INFO:tensorflow:Error reported to Coordinator: <class 'tensorflow.python.framework.errors_impl.NotFoundError'>, tfrecords/kitti_train.tfrecord

[w5688414]

when I run this command:
jupyter notebook notebooks/ssd_kitti_tests.ipynb

I met a problem when I run the following code:

`# with queues.QueueRunners(sess):

Start populating queues.

coord = tf.train.Coordinator()
threads = tf.train.start_queue_runners(coord=coord)`

and the error information is:

INFO:tensorflow:Error reported to Coordinator: <class 'tensorflow.python.framework.errors_impl.NotFoundError'>, tfrecords/kitti_train.tfrecord [[Node: parallel_read/ReaderReadV2 = ReaderReadV2[_device="/job:localhost/replica:0/task:0/cpu:0"](parallel_read/TFRecordReaderV2, parallel_read/filenames)]]

Can anyone help me?
