             Summary: Import pyarrow fails if scikit-learn is installed from 
conda
                 Key: ARROW-3048
                 URL: https://issues.apache.org/jira/browse/ARROW-3048
             Project: Apache Arrow
          Issue Type: Bug
          Components: Python
    Affects Versions: 0.10.0
         Environment: Ubuntu 16.04
            Reporter: Jarno Seppanen


Hi, installing both pyarrow 0.10.0 and scikit-learn 0.19.2 causes pyarrow 
import to break.

Steps to reproduce
 # cat >environment.yml <<EOF

{code:java}
name: asdf
channels:
- defaults
- conda-forge
dependencies:
- python=3.6
- pyarrow=0.10.0
- scikit-learn=0.19.2{code}
EOF
 # conda env create
 # source activate asdf
 # python -c 'import pyarrow'

{code:java}
