深度学习Caffe平台安装——Ubuntu安装CPU模式的caffe

按照这篇博客安装正确；

将caffe下拉到/usr/local/lib/python2.7/dist-packages下；

在 make pycaffe 时报错：

src/caffe/layers/image_data_layer.cpp:2:33: Fatal error: opencv2/core/core.hpp: 没有那个文件或目录
compilation terminated.
Makefile:581: recipe for target '.build_release/src/caffe/layers/image_data_layer.o' Failed
make: *** [.build_release/src/caffe/layers/image_data_layer.o] Error 1

解决方法：没有安装opencv依赖

===========

/usr/bin/ld: 找不到 -lopencv_imgcodecs collect2: error: ld returned 1 exit status

解决方法：http://blog.csdn.net/w113691/article/details/77942408

先将Makefile.config文件中

OPENCV_VERSION :=3 注释掉，只修改USE_OPENCV := 1

修改后的结果：

USE_OPENCV := 1

#OPENCV_VERSION := 3

在caffe根目录下，找到Makefile文件，打开文件

查找“Derive include and lib directories”一节，修改“LIBRARIES +=”的最后一行（LIBRARIES +=opencv_imgcodecs），增加opencv_imgcodecs

opencv_core opencv_highgui opencv_imgproc opencv_imgcodecs

（此时应该变为LIBRARIES +=opencv_imgcodecsopencv_core opencv_highgui opencv_imgproc opencv_imgcodecs）

保存，退出。

注意：在做前边的基础工作是将Makefile.config文件中

3 注释掉，只修改USE_OPENCV := 1

再在caffe目录下，sudo make all -j8一下，问题解决

# Uncommentif you're using OpenCV 3 OPENCV_VERSION := 3
