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

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

Answer 2

我认为xgboost只是作为Python 2包而不是pip。有两种可能性让它发挥作用。

您使用Python 2并使用pip安装它。
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中查看：git clone https://github.com/dmlc/xgboost.git。建立它：cd xgboost;使; cd包装器; python.py setup install --user

Answer 3

也许你应该使用

cd xgboost; cp make/minimum.mk ./config.mk; make -j4

而不是

cd xgboost; ./build.sh

根据＆＃34; Build On OSX＆＃34;构建文档部分

也许这是一个duplicate

Answer 4

按照指示building from sources，尝试在Mac OS X Mojave 10.14上安装XGBoost时遇到很多错误。最糟糕的情况是调用CMake无法正常工作，并且臭名昭著的clang：错误不受支持的选项'-fopenmp'。真正的C ++构建/编译噩梦...

由于我最终无法编译本机C ++库，因此我成功使用了此替代方法：

使用brew获取编译的库libxgboost.dylib：

brew install xgboost

奇怪的是，brew并没有安装整个东西！！？
安装Python库：

git clone --recursive https://github.com/dmlc/xgboost

cd xgboost
安装编译的库libxgboost.dylib并链接到它：

mkdir lib

cd lib

ln -s /usr/local/Cellar/xgboost/0.90/lib/libxgboost.dylib ./libxgboost.dylib
安装Python软件包

cd ../python-package

sudo python3 setup.py install

同样，奇怪的是，setup.py会部分安装egg软件包，因此我必须手动将xgboost软件包目录复制到site-packages。

cp -r xgboost /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/

顺便说一句，我也要升级dask：sudo pip3 install --upgrade dask

mac安装上的python xgboost
