I came across Deepo [http://ufoym.com/deepo/] recently and was amazed at the level of simplicity that is now available if one wants to start tinkering with deep learning. Check out the deep learning libraries you can setup with a single command. Head over to their Quickstart [http://ufoym.
Develop an image labeling service using a pre-trained deep neural network and scale the service by deploying to the cloud.
It isn't often that you need to label lots of images. But when the need arises you can use many of the pre-trained deep neural network models available for image labeling tasks. One of the most popular ones is ResNet50 and keras provides a convenient [https://keras.io/applications/#resnet]
