错误种类：
from /usr/local/lib/python2.7/dist-packages/tensorflow/include/tensorflow/core/framework/op.h:32
fatal error: nsync_time.h: No such file or directory
解决方案：
copyingnsync*.hfromdist-packages/external/nsync/public(or/google/nsync/tree/master/public) to/usr/includealso does the trick without modifying tensorflow files.
