cif2cell breaking conda-forge recipe

[wd15]

cif2cell is not updated on conda-forge (it's only available for Python 2.7). It is up to date on pip at version 2.0.0a3. However, it's also not possible to pip install to build a conda-forge recipe.

Possible options to fix this are:

• Don't make cif2cell a strict dependency (make it optional) until it's updated on conda-forge. Good option if it's only a niche usage in Jarvis. Raise an error in jarvis where it's used and say that you need to install with pip install. Try to quarantine it's usage a bit so the import is only in the function where it's used.
• Contact the authors and ask them to update conda-forge recipe
• Remove its usage and look for alternatives.

When I remove cif2cell I get this error. Obviously, Jarvis now requires cif2cell.

With cif2cell I get this error. cif2cell is very old in conda-forge.

Here is one of the issues:

@wd15 I have removed cif2cell hard-dependency now.

[wd15]

Great. That merges now so new release should be available soon.

I installed with conda install -c jarvis-tools and I'm getting version 2020.11.27 for some reason?!?

If I do conda search -f jarvis-tools, I get

Could it be that the version isn't ordering properly. Maybe can you try using a version number of 2021.04.30 for example so always have two digits for the day and year. For, example, if I do the same for pandas then it's nicely ordered. I'll check the settings as well to see if we can change something to get the version ordering correct.

Edit: Sorry, I'm going crazy, it is correctly ordered. Ignore that.

Edit again: I need to figure out why it's not giving me the latest version by default.

Yea, in pypi, it seems to work fine: https://pypi.org/project/jarvis-tools/#history

[wd15]

I've seen this with other packages as well when there's an issue with dependencies and precedence. For example, installing sfepy used to change the environment from Python 3 to 2.

A few stackoverflow links 1, 2.

I'm not sure what to do. I suggest changing the install instructions to say do

$ conda install -c conda-forge jarvis-tools=$(conda search -f jarvis-tools | tail -1 | awk '{print $2}')

but that's gruesome. Maybe just say use conda-forge search -f jarvis-tools to find latest version and then specify the latest version.

Conda is such a pain with the way it resolves packages.

[wd15]

What happens when you install jarvis-tools. do you get the latest version or same as me?

[knc6]

So, I created a new conda environment and ran conda install -c conda-forge jarvis-tools . It does install 2021.4.18 not 2021.4.28 which is weird.

[knc6]

Actually I dont see the 2021.4.28 version on the conda search:
conda search -f jarvis-tools -c conda-forge

[wd15]

Probably hasn't propogated to conda-forge yet. Let's try again next week
