Knowledge Graph Builder App Local deployment

Neo4j Graph Platform
1

I am trying to deploy locally Knowledge Graph Builder App using instructions at

Here are my environment
MacBook Pro M3 18GB
macOS 15.1.1
Neo4j Desktop 1.6.1
created a sample database with APOC 5.24.2

Successfully installed frontend:
cd frontend
yarn
yarn run dev

For backend: no error
cd backend
python -m venv envName
source envName/bin/activate
pip install -r requirements.txt

until:
uvicorn score:app --reload

error message:
/Users/peterchan/llm-graph-builder/backend/envName/lib/python3.10/site-packages/pydantic/_internal/fields.py:161: UserWarning: Field "model_name" has conflict with protected namespace "model".

You may be able to resolve this warning by setting model_config['protected_namespaces'] = ().

To use it run pip install -U :class:~langchain-huggingface and import as from :class:~langchain_huggingface import HuggingFaceEmbeddings``.
embeddings = SentenceTransformerEmbeddings(

I am an archivist with very limited technical skills. I need to run a knowledge graph app locally because the data I am using is restricted by privacy and copyrights. Any help will be very much appreciated.

I updated the code from github which was updated 11 hrs ago. The previous are gone. But, I got following errors when I start "http://localhost:5173/" in a tab,

Now, no error in both frontend and backend.

However, I have This site can’t be reached
localhost refused to connect.
for http://localhost:5173/

I installed the same package in an Intel mac and it works. I think the code need changes for M3 mac.

5

I install node 20 and it works now.

Hey, I am trying the same thing. I am deploying the knowledge graph builder to run locally because of the privacy issues with my data. How did you do that??

7

There are instructions for local deployment: GitHub - neo4j-labs/llm-graph-builder: Neo4j graph construction from unstructured data using LLMs

I installed a local instance of the Knowledge Graph app. I can load files using "Drag and Drop" and the "Web Sources" tab. However, in the Preview Graph, only "Document & Chuck" appear and no entities. I used Graph Enhancement to add "movies" as a predefined schema, reprocess the file, and the result is still missing entities. I am wondering what went wrong.

9

There are also some more installation instructions here, besides the readme, which we just updated.

I want to use other LLMs via Ollama and put the following in .env file
LLM_MODEL_CONFIG_ollama_llama3="llama3,http :// localhost:11434"
Unfortunately, llama3 does not appear in the LLM Models in the bottom left-hand corner.
I tried LLM_MODEL_CONFIG_ollama_llama3="llama3,http :// host.docker.internal:11434" as well and got the same result.

11

I also try this and failed as well:
LLM_MODEL_CONFIG_ollama_<model_name>
#example
LLM_MODEL_CONFIG_ollama_llama3=${LLM_MODEL_CONFIG_ollama_llama3-llama3,
http:// host.docker.internal:11434}

I found this in backend terminal:
Failed to create GDS driver: The Graph Data Science library is not correctly installed on the Neo4j server.
Please refer to https: //neo4j.com/docs/graph-data-science/current/installation/.

2024-12-13 12:58:38,088 - Failed to create communities: The Graph Data Science library is not correctly installed on the Neo4j server.
Please refer to https: // Installation - Neo4j Graph Data Science.

I used https:/ /github.com/neo4j-labs/llm-graph-builder.git to install the app. Any suggestion on how to fix this issue?

I installed GDS Library via Neo4j desktop. But still no entity show.
