OutOfRangeError (see above for traceback): RandomShuffleQueue '_1_shuffle_batch/random_shuffle_queue' is closed and has insufficient elements (requested 8, current size 0)
[[Node: shuffle_batch = QueueDequeueManyV2[component_types=[DT_FLOAT, DT_FLOAT], timeout_ms=-1, _device="/job:localhost/replica:0/task:0/device:CPU:0"](shuffle_batch/random_shuffle_queue, shuffle_batch/n)]]

How to deal with this issue when I train the model in kitti ???

I have encountered the same problem. Maybe you can check if the image suffix in the "kitti_train_files.txt" is "jpg", but the suffix of the kitti images is "png".

@jiansheng1993 @qiutzh @yamnaben I had this same problem and I resolved it, though I'm not sure its universal. I think the main problem from this means that queue wants to dequeue but it can't. This means its something wrong with requesting the training file (so check your file names in the train image txt file).

The problem in the end was in line 100 of monodepth_dataloader.py.

path_length = string_length_tf(image_path)[0]

If you request the variable through sess.run, you will see that it does not work
This should be changed to:

path_length = tf.size(tf.string_split([image_path],""))

This gives a correct int when requested through sess.run.

Hopefully this works for you!
