上传问题错误

您好，我在上传文件后提示了如下错误，请问是为什么 ValueError: The constructor now takes in a list of Node objects. Since you are passing in a list of Document objects, please use from_documents instead.

具体错误为 ERROR: Exception in ASGI application Traceback (most recent call last): File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\uvicorn\protocols\http\h11_impl.py", line 429, in run_asgi result = await app( # type: ignore[func-returns-value] File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\uvicorn\middleware\proxy_headers.py", line 78, in call return await self.app(scope, receive, send) File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\fastapi\applications.py", line 276, in call await super().call(scope, receive, send) File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\starlette\applications.py", line 122, in call await self.middleware_stack(scope, receive, send) File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\starlette\middleware\errors.py", line 184, in call raise exc File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\starlette\middleware\errors.py", line 162, in call await self.app(scope, receive, _send) File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\starlette\middleware\cors.py", line 92, in call await self.simple_response(scope, receive, send, request_headers=headers) File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\starlette\middleware\cors.py", line 147, in simple_response await self.app(scope, receive, send) File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\starlette\middleware\exceptions.py", line 79, in call raise exc File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\starlette\middleware\exceptions.py", line 68, in call await self.app(scope, receive, sender) File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\fastapi\middleware\asyncexitstack.py", line 21, in call raise e File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\fastapi\middleware\asyncexitstack.py", line 18, in call await self.app(scope, receive, send) File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\starlette\routing.py", line 718, in call await route.handle(scope, receive, send) File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\starlette\routing.py", line 276, in handle await self.app(scope, receive, send) File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\starlette\routing.py", line 69, in app await response(scope, receive, send) File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\starlette\responses.py", line 174, in call await self.background() File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\starlette\background.py", line 43, in call await task() File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\starlette\background.py", line 28, in call await run_in_threadpool(self.func, *self.args, *self.kwargs) File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\starlette\concurrency.py", line 41, in run_in_threadpool return await anyio.to_thread.run_sync(func, args) File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\anyio\to_thread.py", line 33, in run_sync return await get_async_backend().run_sync_in_worker_thread( File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\anyio_backends_asyncio.py", line 2106, in run_sync_in_worker_thread return await future File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\anyio_backends_asyncio.py", line 833, in run result = context.run(func, *args) File "C:\Users\15030\Desktop\chatdoc-master\server\main.py", line 98, in file_task doc.build_index(res["doc_type"]) File "C:\Users\15030\Desktop\chatdoc-master\server\doc_util.py", line 101, in build_index index = GPTSimpleVectorIndex(documents) File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\llama_index\indices\vector_store\base.py", line 44, in init super().init( File "C:\Users\15030\Desktop\chatdoc-master\venv\lib\site-packages\llama_index\indices\base.py", line 51, in init raise ValueError( ValueError: The constructor now takes in a list of Node objects.
