Detailed steps to reproduce

conda install pytorch-nightly -c pytorch
DETECTRON=/path/to/clone/detectron
git clone https://github.com/facebookresearch/detectron $DETECTRON
pip install -r $DETECTRON/requirements.txt
cd $DETECTRON && make
python $DETECTRON/detectron/tests/test_spatial_narrow_as_op.py

System information

• Operating system: Ubuntu 16.04
• Compiler version: Cmake 3.12.0
• CUDA version: 9.2
• cuDNN version: 9.0
• NVIDIA driver version: 396.37
• GPU model: Nvidia K80
• PYTHONPATH: empty
• python --version output: Python 2.7.15 :: Anaconda, Inc.
• Anything else that seems relevant:
  Caffe2 is working fine on it's own, i'd rather stay with my versions of cuda and cudnn as I am using other deep learning frameworks that work fine with those versions
  I tried compiling the sources without using Anaconda, caffe2 was not working with the following error:
  CRITICAL:root:Cannot load caffe2.python. Error: No module named 'caffe2.python.caffe2_pybind11_state'
  I tried adding /path/to/caffe2/build to PYTHONPATH, but there is no build folder in .../anaconda3/envs/caffenv/lib/python2.7/site-packages/caffe2, only contrib proto and python folders

Thank you for your help !
