  • Big training data (58.2 GB, 7 million products each having up to 4 images)
  • A lot of difficult categories (different styles of books and CDs)
  • Variable number of images (1-4) for each product

Requirements

  • keras
  • tensorflow
  • pandas
  • numpy
  • scipy
  • pymongo
  • scikit-image
  • pillow
  • cython
  • h5py
