these are my two arrays that I have defined:

xs = np.array([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], dtype= float)
ys = np.array([100.0, 150.0, 200.0, 250.0, 300.0, 350.0], dtype=float)

model.fit method is giving me a value error this is how i fit:

model.fit(xs, ys, epochs = 1000)
the error says

anyone else has come across this error:

ValueError: Exception encountered when calling layer "sequential_16" (type Sequential).

Input 0 of layer "dense_16" is incompatible with the layer: expected min_ndim=2, found ndim=1. Full shape received: (None,)

Make sure your model has one input layer the definition can be similar to

model = tf.keras.Sequential([tf.keras.layers.Dense(units=1, input_shape=[1])])
