TX1入门教程软件篇-安装Caffe

说明：

  • 介绍如何在TX1上安装caffe

步骤：

  • 建立dl目录，下载安装脚本：
mkdir dl
cd dl
git clone https://github.com/jetsonhacks/installCaffeJTX1.git
cd installCaffeJTX1
  • 设置CPU and GPU clocks为最大：
$ sudo ./jetson_clocks.sh
  • jetson_clocks.sh脚本内容为：

安装nvcaffe:

问题：

  • 问题1：可能会在runtest卡住

  • 解决：在下载的安装脚本中make -j4 runtest前增加make -j4 test ，在caffe目录下make clean再执行安装命令

  • 问题2：caffe目录下，没有build目录

  • 解决：进入caffe目录执行：

    cd ~/caffe
    mkdir build
    cd build
    cmake ..
    cd ..
