Lab Classifying Images
In this project, learners will be testing their newly-acquired Python coding skills by using a trained image
classifier. They will need to use the trained neural network to classify images of dogs (by breeds) and compare the output with the known dog breed classification. Learners will have a chance to build their own functions, use command line arguments, test the runtime of the code, create a dictionary of lists, and more.
