TensorFlow proved to be very successful with many AI tasks. One of the most popular in computer vision in the ImageNet exercise. The exercise is to test the model against the database if the images and their proper labels.
Once trained it can be used to classify new examples. To make things easier instead of building the model, packaging and maintaining it yourself, one can build the docker image. Katacoda offers the
katacoda/tensorflow_serving so there is no need for us to create one for the examples.
