Recipe Objective

What is TFrecordwriter?

As we have discussed earlier only about TFRecord, the TFRecord writer is a class which writes the record to a TFRecord file. The writer is used to write the serialized examples to a file for later consumption. Lets understand this with practical implementation.

Access YOLO OCR Character Recognition Project with Source Code

Step 1 - Import library

import tempfile import tensorflow as tf import os import numpy as np

Step 2 - Define path

path = os.path.join(tempfile.gettempdir(), "My.tfrecords") np.random.seed(0)

Step 3 - Write the records

with tf.io.TFRecordWriter(path) as TF_writer: for values in range(10): a, b = np.random.random(), np.random.random() bytes_record = tf.train.Example(features=tf.train.Features(feature={ "a": tf.train.Feature(float_list=tf.train.FloatList(value=[a])), "b": tf.train.Feature(float_list=tf.train.FloatList(value=[b])), })).SerializeToString() TF_writer.write(bytes_record) print("This is the output for TF_writer:",values)

This is the output for TF_writer: 9
