I am hopelessly lost trying to understand the shape of data coming in and out of an LSTM.
Most attempts to explain the data flow involve using randomly generated data with no real meaning, which is incredibly unhelpful.
Those examples that use real data, like this Udacity notebook 50 on the topic do not explain it well and do not generalize the concept to other kinds/shapes of data beyond strings of text.
This post 30 asks the identical question I have. No attempt at an answer was ever made, except that of the OP, who was unsure if his conclusion was correct.
So, what I’m asking is this: Can someone provide a simple, concrete example of using an LSTM  with:

“real” data one dimension (one variable).
“real” data with more than one dimension (multiple variables).

I would greatly appreciate it!
