I found this lacks of the label, so it won't be fit into the model using fit_generator. We use a sampling rate as one as we dont want to skip any samples in the datasets. 1 Answer Sorted by: 1 When you are using a pre-trained model, you should use it's specific pre-processing function, Below is an example for resnet50. Alternatively, if your input data is stored in a file in the recommended TFRecord format, you can use tf.data.TFRecordDataset (). This is available in tf. In this article, we will see how to subclass the tf. class to implement custom data generators. series series. For example, to construct a Dataset from data in memory, you can use tf. () or tf. (). L.append(os.path.join(folders, filename))ĭef generate_data(directory, batch_size): Standard Keras Data Generator Keras provides a data generator for image datasets.
