what's the difference between HuggingFaceCausalLM and HuggingFacewithChatTemplate ?

Not sure what's the differents between these two models.

Also if I use the old meta template such as:

_meta_template = dict(
begin='<|im_start|>system\nxxx<|im_end|>',
end="<|im_start|>bot\n"
round=[
dict(role='HUMAN', begin='<|im_start|>user\n', end='<|im_end|>'',),
dict(role='BOT', begin='<|im_start|>bot\n', end='<|im_end|>''),
],
)

it will get error when using HuggingFacewithChatTemplate:

[rank0]:   File "/user/opencompass/opencompass/models/huggingface_above_v4_33.py", line 71, in _convert_chat_messages
[rank0]:     if skip_empty_prompt and not item['prompt']:
[rank0]: TypeError: string indices must be integers

which the current item is "<|im_start|>system\nxxx<|im_end|>"
