tf.keras.backend.ones_like
Instantiates an all-ones variable of the same shape as another tensor.
tf.keras.backend.ones_like(
x, dtype=None, name=None
)
Arguments |
x | Keras variable or tensor. |
dtype | String, dtype of returned Keras variable. None uses the dtype of x. |
name | String, name for the variable to create. |
Returns |
A Keras variable with the shape of x filled with ones. |
Example:
kvar = tf.keras.backend.variable(np.random.random((2,3)))
kvar_ones = tf.keras.backend.ones_like(kvar)
tf.keras.backend.eval(kvar_ones)
array([[1., 1., 1.],
[1., 1., 1.]], dtype=float32)
