GraphRAG with Ollama, entity_extraction directory is not empty but errors come... Columns must be same length as key . How to solve?

[@sergeziehi4816]

Graph RAG cost a lot indeed on API calls.
One of your best video I do believe.thanks a lot

[@fahdmirza]

thank you

[@georgeknerr]

Excellent work - got a working example going!

Hi @Fahad, This is simply excellent stuff. keep going

[@framefact4636]

Thank you!, I am curious about visualize the knowledge graph, how to visualize it?

[@Ayush-tl3ny]

Thank you so much for this video! You are Awesome ❤

[@fahdmirza]

thank you

[@TheStuzenz]

Nice video Fahd - GraphRAG looks really good! I plan on trying it out tonight. The querying against it looks quite expensive though. I wonder if they have built in any caching approach with the query engine. I guess I better do some reading.

Thank You from a NEW Subscriber !

You're welcome

[@lisag.9863]

Thank you for the great video! I got an error that says that "No text files found in input" even though my input does have a clear *.txt file. Do you know what could be the problem?

[@vitaliiturchenko8101]

Thanks Fahd for your hard work! Very interesting!!! 1) is it possible to link GraphRag to the local ChromaDB database ? 2) local search also works in your method or only global search ?

[@fahdmirza]

thaks. You would have to hack the source code to change the vector store. Yes local search also worked. Just have to replace global keyword with local.

[@chrishau5556]

Does this solution still works for anybody ?

[@mikew2883]

Excellent tutorial! I was wondering if you had a chance to work with the "graphrag-accelerator" Github project that Microsoft also put out. It says it can be used as an API that has all the GraphRAG functionality but in an API.

[@fahdmirza]

I think graphrag-accelerator requires Azure. If its API based, I would rather go directly to OpenAI and I have already done a video on it.

[@richardobiri2642]

Awesome

[@fahdmirza]

thanks mate

[@ibc--mediators]

Hi Fahd …, 1. Where does graphrag store the vectors and graphs in? I.e on local machine… 2. how do we transfer the entire graphrag app from the local machine to into the cloud….once we are done with ingestion and testing

[@fahdmirza]

It has its own built-in vector store. For migration, I would suggest installing it from scratch in cloud.

[@Thinker-i8d]

perfect job. but when i try to use graphrag with ollama, error happened. logs.json shows: {"type": "error", "data": "Error Invoking LLM", "stack": "Traceback (most recent call last), and the index-engine.log shows:graphrag.index.reporting.file_workflow_callbacks INFO Error Invoking LLM
does anyone know how to fix this error??

[@padhuLP]

Good tutorial. Thank you for sharing the code.

[@fahdmirza]

Thank you

[@AdityaSingh-in9lr]

hey, i got it working, but it is giving out of context answers when I do local search, any idea what could be wrong?

[@zhengwu-jw6fm]

When run the code 'python3 -m graphing.index --root./rattiest',showers occurred during the pipeline run, See logs for more details.What to solve this problem?

[@fahdmirza]

plz check the logs in output directory and see what the error is. Also make sure that command is correct

[@tollington9414]

thanks

[@EngineerMustaphaSahli]

Thanks for sharing! ... Anyone else suffering from this error: "openai.APITimeoutError: Request timed out." ??

[@TheMariolino2005]

Great job! What if I want to add another document to the GraphRAG? Should I repeat the --init procedure or is there any other method? Great video, thank you.

[@fahdmirza]

Yes, you would have to run the index procedure. Thanks.

[@revanthphanisaimedukonduru1177]

Thanks for latest information, Can you please also add reference for this point , "GraphRAG don't support if its less than 32k context?" 7:22

That's on basis of trial at the moment of creating video.

ZeroDivisionError: Weights sum to zero, can't be normalized when using local method

[@fahdmirza]

which model you are using?

[@aravindchakrahari8966]

I got the same error as well while using local method. And also, Error embedding chunk {'OpenAIEmbedding': "'NoneType' object is not iterable"}
I am using mistral and nomic-embed-text:latest for embeddings.

[@ayushjadia6527]

I am also getting same error while using local method

[@Ayush-tl3ny]

same error with groq api llama3 8b and nomic embed text, any solution to this?

[@gnsnwr]

Issue is that `--method local` does not work out of the box with open source embedding models.
It is because of the way how OpenAI's `text-embedding-3-small` model is working. It is using token IDs as input, while open source models like `nomic-embed-text` are working with text as input.
So you need to convert token IDs to text before using open source models.
Solution is to add one line to package's `graphrag/query/llm/oai/embedding.py` "embed" function :
```python
...
def embed(self, text: str, **kwargs: Any) -> list[float]:
"""
Embed text using OpenAI Embedding's sync function.
For text longer than max_tokens, chunk texts into max_tokens, embed each chunk, then combine using weighted average.
Please refer to: github.com/openai/openai-cookbook/blob/main/examples/Embedding_long_inputs.ipynb
"""
token_chunks = chunk_text(
text=text, token_encoder=self.token_encoder, max_tokens=self.max_tokens
)
chunk_embeddings = []
chunk_lens = []
for chunk in token_chunks:
# decode chunk from token ids to text (added line after row 83)
chunk = self.token_encoder.decode(chunk)
try:
embedding, chunk_len = self._embed_with_retry(chunk, **kwargs)
chunk_embeddings.append(embedding)
chunk_lens.append(chunk_len)
# TODO: catch a more specific exception
except Exception as e: # noqa BLE001
self._reporter.error(
message="Error embedding chunk",
details={self.__class__.__name__: str(e)},
)
continue
chunk_embeddings = np.average(chunk_embeddings, axis=0, weights=chunk_lens)
chunk_embeddings = chunk_embeddings / np.linalg.norm(chunk_embeddings)
return chunk_embeddings.tolist()
...
```

[@aa-xn5hc]

API key for Ollama should be "ollama". also, no need to do the embeddings locally because their cost is not high. The main objective should be to to do the LLM part with Ollama and then enquire both globally and locally.

[@fahdmirza]

That can be done too in various ways, but the purpose of this video to do it all in Ollama. Thanks for comment.

[@davidbeauchamp5867]

would you change this in the .env file or directly in the setting.yaml. I have the same issue as above where _config.py requires API key

[@khriza4991]

Thank you for the video. I'm facing the same error as another commenter mentioned: '❌ Errors occurred during the pipeline run, see logs for more details.' Where can I find the logs?

[@fahdmirza]

Sure, go to this directory ~/ragtest/output/20240711-055438/reports . The date directory would vary as per your run. You would log files there. Thanks.

Can i use mxbai from ollama for embedding purposes... or is there a limitation on that?

You only did global search what about local. That is only half the rag. I got this far and thought you figured it out

Its the same process, you just need to replace global with local

During their apprenticeship, the young people are engaged in specific tasks or responsibilities that are likely related to Scrooge's business [Data: Actions (1-5)].
