python xgboost on mac install

Question

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?

Answer 1

This worked for me.

OS: OSX El Capitan

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

Answer 2

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

1. You use Python 2 and install it with pip.
2. 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
