@shiyu1994 now that recent CI issues have been addressed, I just pushed 29d5735 updating this with |

The self-hosted CUDA machine has a driver issue again. Reboot the machine and reopen this PR. |

@shiyu1994 ping me when this PR is ready |

@guolinke Some segment faults are failing. Will fix them soon. BTW, this PR refactors the cuda objective classes into a more elegant format. So it does not only add an objective and there will be more code changes. |

@shiyu1994 I'm seeing those same segfaults on the I've been trying different things on #5588 and so far haven't been able to fix it 😭 . |

@shiyu1994 I just updated this to latest |

Close and reopen to trigger ci test. |

Add Poisson regression objective for cuda_exp. We noticed that for Poisson regression, the results of
test_regressionintest_engine.pyis slightly worse than CPU version. We conjecture there's still minor difference between details ofcuda_expandcpu. We will record it in an issue for now and fix the gap later on.
