It's all about line breaks.

It's all about linefeeds-general Linux technology-Linux programming and kernel information. For more information, see the following. Recently, the CRFs feature selection algorithm has been improved. Because the source code runs in Linux, the text is thrown into the linux virtual machine, and a strange error occurs. The error message is displayed, indicating that the format is incorrect, I ran to the Group for help, and there were a lot of coders. I was told that the encoding was different. I tried to convert it to UTF-8, or it was wrong. I finally found the problem. The line feed for windows was 0D0A, unix only has a line break of 0A, leading to a non-empty line. An error is prompted. At the prompt, I used the dos2unix command to convert the text. Finally, I am very happy. The problem still occurs.
