TensorFlow Tutorial: tf.data for TFRecord

In this tutorial, we'll explore how to use TensorFlow's tf.data API to efficiently load and process TFRecord data for training deep learning models. The tf.data API provides a powerful and flexible way to build high-performance data input pipelines for TensorFlow. Code Examples 1. Importing Libraries import tensorflow as tf 2. Reading TFRecord Files # Define the list of TFRecord files tfrecord_files = [ "file1.tfrecord" , "file2.tfrecord" , "file3.tfrecord" ] # Define the feature description for parsing feature_description = { "image" : tf.io.FixedLenFeature([], tf.string), "label" : tf.io.FixedLenFeature([], tf.int64), } # Define a function to parse the TFRecord def parse_tfrecord(example_proto): return tf.io.parse_single_example(example_proto, feature_description) # Create a dataset from the TFRecord files dataset = tf.data.TFRecordDataset(tfrecord_files) # Map the parsing function to the datas...

PyTorch Tutorial: DALI Data Loader for NPZ Data

In this tutorial, we'll explore how to use NVIDIA DALI (Data Loading Library) with PyTorch to efficiently load and preprocess NPZ (NumPy Archive) data for training deep learning models. DALI is a powerful library that accelerates data loading and preprocessing, making it ideal for handling large datasets.
