caffe学习笔记13-caffe写训练日志

caffe写训练日志(output.m)

  在train的时候最后加 tee $folder_prefix/caffe.log，就可以重定向到文件夹了。

  1. 你可以从系统 /tmp 文件夹获取，名字是什么 caffe.ubuntu.username.log.INFO.....之类。（参考output.m）

  2. 在train的时候最后加 2>&1 | tee $folder_prefix/caffe.log，就可以重定向到文件夹了。

output.m:

% Well, this is a function that write the

% iteration vs accurancy

% iteration vs loss

% To a file
