OS X import error for cudnn #1772
Description
I'm getting this when I try to import torch:
Python 3.5.2 |Continuum Analytics, Inc.| (default, Jul 2 2016, 17:52:12)
[GCC 4.2.1 Compatible Apple LLVM 4.2 (clang-425.0.28)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import torch
Traceback (most recent call last):

I did not see any errors during installation. My installation command was:
export CMAKE_PREFIX_PATH=/Volumes/home500/anaconda/
export MACOSX_DEVELOPMENT_TARGET=10.9
MACOSX_DEPLOYMENT_TARGET=10.9 CC=clang CXX=clang++ pip install git+git://github.com/pytorch/pytorch
And the version of clang seems to be right:
clang -v
Apple LLVM version 7.3.0 (clang-703.0.31)
Target: x86_64-apple-darwin16.6.0
Thread model: posix
