在虚函数后面加一对大括号

$ sudo make pycaffe   出错
CXX/LD -o python/caffe/_caffe.so python/caffe/_caffe.cpp
python/caffe/_caffe.cpp:10:31: fatal error: numpy/arrayobject.h: No such file or directory
compilation terminated.
Makefile:502: recipe for target 'python/caffe/_caffe.so' failed
make: *** [python/caffe/_caffe.so] Error 1

Makefile.config  中   加local

PYTHON_INCLUDE := /usr/include/python2. \

        /usr/local/lib/python2./dist-packages/numpy/core/include

#/usr/lib/python2./dist-packages/numpy/core/include

重新 make pycaffe 就可以了
