所以我用python 2.7安装了anaconda，并安装了Caffe库的所有需求。 我确保opencv是由安装
import cv2 并检查我可以从文档运行几个例子。
现在我下载caffe，正确configurationmakefile.config并运行make all。 我得到非常奇怪的错误：

那家伙怎么了？ 请注意，我原来有anaconda3和编译caffe但成功，但我在python3下面临caffe问题，所以我不得不删除它，并尝试使用python 2.7设置为anaconda。
当然，我已经确保libpng16.so.16在anaconda：
maxkhk@maxkhk-X550DP:~/anaconda$ find -name libpng16.so.16 ./pkgs/libpng-1.6.17-0/lib/libpng16.so.16 ./lib/libpng16.so.16 maxkhk@maxkhk-X550DP:~/anaconda$
我search了这个错误，但没有发现与caffe有关的任何内容。
我遇到了同样的问题，我通过在我的Makefile.config中添加-rpath来修复它：
LINKFLAGS := -Wl,-rpath,$(HOME)/anaconda/lib
我认为这是正确的修复，因为它（-rpath）告诉GCC在哪里可以找到库（libjpeg，libpng）的其他库（在这种情况下，opencv）所依赖的库。
Per @cel建议 –
ldd libopencv_highgui.so
显示这个lib依赖的文件。 他们中的一些人（不是libpng！）位于我没有包含在makefile.config文件夹中。 将文件夹包含到MakeFile构建成功后。 注意：在建立caffe之后，你可能不会去Spyder进入PythonPath管理器，并将caffe的文件夹添加进去（或者如果你不使用anaconda \ spyder，就把它包含到pythonpath中）。
添加
LINKFLAGS := -Wl,-rpath,$(HOME)/anaconda/lib
在Makefile.config中工作。
