issue in utils.read_calib_file

[songanz]

Hi,
The read_calib_file() cannot read the calib file in KITTI object data correctly, since there is a "/n" at the end

I haven't encountered any problems with this function. Are you getting an error message when you load data?

I encounter the same problem and the error is "ValueError: need more than 1 value to unpack".
Adding a check condition if len(line) < 2: continue before key, value = line.split(':', 1) (around Line 74 in utils.py) should help.
