I am trying to install xgboost on my Mac for Python 3.4 but I'm getting the following error after pip3 setup.py install
:我正在尝试在 Mac 上为 Python 3.4 安装 xgboost,但在pip3 setup.py install
后pip3 setup.py install
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
When running it with the -v option to get the verbose output the error looks like this: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

How can I solve this issue?我该如何解决这个问题?
This worked for me.这对我有用。
OS: OSX El Capitan操作系统:OSX El Capitan
Step-1: cd xgboost; ./build.sh
第一步: cd xgboost; ./build.sh
cd xgboost; ./build.sh
Step-2: cd python-package; python setup.py install
第二步: cd python-package; python setup.py install
cd python-package; python setup.py install
I think that xgboost is just available as Python 2 package over pip.我认为 xgboost 仅作为 Python 2 包通过 pip 提供。 There are two possibilities to get it working.有两种可能性可以让它工作。
I've got many errors trying to install XGBoost on a Mac OS X Mojave 10.14 following the instructions building from sources .我尝试按照从源代码构建的说明在 Mac OS X Mojave 10.14 上安装 XGBoost 时遇到很多错误。 The worst one was when invoking CMake didn't work and the infamous clang: error unsupported option '-fopenmp'.最糟糕的是当调用 CMake 不起作用和臭名昭著的 clang: error unsupported option '-fopenmp' 。 A real C++ build / compilation nightmare...一个真正的 C++ 构建/编译噩梦......
Since I was not able to compile the native C++ library finally I succeeded using this workaround procedure:由于我最终无法编译本机 C++ 库,因此我成功地使用了以下解决方法:
Using brew to get the compiled library libxgboost.dylib:使用brew获取编译库libxgboost.dylib:
brew install xgboost
Strangely enough, brew didn't install the whole thing!!??奇怪的是,brew 没有安装整个东西!??
Install the Python library:安装 Python 库:
git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
Install the compiled library libxgboost.dylib and link to it:安装编译库 libxgboost.dylib 并链接到它:
mkdir lib
cd lib
ln -s /usr/local/Cellar/xgboost/0.90/lib/libxgboost.dylib ./libxgboost.dylib
Install the Python package安装 Python 包
cd ../python-package
sudo python3 setup.py install
Again, strangely enough, setup.py installs partially the egg package, so I have to copy manually the xgboost package directory to site-packages.同样,奇怪的是,setup.py 部分安装了 egg 包,所以我必须手动将 xgboost 包目录复制到 site-packages。
cp -r xgboost /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/
By the way, I've also to upgrade dask: sudo pip3 install --upgrade dask
顺便说一句,我还升级了 dask: sudo pip3 install --upgrade dask
