nothing provides requested pandas 1.5.2

[YarShev]

Hi guys,

We (Modin) use conda-incubator/setup-miniconda@v2 to install packages for the development environment in our GH Actions workflows for testing (e.g., here). Pandas recently released 1.5.2 version and it is already available in conda-forge (link). However, using our environment-dev.yml to install dependencies in GH Actions workflows we see the error.

Encountered problems while solving:
    - nothing provides requested pandas 1.5.2

See the related issue in our repo - modin-project/modin#5256.

We would be really appreciate if you could tell us what is going on wrong. It really stops us to make a release and probably others who is experiencing the issue.

Thanks in advance.

Hi @YarShev, even when packages show up on forge https://anaconda.org/conda-forge/pandas, it might take a while for the metadata that conda forge relies on to get updated. This should be a matter of hours hopefully and it is not related with setup-miniconda.

I just tried locally installing pandas and I get the same error.

Hi @goanpeca, it is very strange. I was able to install pandas 1.5.2 locally even yesterday.

unless specifically overridden per-feedstock, conda-forge now only generates .conda files. if you've configured use-only-tar-bz2: true for caching in the workflow, it's not going to find any new packages.

@bollwyvl, use-only-tar-bz2: false seems to be working. Thanks.

What do you mean by "overridden per-feedstock"?

What do you mean by "overridden per-feedstock"?

It means that unless othwerwise specified on each conda forge recipe feedstock, only .conda artifacts will be generated.

Last time I checked conda was always redownloading everything if .conda files were used, maybe it has been fixed in recent versions, otherwise caching will no longer work with this action (until that is fixed... )

@bollwyvl, @goanpeca, got it, thank you a lot. Closing the issue.

This section in the docs specifies how to configure a feedstock to output .tar.bz2 artifacts: https://conda-forge.org/docs/maintainer/conda_forge_yml.html#conda-build
