python xgboost on mac install

问题

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":

  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:

  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?

回答1:

This worked for me.

OS: OSX El Capitan

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

回答2:

I think that xgboost is just available as Python 2 package over pip. There are two possibilities to get it working.

You use Python 2 and install it with pip.
You can manually build xgboost for Python 3. Just download the source from github and build it: Open Terminal. check out from git: git clone https://github.com/dmlc/xgboost.git. build it: cd xgboost; make; cd wrapper; python.py setup install --user

回答3:

perhaps you should use

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

instead of

cd xgboost; ./build.sh

as per the "Build On OSX" Section of build document

also perhaps this is a duplicate

I've got many errors trying to install XGBoost on a Mac OS X Mojave 10.14 following the instructions building from sources. The worst one was when invoking CMake didn't work and the infamous clang: error unsupported option '-fopenmp'. A real C++ build / compilation nightmare...

Since I was not able to compile the native C++ library finally I succeeded using this workaround procedure:

Using brew to get the compiled library libxgboost.dylib:

brew install xgboost

Strangely enough, brew didn't install the whole thing!!??
Install the Python library:

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

cd xgboost
Install the compiled library libxgboost.dylib and link to it:

mkdir lib

cd lib

ln -s /usr/local/Cellar/xgboost/0.90/lib/libxgboost.dylib ./libxgboost.dylib
Install the Python package

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.

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
