Reproduction

数据格式为Alpaca，提供了system字段：

SFT设置的template为qwen：

执行的时候，从日志中查看example，提示还是使用的默认system：

<|im_start|>system
You are a helpful assistant.<|im_end|>
<|im_start|>user
xxxx<|im_end|>
<|im_start|>assistant
yyyyy<|im_end|>
```text

即You are a helpful assistant.

查看qwen的template，是增加了system处理的：
register_template(
name="qwen",
format_user=StringFormatter(slots=["<|im_start|>user\n{{content}}<|im_end|>\n<|im_start|>assistant\n"]),
format_assistant=StringFormatter(slots=["{{content}}<|im_end|>\n"]),
format_system=StringFormatter(slots=["<|im_start|>system\n{{content}}<|im_end|>\n"]),
format_function=FunctionFormatter(slots=["{{content}}<|im_end|>\n"], tool_format="qwen"),
format_observation=StringFormatter(
slots=["<|im_start|>user\n<tool_response>\n{{content}}\n</tool_response><|im_end|>\n<|im_start|>assistant\n"]
),
format_tools=ToolFormatter(tool_format="qwen"),
default_system="You are a helpful assistant.",
stop_words=["<|im_end|>"],
)
