I am getting this error for lstm_forward and I’m not sure why. Help will be appreciated!
You probably fetch shapes incorrectly:
# Retrieve dimensions from shapes of x and parameters['Wy'] (≈2 lines)
i.e., n_a, m, and T_x have the wrong values.
Also your initialization of c and y are incorrect.

a=np.zeros([n_a,m,Tx])

Yes, that’s correct. But I think the problem for the student who posted this thread was that one of the elements of the array was not a scalar integer (e.g. was an array itself or perhaps a float value).
