The validity of pretrained weight was confirmed, even though the image size was 64x64. ImageNet is an image database organized according to the WordNet hierarchy (currently only the nouns), in which each node of the hierarchy is depicted by hundreds and thousands of images. PyTorch Geometric is a geometric deep learning extension library for PyTorch.. And the best way to get deeper into Deep Learning is to get hands-on with it. Imageio is a Python library that provides an easy interface to read and write a wide range of image data, including animated images, volumetric data, and scientific formats. You see, just a few days ago, François Chollet pushed three Keras models (VGG16, VGG19, and ResNet50) online — these networks are pre-trained on the ImageNet dataset, meaning that they can recognize 1,000 common object classes out-of-the-box.
