The code is written in Python using Tensorflow 2.3.0. Usually the code is also compatible with some other versions of Tensorflow 2.x. A rough specification of each function/script is given in the corresponding header.

The script run_example.py reproduces the examples from Section 4.1 and 4.2 and the script run_grads.py reproduces the examples from Section 4.3 of [1].

Note that the code is highly experimental, far from optimized and only sparsely commented, so use it with care.
