TensorFlow 1 version View source on GitHub

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:

    from keras import backend as K 
    kvar = K.variable(np.random.random((2,3))) 
    kvar_ones = K.ones_like(kvar) 
    K.eval(kvar_ones) 
        array([[ 1.,  1.,  1.], 
               [ 1.,  1.,  1.]], dtype=float32)
