WebMay 5, 2024 · flow_from_directory() returns an array of batched images and not Tensors. We can checkout a single batch using images, labels = train_data.next(), we get image shape - (batch_size, target_size, target_size, rgb). Training time: This method of loading data gives the second highest training time in the methods being dicussesd here. WebThis has to do with the different shapes you are feeding into the cm function. You are passing training_set.classes (which will have length n_classes) and y_pred (which will have length n_samples).Instead of passing training_set.classes you should therefore pass the real labels for each sample, so that this vector also has a length of n_samples.
