mac安装上的python xgboost

Question

我正在尝试在我的Mac上为Python 3.4安装xgboost,但是在"pip3 setup.py install"之后我收到以下错误:

  File "<string>", line 20, in <module>

  File "/private/var/folders/_x/rkkz7tjj42g9n8lqq5r0ry000000gn/T/pip-build-2dc6bwf7/xgboost/setup.py", line 28, in <module>

    execfile(libpath_py, libpath, libpath)

NameError: name 'execfile' is not defined

使用-v选项运行它以获取详细输出时,错误如下所示:

  Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/_x/rkkz7tjj42g9n8lqq5r0ry000000gn/T/pip-build-2dc6bwf7/xgboost

我该如何解决这个问题？

Answer 1

这对我有用.

操作系统:OSX El Capitan

第1 cd xgboost; ./build.sh
步:第2步:cd python-package; python setup.py install

Answer 2

我认为 xgboost 只能通过 pip 作为 Python 2 包使用。有两种可能让它发挥作用。

1. 您使用 Python 2 并通过 pip 安装它。
2. 您可以为 Python 3 手动构建 xgboost。只需从 github 下载源代码并构建它：打开终端。从 git 签出： git clone https://github.com/dmlc/xgboost.git。构建它：cd xgboost；制作; CD 包装纸；python.py setup install --user
