xgboost交叉验证以及n_jobs报错
今天用xgboost跑了一下分类发生如下报错：
A worker process managed by the executor was unexpectedly terminated.
This could be caused by a segmentation fault while calling the function or by an excessive memory usage causing the Operating System to kill the worker.
这是显存不足造成的。
解决方案
制定富裕空间的显卡
import os
os.environ["CUDA_VISIBLE_DEVICES"] = "0"
