I am follow the issue paper writtend as the IE Address:

## Introduction

In this tutorial we will see how DIGITS may be used to train an Object Detection neural network using the Caffe back-end.
In this particular example, we will train the network to detect cars in pictures taken from a dashboard camera.
During inference, object detection will be materialized by drawing bounding rectangles around the detected objects.

## Dataset creation

But I get a big problem.
terminal show as follow :

(help) @MS-8CC99:~/digits/examples/object-detection$ ./prepare_kitti_data.py
Extracting zipfiles ...

Traceback (most recent call last):
  File "./prepare_kitti_data.py", line 189, in <module>
    use_symlinks=(not args.no_symlinks),
  File "./prepare_kitti_data.py", line 78, in split_by_video
    for old_image_fname in os.listdir(os.path.join(training_dir, 'image_2')):
OSError: [Errno 2] No such file or directory: 'kitti-data/raw/training/image_2'

Smoe nice guy help fix this ERROR environment.
Thanks you.

Try running the script as
./prepare_kitti_data.py --no-symlinks
and see if that fixes it.

I try but is not work. Can you find anyother way fix the problem.

Thanks you.
