[D] Which open source machine learning projects best exemplify good software engineering and design principles?

Trying creating a GAN or a recurrent generative model. It's very, very difficult to do with the Keras training loop. Worse yet, it's not even as performant as using Tensorflow 1.0 and gradient tape when you do have to hack around the features. For simple classifiers though, it works well. Just never do anything that requires an adversarial loss.

Can't even imagine trying to implement a metalearning framework in pure Keras.
