In this video, I will be showing you how to create an artificial intelligence agent that will be able to use all of the tools that we provide it with. That's right, we will create and AI agent & give it various tools for it to use selectively based on the task at hand.
Note: This video refers to llamaindex version 0.9. On Feb 12th, 2024 llamaindex version 0.10 was released which is mostly the same but has some added functionality :)

If you are running this blindly without using Tim's requirements file, please note that due to security `from llama_index.query_engine import PandasQueryEngine` is no longer the right import, try pip installing `llama-index-experimental` and then using the PandasQueryEngine class from `from llama_index.experimental.query_engine import PandasQueryEngine`. This is for py3.10. Finally, the PromptTemplate class is now at `from llama_index.core import PromptTemplate`. The documentation will really help though. Thanks Tim.

To add context in order to refer to previous response like "save the response to my notes", you can add context = " ".join([f"role: {exchange['role']} content: {exchange['content']}" for exchange in st.session_state.messages]) response = agent.query(context + " " + prompt)

Thanks, Tim. I've noticed that many of the RAG examples available on RU-vid primarily focus on enhancing the model using PDFs, CSVs, or plain text. However, in practice, a significant portion of business data is stored in relational databases, such as Oracle or SQL Server. Could you provide an example demonstrating how RAG can be applied to data from relational databases?

@pntra1220 4 месяца назад

Hi Tim, first of all, great tutorial! I wanted to ask you if you know if it's possible or efficient to use llama index to do RAG over 300k pages of pdfs. I've been researching and a lot of people say that I will have to fine tune the embeddings models and use one from hugging face. Also to make the results better, use metadata. However, I am wondering if using llama index is the correct approach or if I will need to create my own RAG system. Thank you for taking the time to read this.

@SivaMahadevan-ny7vm 2 месяца назад

This tutorial is super helpful. Thanks Tim. I was able to get the app working. when I ask a question about canada or population, Agent is able to answer the question by looking at the PDF, CSV etc.. But when I ask a question like "what is solar eclipse", the agent is still able to answer the question. How can I prevent it from happening ? I just want answers that are available in the documents.

@mbasemhassen2947 3 месяца назад

I think that the issue was that the function was not called in openai section so for me, the issue was model was not being used for instance in the 5 or 7 line of code in main the code which ends with input openai is not working because this is not a function which is why the model section near the end was not working so if you want this code to run that I think function needs to be defined for it

@malikanaser8251 Месяц назад

Hi man, you are the best, I wish if it was about extracting data from text or pdf and also harnessing data from agents LLM to store it in KG and make LLM query from it, all the video I watched about that were poor and not a practical solution, either they doesn't work or poor result or use paid software or don't accumulate data in the KG database with no duplicate... Man you are the one for this project, if you did it I unsure you your channel will be on fire.

@neilpayne8244 3 месяца назад

Thanks for the great vid. i tried following along but getting too many import errors. i also tried building a new virtual env, then installed the modules from your requirements.txt mentioned in this thread, and that also now doesnt work (llama_index tries to load pkg_resources which is not found).

@bhasadish 4 месяца назад

if you pass context history with the new prompt only then would it be able to save to note. Passing context history to LLM is an integral part of any RAG otherwise it looses context.

Question : once loading a vector store , how can we output a dataset from the store to be used as a fine tuning object ?

@egericke123 2 месяца назад

It doesn't save a note using the previous prompt because I think it is lost. I think you are calling a new instance of the model each time you give a new prompt. So you would have to update or append prompt outside the while loop to get it to remember the entire conversation... But I could definitely be wrong, just my intuition :P

@zengxuezhi Месяц назад

Thanks Tim, this is really informative video. Just have a question for this. In your code, the LLM model is OpenAI by default. I tried using a local LLM model such as llama (using "codellama-7b-instruct.Q8_0.gguf' loaded by LlamaCPP), and leave everything else the same as your code. But, it won't produce the desired result as your code shows. Can you have another video using a local LLM model rather than OPENAI that achieves the same functionality of Python AI Agent? Thanks in advance!
