RETURNN - RWTH extensible training framework for universal recurrent neural networks,
is a Theano/TensorFlow-based implementation of modern recurrent neural network architectures.
It is optimized for fast and reliable training of recurrent neural networks in a multi-GPU environment.
Features include:
- Mini-batch training of feed-forward neural networks
- Sequence-chunking based batch training for recurrent neural networks
- Long short-term memory recurrent neural networks
including our own fast CUDA kernel - Multidimensional LSTM (GPU only, there is no CPU version)
- Memory management for large data sets
- Work distribution across multiple devices
- Flexible and fast architecture which allows all kinds of encoder-attention-decoder models

Here is the video recording of a RETURNN overview talk <https://www-i6.informatik.rwth-aachen.de/web/Software/returnn/downloads/workshop-2019-01-29/01.recording.cut.mp4>_
(slides <https://www-i6.informatik.rwth-aachen.de/web/Software/returnn/downloads/workshop-2019-01-29/01.returnn-overview.session1.handout.v1.pdf>,

hosted by eBay).
There are many example demos <https://github.com/rwth-i6/returnn/blob/master/demos/>_
which work on artificially generated data,
i.e. they should work as-is.
There are some real-world examples <https://github.com/rwth-i6/returnn-experiments>_
such as setups for speech recognition on the Switchboard or LibriSpeech corpus.
Some benchmark setups against other frameworks
can be found here <https://github.com/rwth-i6/returnn-benchmarks>.
The results are in the RETURNN paper 2016 <https://arxiv.org/abs/1608.00895>.
Performance benchmarks of our LSTM kernel vs CuDNN and other TensorFlow kernels
are in TensorFlow LSTM benchmark <https://returnn.readthedocs.io/en/latest/tf_lstm_benchmark.html>__.
There is also a wiki <https://github.com/rwth-i6/returnn/wiki>.
