Ragby: Retrieval-Augmented Generation (RAG) By Yourself

• A collection of RAG-related methods

-----------

STEP 1) Import & Initialize:

from verba.OllamaHelper import Ragby

ragby = Ragby(chat_model = "llama3", embedding_model = "llama3")

STEP 2) Create Chunks:

• First place your input data file (.txt or .pdf) in a directory named data
• Run:

# for .txt files:
chunks_obj, chunks_path = ragby.make_chunks("my-txt-file.txt")

# for .pdf files:
chunks_obj, chunks_path = ragby.make_chunks_pdf("my-pdf-file.pdf")

• A directory named chunks will be created, containing the two returned objects

STEP 3) Create Embeddings:

• Run:

embeddings_path = ragby.make_embeddings(chunks_obj, "my-txt-file.txt")

• A directory named embeddings will be created, containing the returned object

STEP 4) Create a System Prompt that is relevant to your output:

SYSTEM_PROMPT = "You are a helpful assistant who answers questions using only the provided CONTEXT. Be as concise as possible. If you are unsure, just say 'I don't know'.\n\nCONTEXT:\n"

STEP 5) Run:

CHAT = ragby.chat(
    user_prompt = "What is the summary of this article?", 
    system_prompt = SYSTEM_PROMPT, 
    text_chunks_path = chunks_path, 
    text_embeddings_path = embeddings_path, 
)

print(CHAT)
