@sofiavlachou28 Thanks for your interest in LightGBM! I wrote up a learning-to-rank example tonight to hopefully answer this and other issues you've opened regarding `LGBMRanker` in the Python package (#5297,...

If you use `conda`, you can get an arm64 precompiled binary from `conda-forge`. See https://github.com/microsoft/LightGBM/issues/4369#issuecomment-860083984. ```shell conda install -c conda-forge lightgbm ``` Otherwise, we already have some feature requests for...

They are using `cibuildwheel` to *cross-compile* ARM wheels for Mac on Macs that have Intel chips. https://github.com/scikit-learn/scikit-learn/blob/ec6efc57fac36820919184ffb5fae70a7e871b62/.github/workflows/wheels.yml#L111 https://github.com/scikit-learn/scikit-learn/blob/ec6efc57fac36820919184ffb5fae70a7e871b62/.github/workflows/wheels.yml#L141 Which we have been hesitant to rely on in this project because...

Thanks for those links @StrikerRUS ! I think `scikit-build` is really compelling, since it supports `CMake`. I'll add two more relevant projects here: * https://pybind11.readthedocs.io/en/stable/ * https://cibuildwheel.readthedocs.io/en/stable/

Thanks for those links! But since the environment variable `CI` is such a general-purpose name, and since a CRAN rejection is so expensive (in terms of our time and the...

> Hmm seems like that is expected Yeah there is some interesting sourcing/loading of R code done by `testthat::test_check()` and similar, and I don't think we can rely on environment...

hmmmm ok, and I realize now that even for `lightgbm()` that might not work, since tests that pass `num_threads = {something}` to `lightgbm()` will also not end up calling that...

> Sorry, seems that some checks are failing. I'll fix them first. Ok sounds good. I'd be happy to provide another review once CI is passing. If you encounter errors...
