ASF subversion and git services commented on SINGA-346:
-------------------------------------------------------

Commit 9090160ed28f2449d73e3bf82fa8cd8c93312eab in incubator-singa's branch refs/heads/master
from Wang Wei
[ https://git-wip-us.apache.org/repos/asf?p=incubator-singa.git;h=9090160 ]

SINGA-346 Update cudnn from V5 to V7

Export numpy path by cmake; no need to export it into a env var now.

replace PYTHON3 with USE_PYTHON3

one bug left due to the unicode and byte string problem from py2 to py3.
which could be resolved by defining SWIG_PYTHON_2_UNICODE in *.i files.
It converts byte string in python2 into unicode and then to c++ std::string.
