Thanks for contributing to LightGBM!

The CI failures are not something you need to worry about. We are currently working through some instability in the project's CI (see #5510) and will come back to merge this after those are resolved. Sorry for the inconvenience.

@Madnex ok, the project's CI issues have been fixed (#5510).

Sorry for the inconvenience, but can you please merge the latest changes from master into this branch? If CI succeeds after that, we'll merge this.

Thanks again for contributing to LightGBM!

[Madnex]

Thanks! I merged it 👍

[jameslamb]

Thanks again for this!

@Madnex in the future, I strongly recommend that you create a branch on your fork, instead of committing directly to master and then opening a pull request from there.

Now that I've merged this, your master will have commits on it that aren't on LightGBM's master here, and vice versa.

If you want to keep contributing (and I hope you do!), the easiest way to fix that is probably just to:

• delete your fork of LightGBM
• re-fork LightGBM
• submit all future pull requests from a branch that you cut off of master, like this

git clone --recursive https://github.com/Madnex/LightGBM.git
cd LightGBM
git checkout -b some-feature

👋 cheers and have a good weekend!

[Madnex]

Thanks for the tipp @jameslamb ! Will do and prepare the next PR :)
