A library for Keras for investigating architectures and parameters of sequential models.
(discontinuted) For more general approaches, see: Simple diagrams of convoluted neural networks
Both model.summary() and graph export were not enough - I wanted array dimensions, numbers of parameters and activation functions in one place.
I use it for didactic purpose.
- TODO
- Add ASCII art for more layers.
- Go beyond simple sequential models (e.g. to allow merge layers); any ideas how?
- Consider PRing to the main Keras repo, see #3873.
See this library in the wild, for example:
- Starting deep learning hands-on: image classification on CIFAR-10 - my post at deepsense.ai
- Cifar-10 Classification using Keras Tutorial at Plon.io
From PyPI:
pip install keras_sequential_ascii
Or from this repo:
pip install git+git://github.com/stared/keras-sequential-ascii.git
from keras_sequential_ascii import keras2ascii
keras2ascii(model)
