Excellent work - got a working example going!
Thank you so much for this video! You are Awesome ❤
thank you
Thank You from a NEW Subscriber !
Awesome, thank you!
Good stuff!
thanks
Graph RAG cost a lot indeed on API calls.
One of your best video I do believe.thanks a lot
thank you
Thank you for the video.
You're welcome
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.
Good tutorial. Thank you for sharing the code.
Thank you
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 ?
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.
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.
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.
Thanks for the video.
Can i use mxbai from ollama for embedding purposes... or is there a limitation on that?
sure you can use it.
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
It has its own built-in vector store. For migration, I would suggest installing it from scratch in cloud.
hey, i got it working, but it is giving out of context answers when I do local search, any idea what could be wrong?
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.
Yes, you would have to run the index procedure. Thanks.
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?
plz check the logs in output directory and see what the error is. Also make sure that command is correct
Does this solution still works for anybody ?
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.
hi i have a doubt about this graphRag can it be run in aws ec2 instance
yes
@@fahdmirza if possible please make a video ,that will be helpful for me
Thanks for sharing! ... Anyone else suffering from this error: "openai.APITimeoutError: Request timed out." ??
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?
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.

Same issue here...below states to use "ollama" as API key. In which file should this be indicated?
@fahdmirza FYI on your webpage linked w/ the commands and code snippets for this vid, you have "model: nomic_embed_text" yet "ollama pull nomic-embed-text" which leads to: Error embedding chunk {'OpenAIEmbedding': 'Error code: 404 - {\'error\': "model \'nomic_embed_text\' not found, try pulling it first"}'}
first of all thank you,
ZeroDivisionError: Weights sum to zero, can't be normalized when using local method
which model you are using?
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.
I am also getting same error while using local method
same error with groq api llama3 8b and nomic embed text, any solution to this?
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()
...
```
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.
That can be done too in various ways, but the purpose of this video to do it all in Ollama. Thanks for comment.
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
Can you create a video on how to use GraphRAG with the GROQ API? Looks like nobody has done it yet. Thank you.
yeah just did. Thanks.
@@fahdmirza Thanks, I appreciate your work.
Kindly could you show, how to use this Graph RAG with CSV data. Will be super helpful
Its the same process as any data. The cleaner your data is, the better your responses will be.
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??
Langchain+neo4j+chroma = MS graphrag …. Correct?
Please explore this repo github.com/microsoft/graphrag for underlying tech. Thanks.
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

SUCCESS: Global Search Response: In the story, the main themes revolve around the transition of young people from formal education to practical work, specifically through apprenticeship under Ebenezer Scrooge. This transition is evident in various scenes and actions [Data: Scenes (1, 2, 3); Actions (4)].
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)]. It is also suggested that Scrooge may act as a mentor or supervisor to these apprentices during this period [Data: Relationships (1-23)].
The young people are involved in various activities related to their apprenticeship, which could include tasks such as bookkeeping, accounting, or business management [Data: Actions (1-5)]. However, the exact nature of these activities is not explicitly detailed in the provided data.
It is important to note that the information provided is based on the analysis of multiple reports and does not necessarily cover all aspects of the story. For a more comprehensive understanding, additional research or analysis may be required.
