 """Update one binary quadratic model from another. Args: bqm (:class:`.BinaryQuadraticModel`):
 The updating binary quadratic model. Any variables in the updating model are added to the updated model. Values of biases and the offset in the updating model are added to the corresponding values in the updated model. ignore_info (bool, optional, default=True):
 If True, info in the given binary quadratic model is ignored, otherwise :attr:`.BinaryQuadraticModel.info` is updated with the given binary quadratic model's info, potentially overwriting values. Examples: This example creates two binary quadratic models and updates the first from the second. 1.25 False True 2.0 """
