File Open Mode when a worker read a file that filename is sent from a slave.

[taeguk]

When a worker read a file that filename is sent from a slave, what mode do we use to open a file?

In current,

• "rb" where session file
• "rt" where result file

I think this will be okay in now.
But, in tensorflow object code template, we must remember and follow the assumption of file data type for continuous "okay".
