ValueError: Error when checking input: expected dense_39_input to have shape (6,) but got array with shape (1,)

Question

This is my first post in stackoverflow. So I have built a Neural Network predicting AirBnb prices , with accuracy 77 % but I am struggling to input an array so the model can give me a prediction. (Jupyter Notebook)

xa = np.array([3, 1, 1, 28, 1, 1])
print(xa.shape)
(6,)

ynew = nn3.predict(xa[0:1])
print(ynew)

and after line 5 the error is appearing

ValueError: Error when checking input: expected dense_39_input to have shape (6,) but got array with shape (1,)

With ynew = nn3.predict(xa) I have the same error.

Thank you!

Why the [0:1]? Did you use 6 arguments when you built the network? — B. Go, Dec 15 '19 at 18:39

Try this :

xa = numpy.array([[3, 1, 1, 28, 1, 1]])
ynew = nn3.predict(xa)
print(ynew)
