	""" Allows for command line hyperparameter inputs to models

	Description
	------------

	--image_size: Sets up the size of a square image, default is 32*32 for CIFAR10
	--features : Sizes of convolutional feature maps, the first one ought to be 3 corresponding to RGB channels
	--norm : Batch-normalisation boolean flag (default is True)
	--ptype : Specifies pooling type:
		- 'max' (default) for max pooling
		- 'average' for average pooling
	--aug : Data augmentation boolean flag (default is False)
	--dropout : Set dropout probability, p = 1.0 (default) implies nothing is dropped out
	--optype : Specifies optimizer type, default set to 'ADAM', if anything else is chosen, RMSProp is used
	--hsize : Specifies the size of the hidden layer in the fully connected layer that follows conv layers
	--bsize : Specifies the batch size for training

	Note
	----
	Assertions and exceptions are not added, please be careful in passing arguments. If in doubt, please allow default values.
	For non-square images appropriate modifications need to be made in helper_nn.py
