This repository contains reference implementations of various LangChain agents as Streamlit apps including:
basic_streaming.py
: How to do streaming with a simple app usinglangchain.chat_models.ChatOpenAI
mrkl_demo.py
: An agent that replicates the MRKL demominimal_agent.py
: A minimal agent with search (requires settingOPENAI_API_KEY
env to run)search_and_chat.py
: A search-enabled chatbot that remembers chat history
Apps feature LangChain 🤝 Streamlit integrations such as the Callback integration.
This project uses Poetry for dependency management.
# Create Python environment
$ poetry install
# Install git pre-commit hooks
$ poetry shell
$ pre-commit install
# Run mrkl_demo.py or another app the same way
$ streamlit run streamlit_agent/mrkl_demo.py
We plan to add more agent examples over time - PRs welcome
