Classify images in the three Kaggle datasets on the course website 
with convolutional networks. You may use transfer learning. Your
goal is to achieve above 90% accuracy on the test/validation datasets.

You may access the datasets directly from my home directory on
lochness:

/home/u/usman/cs_677_datasets

Submit your assignments as two files train.py and test.py. Make
train.py take two inputs: the input training directory
and a model file name to save the model to. 

python train.py train <model file>

Make test.py take three inputs: the test directory 
and a model file name to load the model. 

python test.py test <model file>

The output of test.py is the test error of the data which is
the number of misclassifications divided by size of the test set.

Copy both your programs and model file to your AFS 
course folder /afs/cad/courses/ccs/s20/cs/677/850/<UCID>. The 
assignment is due on July 18th 2020.
