I cannot for the life of me figure out what the compiler dislikes about my code. Does anyone know what’s the matter? I included debugging prints.
I think the most likely problem is that eitiher your code for “x = …” or "a_prev = … " is incorrect.

The problem could be on the second iteration, when ‘x’ is re-defined inside the loop.

Right! I added the following print statement in the loop right before the line that “throws” in your test case:
print(f"Wax {Wax.shape} x {x.shape} Waa {Waa.shape} a_prev {a_prev.shape}")
Here’s the output I see in the first few iterations:
vocab_size = 27
Wax (100, 27) x (27, 1) Waa (100, 100) a_prev (100, 1)
y.shape (27, 1)
Wax (100, 27) x (27, 1) Waa (100, 100) a_prev (100, 1)
y.shape (27, 1)
So it looks like there are at least two problems with your code:
You are apparently substituting a_prev for x.
Your a_prev is a 1D array when it should be a 2D array.
So how could that happen?
That was it. I hadn’t redefined x correctly later in the loop. That was throwing off my code, and I didn’t think to look there. Thanks.
