tf.keras.backend.zeros_like

tf.keras.backend.zeros_like(
    x,
    dtype=None,
    name=None
)

Defined in tensorflow/python/keras/_impl/keras/backend.py.

Instantiates an all-zeros variable of the same shape as another tensor.

Arguments:

  • x: Keras variable or Keras 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 zeros.

Example: python >>> from keras import backend as K >>> kvar = K.variable(np.random.random((2,3))) >>> kvar_zeros = K.zeros_like(kvar) >>> K.eval(kvar_zeros) array([[ 0., 0., 0.], [ 0., 0., 0.]], dtype=float32)
