How to inspect a Tensorflow .tfrecord file?

Found it!

import tensorflow as tf

for example in tf.python_io.tf_record_iterator("data/foobar.tfrecord"):
    print(tf.train.Example.FromString(example))

You can also add:

from google.protobuf.json_format import MessageToJson
...
jsonMessage = MessageToJson(tf.train.Example.FromString(example))
