[Bugfix][Kimi-VL] Set pad_token_id explicitly in KimiVLConfig - #65174
Conversation
`KimiVLConfig` passed `pad_token_id` to `super().__init__` as a keyword
argument. With the dataclass-based `PreTrainedConfig`, `pad_token_id` is
not a declared field. It throws out:
TypeError: __init__() got an unexpected keyword argument 'pad_token_id'

Overview
KimiVLConfigpassedpad_token_idtosuper().__init__as a keyword argument. With the dataclass-basedPreTrainedConfig,pad_token_idis not a declared field.Claims
TypeError: __init__() got an unexpected keyword argument 'pad_token_id'raised whenKimiVLConfigis constructed on aPreTrainedConfigbase that does not forward unknown keyword arguments.pad_token_idis now assigned explicitly onKimiVLConfigbefore thesuper().__init__call, so the attribute exists regardless of how the base class handles unused kwargs.pad_token_id=continue to work.pad_token_idvalue itself; the fix only removes the reliance on an implicitsetattrpath.Validation
KimiVLConfigon a base that rejects unknown kwargs (or monkeypatch the base__init__to not forward extras); observeTypeError: __init__() got an unexpected keyword argument 'pad_token_id'.config.pad_token_idreturns the supplied value.Details
PreTrainedConfigis a dataclass, andpad_token_idis not a declared field on it; the field is only used byKimiVLConfigitself.I've checked the code on huggingface and #16387, it can be confirmed that MoonshotAI has modified the base
