[BUG] - <title> without docker error

[Smile-L-up]

Description

Thank you very much for open-sourcing such a great project. I installed without docker. Deploy according to the following steps:

# optional (setup env)
conda create -n kotaemon python=3.10
conda activate kotaemon

# clone this repo
git clone https://github.com/Cinnamon/kotaemon
cd kotaemon

pip install -e "libs/kotaemon[all]"
pip install -e "libs/ktem"

View and edit your environment variables (API keys, end-points) in .env.

(Optional) To enable in-browser PDF_JS viewer, download PDF_JS_DIST and extract it to libs/ktem/ktem/assets/prebuilt

Then run python app.py. When I visit http://localhost:7860/, an error is reported.

error
Connection errored out.

Looking forward to your reply.

pydantic.errors.PydanticSchemaGenerationError: Unable to generate pydantic-core schema for <class 'starlette.requests.Request'>. Set `arbitrary_types_allowed=True` in the model_config to ignore this error or implement `__get_pydantic_core_schema__` on your type to fully support it.

If you got this error by calling handler(<some type>) within `__get_pydantic_core_schema__` then you likely need to call `handler.generate_schema(<some type>)` since we do not call `__get_pydantic_core_schema__` on `<some type>` otherwise to avoid infinite recursion.

Hi @Smile-L-up please ensure that you install from a fresh environment. Could you run the Docker approach successfully?

This is a freshly installed Linux env looks like. Please check if there is any dependencies are mismatched. requirements.lock.txt

Hi @Smile-L-up, it can be an issue of FastAPI or Pydantic. Can you reinstall these dependencies: pip install -U fastapi==0.112.1 pydantic==2.9.1 and run python app.py again?

[Smile-L-up]

你好@Smile-L-up，这可能是 FastAPI 或 Pydantic 的问题。您可以重新安装这些依赖项： pip install -U fastapi==0.112.1 pydantic==2.9.1然后python app.py再次运行吗？

Thanks for your guidance, it's working fine now.
