You can train a model using these datasets by passing them to model.fit (shown later in this tutorial). Plt.imshow(images.numpy().astype('uint8')) Here are the first nine images from the training dataset. You can find the class names in the class_names attribute on these datasets.

You will use 80% of the images for training and 20% for validation. It's good practice to use a validation split when developing your model. Create a datasetĭefine some parameters for the loader: batch_size = 32 Let's load these images off disk using the helpful tf._dataset_from_directory utility. Here are some roses: roses = list(data_dir.glob('roses/*')) There are 3,670 total images: image_count = len(list(data_dir.glob('*/*.jpg')))Įach directory contains images of that type of flower. import pathlibĪrchive = tf._file(origin=dataset_url, extract=True)ĭata_dir = pathlib.Path(archive).with_suffix('')Ģ28813984/228813984 - 1s 0us/stepĪfter downloading (218MB), you should now have a copy of the flower photos available. Note: all images are licensed CC-BY, creators are listed in the LICENSE.txt file. The flowers dataset contains five sub-directories, one per class: flowers_photos/ This tutorial uses a dataset of several thousand photos of flowers. If you would like to use Nvidia GPU with TensorRT, please make sure the missing libraries mentioned above are installed properly.
