[acimmarusti]

Environment info

Operating System: Debian GNU/Linux 8.x (jessie)

Compiler: g++ 4.9.2

Package used (python/R/jvm/C++): Python

xgboost version used: 0.6a2

If you are using python package, please provide

1. The python version and distribution Python 2.7.9

2. The command to install xgboost if you are not installing from source pip install xgboost --pre

3. scipy 0.18, numpy 1.11.2, scikit-learn 0.18

4. import xgboost as xgb

5. Throws attribute error for scipy

Here is what I get exactly when trying to import xgboost:
