怎样安装?
用pip, 以python 3.7为例子. 最好使用virtual environment.
$ pip install xgboost
$ pip install sklearn
$ pip install libomp
sklearn是scikit learn, 不是必要, 不过里面有些很有用的function, 比如split training and evaluation data.
libomp是OpenMp, 是xgboost package的一个dependency. 不装在Mac上跑不了xgboost.
怎样确认安装成功?
Python 3.7.3 (default, Apr 7 2020, 14:06:47)
[Clang 11.0.3 (clang-1103.0.32.59)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import xgboost
>>>
如果import成功没有error, 就是成功了.
