Divide Tfrecord Into Multiple With Code Examples

With this text, we’ll have a look at some examples of Divide Tfrecord Into Multiple issues in programming.

import tensorflow as tf

raw_dataset = tf.knowledge.TFRecordDataset("input_file.tfrecord")

shards = 10

for i in vary(shards):
    author = tf.knowledge.experimental.TFRecordWriter(f"output_file-part-{i}.tfrecord")
    author.write(raw_dataset.shard(shards, i))

By investigating quite a lot of use eventualities, we had been in a position to display methods to clear up the Divide Tfrecord Into Multiple downside that was current.

What is the benefit of TFRecord?

Using the TFRecord format has many benefits: Efficiency: Data within the TFRecord format can take up much less area than the unique knowledge. Fast I/O: TensorFlow can learn knowledge within the TFRecord format with parallel I/O operations. This may be very helpful when you find yourself working with GPU or TPU gadgets.24-Aug-2021

What is a TFRecord?

The TFRecord format is a straightforward format for storing a sequence of binary data. Protocol buffers are a cross-platform, cross-language library for environment friendly serialization of structured knowledge. Protocol messages are outlined by . proto recordsdata, these are sometimes the best approach to perceive a message kind.08-Jun-2022
