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
)

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.

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)
