tf.keras.backend.zeros_like

TensorFlow 1 version View source on GitHub

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

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

Arguments:

  • x: Keras variable or Keras tensor.
  • dtype: dtype of returned Keras variable. None uses the dtype of x.
  • name: name for the variable to create.

Returns:

A Keras variable with the shape of x filled with zeros.

Example:

from tensorflow.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)
