towardsdatascience.com › loading-custom-imageLoading Custom Image Dataset for Deep Learning Models: Part 1 Aug 19, 2020 · We can also convert the input data to tensors to train the model by using tf.cast() history = model.fit(x=tf.cast(np.array(img_data), tf.float64), y=tf.cast(list(map(int,target_val)),tf.int32), epochs=5) We will use the same model for further training by loading image dataset using different libraries. Loading image data using PIL Introduction to the Python Deep Learning Library TensorFlow TensorFlow is an open source library for fast numerical computing. It was created and is maintained by Google and released under the Apache 2.0 open source license. The API is nominally for the Python programming language, although there is access to the underlying C++ API. Unlike other numerical libraries intended for use in Deep Learning like ...

› guide › datatf.data: Build TensorFlow input pipelines | TensorFlow Core Jun 09, 2022 · The tf.data API enables you to build complex input pipelines from simple, reusable pieces. For example, the pipeline for an image model might aggregate data from files in a distributed file system, apply random perturbations to each image, and merge randomly selected images into a batch for training.
