我在编译pycaffe的操作的时候，看见了下面的错误，编译命令为：

make pycaffe


错误的输出为： 

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:507: recipe for target 'python/caffe/_caffe.so' failed
make: *** [python/caffe/_caffe.so] Error 1


通过查阅资料，我的解决办法是： 

sudo gedit Makefile.config


#找到这条语句，然后要加一个local： 
PYTHON_INCLUDE := /usr/include/python2.7 \
        /usr/local/lib/python2.7/dist-packages/numpy/core/include


然后运行命令： 

make pycaffe -j8

输出为： 

CXX/LD -o python/caffe/_caffe.so python/caffe/_caffe.cpp


然后加入环境变量,我的caffe路径为export PYTHONPATH=/home/whsyxt/Downloads/caffe/python:$PYTHONPATH：

sudo gedit ~/.bashrc  #打开  
export PYTHONPATH=/home/usrname/caffe/python:$PYTHONPATH   #配置文件最后写入该路径，
source ~/.bashrc   #生效

然后运行python，测试一下： 

whsyxt@whsyxt:~/Downloads/caffe/python$ python
Python 2.7.12 (default, Nov 19 2016, 06:48:10) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import caffe
>>> exit()


成功了。
