TensorFlow Datasets
Ready-to-use datasets for TensorFlow and machine learning.
π TensorFlow Datasets Overview
TensorFlow Datasets (TFDS) is an open-source library that provides a curated collection of ready-to-use datasets optimized for TensorFlow and other machine learning frameworks. It addresses the common challenge of accessing clean, standardized, and versioned datasets, enabling researchers, educators, and engineers to focus on model development rather than data wrangling. With support for multi-modal data including images, text, audio, and video, TFDS is a versatile tool in the AI ecosystem.
π οΈ How to Get Started with TensorFlow Datasets
Getting started with TFDS is straightforward:
import tensorflow_datasets as tfds
import tensorflow as tf
# Load the MNIST dataset with train and test splits
(ds_train, ds_test), ds_info = tfds.load(
'mnist',
split=['train', 'test'],
shuffle_files=True,
as_supervised=True,
with_info=True,
)
# Normalize images
def normalize_img(image, label):
return tf.cast(image, tf.float32) / 255.0, label
ds_train = ds_train.map(normalize_img).cache().shuffle(1000).batch(32).prefetch(tf.data.AUTOTUNE)
ds_test = ds_test.map(normalize_img).batch(32).prefetch(tf.data.AUTOTUNE)
# Build a simple model
model = tf.keras.Sequential([
tf.keras.layers.Flatten(input_shape=ds_info.features['image'].shape),
tf.keras.layers.Dense(128, activation='relu'),
tf.keras.layers.Dense(10),
])
model.compile(
optimizer='adam',
loss=tf.keras.losses.SparseCategoricalCrossentropy(from_logits=True),
metrics=['accuracy'],
)
# Train the model
model.fit(ds_train, epochs=5, validation_data=ds_test)
This example shows how easy it is to load, preprocess, and train on datasets using TFDS.
