我正在按照以下链接进行caffe安装： https://gist.github.com/arundasan91/b432cb011d1c45b65222d0fac5f9232c
我正在使用Ubuntu 18.04 LTS
$ make runtest -j 8
我收到以下错误：
.build_release/tools/caffe
.build_release/tools/caffe: error while loading shared libraries:
libprotobuf.so.15: cannot open shared object file: No such file or directory
Makefile:532: recipe for target 'runtest' failed
make: *** [runtest] Error 127

我发现这是一个python问题。所以我做到了：
$ which protoc
/home/<user_name>/anaconda2/bin/protoc
$ protoc --version
libprotoc 3.5.1
我检查了conda，正在使用conda的最新protobuf。另外，如果我降级protobuf，“ caffe / python / requirements.txt”中的列表也不会通过。谢谢您的帮助。
