Default rdkit from conda uses outdated version about conda-rdkit

[pbjarterot]

for me it worked with :

conda install -c conda-forge rdkit=2021.09.1

conda install -c rdkit rdkit=2020.03.2 works for me.

As @gfrogat showed in rdkit/rdkit#3062, it seems that the rdkit channel is not up to date but that conda-forge is. Consequently, conda create -c conda-forge -n my-rdkit-env rdkit should give latest version.

And I confirm that rdkit version depends on python's version installed via rdkit channel. On my tests, I had:

• conda create -c rdkit -n test rdkit ==> rdkit/linux-64::rdkit-2018.03.2.0-py36h6bb024c_1
• conda create -c rdkit -n test python=3.6 rdkit ==> rdkit/linux-64::rdkit-2018.03.2.0-py36h6bb024c_1
• conda create -c rdkit -n test python=3.7 rdkit ==> rdkit/linux-64::rdkit-2020.03.3.0-py37hc20afe1_1
• conda create -c rdkit -n test python=3.8 rdkit ==> UnsatisfiableError
• all my test with conda-forge used conda-forge/linux-64::rdkit-2020.03.6-*

More on the UnsatisfiableError:

conda create -c rdkit -n test2 python=3.8 rdkit

@antoson oh, actually, the docs were just updated today to use the conda-forge channel: https://www.rdkit.org/docs/Install.html. See also the latest email from Greg: https://www.mail-archive.com/[email protected]/msg10517.html

It would be nice if the latest released version is installed automatically.

I opened a similar issue in the main RDKit repo rdkit/rdkit#3062

It seems the RDKit version also sometimes depends on the Python version that is used for the environment.

[antoson]

Installing from conda-forge channel gets the latest version (2020.09.5) conda install -c conda-forge rdkit .
I was really surprised that conda create -c rdkit -n my-rdkit-env rdkit from official docs doesn't install latest version 🤔.
