Flow from dataframe
WebAug 30, 2024 · In this tutorial we'll see how we can use the Keras ImageDataGenerator library from Tensorflow to create a model for classifying images. We'll be using the Image Data Generator to preprocess our images and also to feed our images into the model using the flow_from_dataframe function. The data we'll be using comes from a Kaggle … WebSo, to make a dataset of dictionary-examples from a DataFrame, just cast it to a dict before slicing it with Dataset.from_tensor_slices: numeric_dict_ds = tf.data.Dataset.from_tensor_slices( (dict(numeric_features), target)) Here are the first three examples from that dataset: for row in numeric_dict_ds.take(3):
