forge
pip install glueviz[all,qt]
# WARNING: glueviz 1.3.0 does not provide the extra 'all'
# WARNING: glueviz 1.3.0 does not provide the extra 'qt'
python --version
# Python 3.13.0
glue --version
# 1.21.1
glue

Traceback:

Expected behavior
Installation should proceed as advertised.

Details:

• Operating System: Ubuntu/WSL
• Python version (python --version): 3.13
• Glue version (glue --version): Didn't work
• How you installed glue: See above

@tvwenger - thanks for reporting this! The installation instructions for conda were out of date, see the latest version here now:

http://docs.glueviz.org/en/stable/installation/conda.html

Essentially you should use the conda-forge channel instead of the glueviz channel.

For the pip installation, there was an issue with the glueviz meta-package. You should now be able to try again and it should work (but let me know if not!)

[tvwenger]

Thanks for the quick update to the docs @astrofrog ! I can confirm that the pip and conda installations proceed correctly alongside python 3.12.7 (note the other issue about python 3.13).

reopening this since the conda issue still persists at least for Python 3.13. Fresh miniforge 24.11.3 installation with (default) python=3.13.1 fails with :

The following packages are incompatible
└─ glueviz is installable with the potential options
   ├─ glueviz 1.3.0 would require
   │  └─ python >=3.10,<3.11.0a0 , which can be installed;
   ├─ glueviz 1.3.0 would require
   │  └─ python >=3.11,<3.12.0a0 , which can be installed;
   ├─ glueviz 1.3.0 would require
   │  └─ python >=3.12,<3.13.0a0 , which can be installed;
   └─ glueviz 1.3.0 would require
      └─ python >=3.9,<3.10.0a0 , which can be installed.

3.12 (e.g. directly running mamba install glueviz) works, but installs some slightly older versions:

  + glue-core                                      1.21.1  pyhd8ed1ab_1             conda-forge      829kB
  + glue-vispy-viewers                              1.2.2  pyhd8ed1ab_0             conda-forge       91kB
  + glue-qt                                         0.2.0  unix_pyh707e725_0        conda-forge      352kB
  + glueviz                                         1.3.0  py312h81bd7bf_2          conda-forge       20kB

while pip install glueviz[all,qt] gives

glue-core==1.21.1
glue-qt==0.3.1
glue-vispy-viewers==1.2.2
glueviz==1.4.0

glue-qt still not updated (glue-viz/glue-qt#23), but the mamba version in contrast is > 1½ years old.

Seems this comes down to glue-qt not being able to install for 3.13, which in turn is blocked through its dependencies on pyqt and qtconsole in conda (as well as probably the pin on 0.2.0 with other Python versions in conda).
