xgboost installation issue with anaconda

I am using Anaconda. I first switched to Python2 (Version 2.7.11).

python -V
Python 2.7.11 :: Continuum Analytics, Inc.

I used the following command to install xgboost in anaconda.

conda install -c https://conda.anaconda.org/akode xgboost

I then checked that xgboost is installed.

conda list
xgboost                   0.3                      py27_0    akode

I run python in terminal, import xgboost and got the following errors.

import xgboost as xgb

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "//anaconda/envs/wen2/lib/python2.7/site-packages/xgboost.py", line 82, in <module>
    xglib = load_xglib()

    self._handle = _dlopen(self._name, mode)
OSError: dlopen(//anaconda/envs/wen2/lib/python2.7/site-packages/libxgboostwrapper.so, 6): Library not loaded: @rpath/./libgomp.1.dylib
  Referenced from: //anaconda/envs/wen2/lib/python2.7/site-packages/libxgboostwrapper.so
  Reason: image not found

I have no idea what to do next.

The package image you download is corrupt. What you should do :

First remove your xgboost package with (in the terminal) :

conda remove xgboost

Then reinstall with an other package at https://anaconda.org/aterrel/xgboost So just write :

conda install py-xgboost

Then you can check the installation in the python console :

import xgboost

It should be ok.
