tf.debugging.assert_scalar(
    tensor,
    name=None,
    message=None
)

This function raises ValueError unless it can be certain that the given tensor is a scalar. ValueError is also raised if the shape of tensor is unknown.

Args:

  • tensor: A Tensor.
  • name: A name for this operation. Defaults to "assert_scalar"
  • message: A string to prefix to the default message.

Returns:

The input tensor (potentially converted to a Tensor).

Raises:

  • ValueError: If the tensor is not scalar (rank 0), or if its shape is unknown.
