大家好：我希望只要点击按钮cell运行，否则不运行。但因为(prompt_files.path()这个file_browser的值一变就运行了，原来结果就没保留了

prompt_exists = prompt_files.name() is not None

single = len(prompt_files.value) == 1

mo.stop(not one_report.value,
# mo.md("选择提示词文件后点击生成报告"),
)

ragtasks = [rag(**task) for task in get_rag_tasks(prompt_files.path(index=-1))]

rag_outputs = await asyncio.gather(*ragtasks)
report = pd.DataFrame(rag_outputs, columns=["task", "reply", "context"])
report
