	if self.meta_instruction:
	ret += f'{self.system}:{self.meta_instruction}{self.eosys}'

这个地方多了个冒号

lmdeploy/lmdeploy/model.py

Lines 265 to 273 in 4d1fdfe

	assert self.capability == 'chat', \
	f'{type(self).__name__} has no capability of {self.capability}'
	if sequence_start:
	return f'{self.system}{self.meta_instruction}{self.eosys}' \
	f'{self.user}{prompt}{self.eoh}' \
	f'{self.assistant}'
	else:
	return f'\n{self.user}{prompt}{self.eoh}' \
	f'{self.assistant}'

这个地方少了 289 行的逻辑。就是如果调messages2prompt的接口的话，不传meta_instruction可以不拼f'{self.system}{self.meta_instruction}{self.eosys}'，但是上面decorate_prompt是一定会拼f'{self.system}{self.meta_instruction}{self.eosys}'
