Asserts that the given tensor is a scalar.

tf.compat.v2.debugging.assert_scalar(
    tensor,
    message=None,
    name=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.

This is always checked statically, so this method returns nothing.

Args:

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

Raises:

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