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:

Update the requirements.in file with the new package or version.
Install pip-tools if you haven't already:
```
pip install pip-tools
```
Compile the new requirements.txt file:
```
pip-compile requirements.in
```
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.
