Pinned Conflicts while installing Glueviz

Question

I want to install the Glueviz software using ananconda python distribution, but unable to do so. Here are the steps I did in the anaconda shell

1. conda update -n root conda
2. conda create -n glueviz-env python
3. conda activate glueviz-env
4. conda install -c glueviz glueviz

After this it showed me an error.

Channels:
 - glueviz
 - defaults
Platform: linux-64
Collecting package metadata (repodata.json): done
Solving environment: \ warning  libmamba Added empty dependency for problem type SOLVER_RULE_UPDATE
failed

Pins seem to be involved in the conflict. Currently pinned specs:
- python 3.12.* (labeled as 'pin-1')

I tried this following modification as mentioned here- CONDA_CHANNEL_PRIORITY=flexible conda install -c glueviz glueviz

but nothing worked. This is my output

I will be grateful if anyone helps me with this issue. Thanks

Answer 1

The glueviz-feedstock has not yet successfully rebuilt for Python 3.12 (a.k.a., migrated for Python 3.12). Generally, one should prefer specifying all requirements at creation time. Also, the glueviz channel has not updated the glueviz package for a couple years, so I would not recommend using that. Try something like

conda create -n glueviz-env -c conda-forge glueviz python=3.11

Or use a lower Python version.

Note on solve speeds

In test solving, I see a fresh glueviz environment needs to install 300+ packages, which means a formidable solve. I wouldn't try that with anything but Mamba or the latest Conda (which now uses libmamba as its solver). But one can slightly speed up the solve by prespecifying some things, e.g.,

mamba create -n glueviz-env -c conda-forge \
  python=3.11 glueviz==1.2.0 glue-core==1.17.1

That still takes ~40 seconds to solve.
