This example demonstrates how to use langchain and langchain-openai in Python to connect to the adl-server. It sends a simple "Hello" message to the ADL Server's OpenAI-compatible chat completions endpoint.

• Docker and Docker Compose installed.
• Python 3.8 or higher.
• pip package manager.

First, start the ADL Server using Docker Compose in the parent directory:

docker-compose up -d

This will start the ADL Server on port 8080.

1. Ideally, create a virtual environment:

python3 -m venv .venv
source .venv/bin/activate  # On Windows, use .venv\Scripts\activate

2. Install dependencies:

pip install -r requirements.txt

Execute the main script:

python main.py

The script will:

1. Load environment variables.
2. Initialize a ChatOpenAI client pointing to http://localhost:8080/v1 (the ADL Server address).
3. Send a "Hello" message.
4. Print the response from the server.

You should see output similar to:

Connecting to ADL Server at http://localhost:8080/v1...
Sending message: 'Hello'

Response from ADL Server:
Hello there! How can I help you today?
