Any tutorials that you can recommend?

So I understood the attention mechanism ( Bahdanau Attention,
2017 paper) and I was looking for the implementation of the paper
and then I landed on the tensorflow website which has a tutorial on
attention mechanism. Nut Frankly speaking, I found it very hard to
understand the code. Are there any tutorials that you can share
that will help me to understand the code of the attention
mechanism.
