tf.zeros_like

View source

Creates a tensor with all elements set to zero.

Aliases:

  • tf.compat.v2.zeros_like
tf.zeros_like(
    input,
    dtype=None,
    name=None
)

Given a single tensor (tensor), this operation returns a tensor of the same type and shape as tensor with all elements set to zero. Optionally, you can use dtype to specify a new type for the returned tensor.

For example:

tensor = tf.constant([[1, 2, 3], [4, 5, 6]])
tf.zeros_like(tensor)  # [[0, 0, 0], [0, 0, 0]] with dtype=int32

If dtype of input `tensor` is `float32`, then the output is also of `float32`
tensor = tf.constant([[1.0, 2.0, 3.0], [4, 5, 6]])
tf.zeros_like(tensor)  # [[0., 0., 0.], [0., 0., 0.]] with dtype=floa32

If you want to specify desired dtype of output `tensor`, then specify it in
the op tensor = tf.constant([[1.0, 2.0, 3.0], [4, 5, 6]])
tf.zeros_like(tensor,dtype=tf.int32)  # [[0, 0, 0], [0, 0, 0]] with
dtype=int32

Args:

  • input: A Tensor.
  • dtype: A type for the returned Tensor. Must be float16, float32, float64, int8, uint8, int16, uint16, int32, int64, complex64, complex128, bool or string.
  • name: A name for the operation (optional).

Returns:

A Tensor with all elements set to zero.
