TensorFlow Serving client hosted by Flask web framework

This is an extension of my TensorFlow Serving test project. It introduces a Flask web server that hosts TensorFlow serving client. It receives REST requests to predict Street View House Numbers, translates them into protobufs and sends to a TensorFlow server via gRPC for prediction by GAN model.
Mentioned GAN model is trained using semi-supervised learning technique and based on the model taught at Udacity Deep Learning Foundations course. The original Jupyter Notebook can be found at GitHub.
