Thanks for using LightGBM. It's very difficult to help you based only on an error message. Could you give us some more information please? * what version of LightGBM? *...

**without any code changes** most recent `cucim` builds did succeed ([build link](https://github.com/rapidsai/cucim/actions/runs/12249757626)). However, I still put up #801 temporarily allowing clobbering, in case other steps in the `xorg-*` migration result...

Thanks very much for the quick and thorough response, and for maintaining this project! This greatly improved my understanding of how/when `rchk` is run by CRAN. > _Rchk has initially...

As for the root cause, for anyone who wants to investigate this... I suspect the problem is that the weight column is left behind in column names because we don't...

Thanks for using LightGBM, and for taking the time to put together an excellent reproducible example! ## Short Answer During tree-building, LightGBM looks at multiple "splits", `(feature, threshold)` pairs. For...

@bdice I think we can close this, given that we instead went the route of making whether or not the `*-build` shared workflows try to upload artifacts to GitHub Actions...
