Mastering Computer Vision with TensorFlow 2.x

Downloading weights

The code for downloading the weights is as follows:

from tensorflow.keras.applications import VGG16from keras.applications.vgg16 import preprocess_inputfrom tensorflow.keras.applications.resnet50 import ResNet50, preprocess_inputfrom tensorflow.keras.applications import InceptionV3from keras.applications.inception_v3 import preprocess_input

The preceding code performs the following two tasks:

1. The weights will be downloaded as follows as part of the output from the preceding code:

• Download VGG16 weight, the *.h5 file
• Download Resnet50 weight, the *.h5 file
• Download InceptionV3 weight, the *.h5 file

2. It does the preprocessing of the image to normalize the current image to the ImageNet RGB dataset. Since the model is ...
