After running

python confusion_matrix.py --detections_record=data/train.record --label_map=data/object_detection.pbtxt --output_path=confusion_matrix.csv

I got this error:

WARNING:tensorflow:From confusion_matrix.py:38: tf_record_iterator (from tensorflow.python.lib.io.tf_record) is deprecated and will be removed in a future version.
Instructions for updating:
Use eager execution and:
`tf.data.TFRecordDataset(path)`
