Jiaming Yuan	d33854af1b	[Breaking] Accept multi-dim meta info. (#7405) ... This PR changes base_margin into a 3-dim array, with one of them being reserved for multi-target classification. Also, a breaking change is made for binary serialization due to extra dimension along with a fix for saving the feature weights. Lastly, it unifies the prediction initialization between CPU and GPU. After this PR, the meta info setter in Python will be based on array interface.	2021-11-18 23:02:54 +08:00
