The values if n_x and X.shape[1] is ok, bit the assert function has an error

If your n_x of 1 and X.shape[1] of 30 are correct, then your Y_hat needs to be of shape (1, 30). The Y_hat value that you printed out looks like a scalar.

I printed the Y_hat value before the assert function.

There seems to be no reason that the assert function should not work with :
Y_hat = 0.517…
n_x = 1
X.shape[1] = 30

Your Y_hat does not look like a 1×30 array.
