A question about C4W4 Assignment Time series prediction

Course Q&A TensorFlow Developer Professional Sequences, Time Series and Prediction
1

In the Assignment, it uses daily-min-temperatures data to predict a future daily temperature. The model outputs the next day prediction of shape (None, 1).

Any one know why the output shape is (None, 1), not just (1,) ?

2

Maybe for the case when batches are used.

Thanks, Gent!

Got that now.
