我正在尝试从Ubuntu 16.04（4.15.0-39-通用x86_64 GNU / Linux）上的源（从https://github.com/BVLC/caffe来的git pull）中安装Caffe。
遇到此错误时，看来我没有通过boost库（或其他库）得到它：

这是生成后的带有“ Caffe配置摘要”的我的cmake输出：
https://pastebin.com/raw/1r7WXzbj
我使用指定bootstrap.sh的python3解释器从源代码安装了boost 1.68。
./b2 install之后一切正常。
我想知道我错了吗？
我还想知道为什么它说在找到Boost version: 1.68.0的同时无法找到和。
其次，由于伯克利视觉实验室是该领域的顶级实验室之一，并且vision and learning组成为了“ bair”，所以我不知道为什么开发的活动并不活跃。 >
