<caffe學習筆記> caffe訓練日誌輸出

problem：caffe 訓練日誌輸出

solution：運用tee命令

 eg：./build/tools/caffe train \ --solver=models/bvlc_reference_caffenet/solver.prototxt 2>&1| tee yourpath/caffe.log

1. tee的意思就是命令行信息重定向的命令

2. 2>&1的意思是錯誤的信息也當成標準信息輸出，這樣能夠保證輸出log信息的完整性。

這是2>&1的詳細解釋：

File descriptor 1 is the standard output (stdout).
File descriptor 2 is the standard error (stderr).

Here is one way to remember this construct (although it is not entirely accurate): at first, 2>1 may look like a good way to redirect stderr to stdout. However, it will actually be interpreted as "redirect stderr to a file named 1". & indicates that what follows is a file descriptor and not a filename. So the construct becomes: 2>&1.
