Generator #4
Description
https://github.com/tensorflow-northwest/kaggle/blob/master/projects/imaterialist_2018/notebooks/iMaterlialist_NASNet_Train.ipynb loads one train/test data set.
Need to extend the generator to load all train/test files located on Google Drive at bit.ly/tfnw-k-1 .... It should load individual data files to avoid saturating memory.
