Assuming your output state size is h
. You will generate nxh
for n
data points if return_sequences
is false
. On the other hand you would be having nxtxh
dimensional array as output if return_sequences
is set to true
. Here t
is the number of timestamps in each data point.

So choosingreturn_sequences
=True/False
doesn't change the 3D array output shape?

It does. In false case you got last hidden state out. But in true case every internal hidden state gets released out.
