yolov3部署GPU版问题及解决方案

1 编译错误

1.1 错误信息

xdq:darknet xindq$cmake
/bin/sh: 1: nvcc: not found
Makefile:88: recipe for target 'obj/convolutional_kernels.o' failed
make: *** [obj/convolutional_kernels.o] Error 127

1.2 原因

• 未配置cuda环境变量
• 查看CUDA版本
  cat /usr/local/cuda/version.txt

1.3 解决方案

• 编辑配置文件
  sudo vim /etc/profile
• 添加cuda路径配置

export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

• 编译路径文件
  source /etc/profile
• 编译darknet

 make clean
 make

2 命令不起作用

2.1 提示信息

Command 'ls' is available in '/bin/ls'
The command could not be located because '/bin' is not included in the PATH environment variable.
ls: command not found

2.2 原因

• 路径配置有错误

2.3 解决方案

• 编辑/etc/profile
  /usr/bin/sudo /usr/bin/vim /etc/profile
• 修改路径配置

export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

• 重启服务
  /usr/bin/sudo sbin/reboot
