Error when running 'roslaunch ocrtoc_task trigger.launch task_index:=0-0'

[Skylark0924]

When running roslaunch ocrtoc_task trigger.launch task_index:=0-0, I got this error:

process[trigger-1]: started with pid [1072]
Traceback (most recent call last):

I rosrun that py script only, and got this:

Could you please tell what is the problem?

I cloned it in a Windows and transfer it to my Ubuntu server, so this error is caused by the wrong code style in these two systems. After I downloaded it directly on ubuntu, the problem was solved.

The same problem still exists in version 2.1.
This problem does not exist in the previous version
