    Return True if all elements of the input tensor are true along the
    specified axis.

    Args:
        x: A float or tensor.
        axis (optional): The axis of interest.
        keepdims (optional): If this is set to true, the dimension of the tensor
                             is unchanged. Otherwise, the reduced axis is removed
                             and the dimension of the array is 1 less.

            bool: 'all' applied to all elements in the tensor

            tensor (of bytes): 'all' applied to the elements in the tensor
