Create TensorFlow JS model to do inference

Setup a TensorFlowJS model to do inference in the browser

• load pretrained weights
• make predictions on new images

Looks like there are streamlined steps to export keras model written in python to tensorflow.js! https://js.tensorflow.org/tutorials/import-keras.html

Adding to that, this would be how you could take a pretrained MobileNet and save it in a format that tensorflow.js can use.

import tensorflowjs as tfjs
from keras.applications.mobilenet import MobileNet

model = MobileNet(weights='imagenet')
tfjs.converters.save_keras_model(model, 'test_model')
