Maybe It seems a cause of the problem.

Thanks for reporting this! Hope they restore the repository ASAP.

I don't even understand how this can happen 😭

There aren't any active incidents or reports of degraded service at https://status.gitlab.com/

According to https://gitlab.com/libeigen/eigen/-/issues/2336#note_694339283, the Eigen repo is now back up on GitLab. Not all features of that repo have been restored, but for LightGBM's purposes (just cloning the latest state of the master branch), the repo is up and I believe this issue can be closed.

Just ran the following successfully.

git clone --recursive git@github.com:microsoft/LightGBM.git

Thanks very much for reporting this @lmassaron , and to @TaehyunJo-CP for finding the relevant discussion with the Eigen maintainers.

@jameslamb Just one minor note

... but for LightGBM's purposes (just cloning the latest state of the master branch) ...

We are not cloning the latest state of the Eigen repo, but a particular one specified via a commit hash:
https://github.com/microsoft/LightGBM/tree/master/external_libs
Right now it is 8ba1b0f.

Ah ok, maybe I misunderstood how submodules work. I didn't see any specific commits referenced in https://github.com/microsoft/LightGBM/blob/a77260f03eb735923125024b0f36df9f63a6e0f3/.gitmodules
