【问题描述】：

我通过 apt install 命令在我的 Ubuntu v18 VM 上安装了 caffe-cpu。我正在努力找出安装目录的位置，如果我错了，请纠正我，但我相信没有安装目录。我正在尝试执行的我的 NN 模型需要来自 caffe 的构建工具的路径。我怎样才能得到这个？我在任何地方都没有看到有关此的任何信息。

【问题讨论】：

dpkg-query -L caffe-cpu 会告诉您安装的包apt 将其文件放在哪里。见askubuntu.com/questions/32507/…

标签： python linux ubuntu caffe pycaffe

【解决方案1】：

caffe 的 Ubuntu 软件包在 /usr/bin 中安装 caffe 可执行文件。您想要的特定文件位于caffe-tools-cpu，而不是caffe-cpu。

来自https://packages.ubuntu.com/bionic/amd64/caffe-tools-cpu/filelist：
