Confusion with opennmt-tf #122

Closed nashid closed 4 years ago

nashid commented 4 years ago

I am a bit confused when to adopt which framework with keras? Also what is difference between opennmt-tf (https://github.com/OpenNMT/OpenNMT-tf) vs nmt-keras?

Also how does it differ than simply using https://github.com/keras-team/keras/blob/master/examples/lstm_seq2seq.py

Well, now that Keras has been integrated into TF, it's all a little bit convoluted. NMT-Keras uses an extended version of keras (NOT tf.keras).

OpenNMT-tf makes use of tf.keras, as part of the TF ecosystem.

https://github.com/keras-team/keras/blob/master/examples/lstm_seq2seq.py is a simple Seq2Seq model, that lacks several features, such as attention mechanisms or beam search.
