ResNet-152 in Keras

This is an Keras implementation of ResNet-152 with ImageNet pre-trained weights. I converted the weights from Caffe provided by the authors of the paper. The implementation supports both Theano and TensorFlow backends. Just in case you are curious about how the conversion is done, you can visit my blog post for more details.

"""
Sometimes in your Django model you want to raise a ``ValidationError`` in the ``save`` method, for
some reason.
This exception is not managed by Django Rest Framework because it occurs after its validation 
process. So at the end, you'll have a 500.
Correcting this is as simple as overriding the exception handler, by converting the Django
``ValidationError`` to a DRF one.

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

List of nationalities

It's time someone compiled a list of nationalities to use within a web application. This gist attempts to make a first move at that.
