However, pure performance isn’t the only advantage of the TFRecord file format. It is optimized for use with Tensorflow in multiple ways. To start with, it makes it easy to combine multiple datasets and integrates seamlessly with the data import and preprocessing functionality provided by the library. Especially for datasets that are too large to be stored fully in memory this is an advantage as only the data that is required at the time (e.g. a batch) is loaded from disk and then processed. Another major advantage of TFRecords is that it is possible to store sequence data — for instance, a time series or word encodings — in a way that allows for very efficient and (from a coding perspective) convenient import of this type of data.

A TFRecords file represents a sequence of (binary) strings. The format is not random access, so it is suitable for streaming large amounts of data but not suitable if fast sharding or other.. Spread the love. If you are working with images, Especially for datasets that are too large to be stored in memory then binary data takes up less space on disk, takes less time to copy and read The data looks very similar — in the previous example we had a set of features, where each feature consisted of a single list. Each entry in the list represented the same information for a different movie, for instance the movie rating. This didn’t change, but now we also have Actors, which is a list of the actors with a role in the movie. This type of data cannot be stored in a tf.train.Example. We need a different type of structure for this kind of data, and Tensorflow provides it in the form of tf.train.SequenceExample. In contrast to tf.train.Example, it does not store a list of bytes, floats or int64s, but a *list of lists* of bytes, floats or int64s, and is thus suited for our dataset.

  3. g the samples..
  4. So, there are a lot of advantages to using TFRecords. But where there is light, there must be shadow and in the case of TFRecords the downside is that you have to convert your data to this format in the first place and only limited documentation is available on how to do that. An official tutorial and a number of articles about writing TFRecords exist, but I found that they only got me covered part of the way to solve my challenge.
  5. If you are working with large datasets, using a binary file format for storage of your data can have a significant impact on the performance of your import pipeline and as a consequence on the training time of your model. Binary data takes up less space on disk, takes less time to copy and can be read much more efficiently from disk. This is especially true if your data is stored on spinning disks, due to the much lower read/write performance in comparison with SSDs.
  6. Try this code to convert a directory of images to TFRecords: def _int64_feature(value): return tf.train.Feature(int64_list=tf.train.Int64List(value=[value]))
