Function Calling Starter project

This is a starter project for the function calling project here: https://hackmd.io/@timothy1ee/Hk1jhHCaA

It starts you off with a basic Chainlit app that streams responses, and maintains chat history. There is an initial system prompt that sets up an AI movie assistant that can generate a function call to fetch now playing movies.

There is a helper file that provides the required movie functions.

To run the app, use the following command:

chainlit run app.py -w

Installation

1. Create a virtual environment

First, create a virtual environment to isolate the project dependencies:

python -m venv .venv

2. Activate the virtual environment:

• On Windows:

  .venv\Scripts\activate

• On macOS and Linux:

  source .venv/bin/activate

3. Set up environment variables

Copy the .env_sample file to .env:

cp .env_sample .env

Then edit the .env file and add your API keys:

• OPENAI_API_KEY: Your OpenAI API key
• TMDB_API_ACCESS_TOKEN: Your TMDB API access token
• SERP_API_KEY: Your SERP API key
• LANGCHAIN_API_KEY: Your LangChain API key

4. Install dependencies

Install the project dependencies from the requirements.txt file:

pip install -r requirements.txt

Updating dependencies

If you need to update the project dependencies, follow these steps:

1. Update the requirements.in file with the new package or version.

2. Install pip-tools if you haven't already:

   pip install pip-tools

3. Compile the new requirements.txt file:

   pip-compile requirements.in

4. Install the updated dependencies:

   pip install -r requirements.txt

This process ensures that all dependencies are properly resolved and pinned to specific versions for reproducibility.
