download seq13

[wenjunj]

Thank you :)
I just want to download the sequence of the dataset, such as seq 13
but I failed ,like below,
the demo odometry.py needs any change?
File "pykitti-master/demos/demo_odometry.py", line 32, in
first_gray = next(iter(dataset.gray))
StopIteration
first_gray = next(iter(dataset.gray))
first_cam1 = next(iter(dataset.cam1))
first_rgb = dataset.get_rgb(0)
first_cam2 = dataset.get_cam2(0)
third_velo = dataset.get_velo(2)
