Provide Anaconda package

[impredicative]

Noting that pandas is available as a conda package in the conda-forge and anaconda channels, I request that py-polars also be available similarly. If provided, it would have to consistently be released at about the same time as the PyPI package. This is a low priority request as I can currently install and use the PyPI package.

To my knowledge compiling for anaconda isn't trivial. It assumes pure python code, or a not-Rust compiler.

I shall tag it help-wanted. Maybe someone with more knowledge on anaconda/ cross-compiling could pick that up.

I can try creating a conda package in 1-2 weeks if others don't succeed.

[ritchie46]

@alippai That would be great!

@alippai @ritchie46 Any update on creating a conda package?

I started a PR on conda-forge for polars. But am getting errors for the following experimental feature (SIMD). How do I disable SIMD while building polars for conda?

Link to code: SIMD

conda-forge polars branch: https://github.com/sugatoray/staged-recipes/tree/polars
PR: conda-forge/staged-recipes#16717
Latest job run failure (at build stage): https://dev.azure.com/conda-forge/feedstock-builds/_build/results?buildId=401212&view=logs&j=6f142865-96c3-535c-b7ea-873d86b887bd&t=22b0682d-ab9e-55d7-9c79-49f3c3ba4823

@sugatoray the issue is that simd is a nightly-only experimental API and therefore Polars needs rust-nightly to compile.
I created a PR here (conda-forge/staged-recipes#18906) and got most of my inspiration from ORJSON's feedstock (https://github.com/conda-forge/orjson-feedstock) to download and install rust-nightly from linux and windows.

@Maxyme hopefully yours works, mine was working but it takes >6 hours to run and times out conda's build limit

[Maxyme]

@timkpaine Thanks for the information, I was able to have a succesful macos build yesterday, and it looks like linux works too, just having some issues still with the windows build, either I can fix it, or will disable it for now.

[timkpaine]

@Maxyme if you skip windows for now and add me on the feedstock I can look at windows. I would also add @ritchie46 and @sugatoray to the feedstock list (you can add folks after the feedstock is made with a simple command that skips CI as well)

[Maxyme]

@timkpaine I updated the pr to add suggested maintainers and skipping windows builds for now. Thanks for looking into this, I think it's quite close to building successfully, I linked the issue as a comment in the meta.yaml to help for the subsequent builds.
I'm excited to see this project on conda as it will open it up to more users.

[timkpaine]

Awesome this is good, im glad this will finally get across the line after 5 attempts! It will be good for other rust-based python projects down the line as well as this is likely the most popular/visible one onboarding to conda forge

[sugatoray]

@Maxyme Thank you, for putting time into this and making it work. 🚀

Update: polars is now an anaconda package on channel conda-forge: https://anaconda.org/conda-forge/polars/files.
