Start with build-ai-agent-langgraph-ollama setup. Install dependencies first. Create a clean project directory. Set up your virtual environment to keep things isolated. In practice, test each component before moving on. For example, this saves hours of debugging later. Moreover, use version control from the start.

from langchain_community.llms import Ollama
from langchain.chains import RetrievalQA
from langchain_community.vectorstores import Chroma

llm = Ollama(model="llama3.1:8b")
vectorstore = Chroma(persist_directory="./db", embedding_function=embeddings)
qa = RetrievalQA.from_chain_type(llm, retriever=vectorstore.as_retriever())
result = qa.invoke({"query": "Your question here"})
