Week 1 assignment 3, exercise 1

Course Q&A Deep Learning Specialization Sequence Models

I am stuck at exercise 1 of assignment 3 of week 1. Seems not supposed to…

I am seeing the error below when running the unit test

AttributeError: The layer “reshape” has multiple inbound nodes, with different output shapes. Hence the notion of “output shape” is ill-defined for the layer. Use get_output_shape_at(node_index) instead.

I examined my code and hint multiple times . Could not figure out what is wrong. I notice the dimension of x and the output of reshaper(x) are:

(None, 90)
(None, 1, 90)

instead of what the comment says “Use reshaper to reshape x to be (1, n_values)”

but I followed the instruction from " Select the ‘t’ time-step vector from X" to get the slice…

Thanks for the hint!
