tensorflow c++踩的坑

Posted on | Edited on

问题1：头文件找不到

  • 编译tensorflow源码时添加环境变量
    几种方式：
  1. 打开 /etc/profile 文件，在末尾添加 export PATH=(自己的路径)$PATH
  2. 把编译好的文件复制到 /usr/local/install/ 中
  • 编译时tensorflow的一些头文件找不到
    看错误提示，到相应的文件夹下看看有没有相应的文件
  1. 存在，说名环境变量没有设置正确
  2. 若不存在，看看是否存在同样文件名的 .proto 文件，使用 protoc 生成 .cpp 和 .h 文件
  3. 若也不存在 .proto文件，使用 find |grep 文件名，找到相应文件，可以复制到错误提示的文件夹中，或者把当前路径添加到环境变量中(原文件中使用的名字需要作相应的改动改动)

自己写的文件中方法找不到

ctrl + 点击，跳转到源文件中查看源码，若却是不存在，使用 grep 在源文件中搜索定义的地方，然后在自己的代码中替换,并作相应修改

protoc 命令使用踩过的坑

  1. 版本不正确
    把目前使用的protoc 卸载，然后安装相应的版本，如果使用 apt remove protoc 卸载失败，可以直接在/usr/local/include/ 中把 头文件文件夹删了，在 /usr/local/bin/ 中把 protoc 删除
  2. 找不到依赖的 .proto 文件，使用 protoc -I=相应路径 这种方式(如：sudo protoc -I=/usr/local/include/tf/ -I=. –cpp_out=. cluster.proto )
