Exercise 1 - Verify Ollama

Goal: Confirm Ollama is running and the two models you need are available.

Before you start​

Make sure you have run:

ollama serve
ollama pull nomic-embed-text
ollama pull llama3.2

Assignment​

Open 01_verify_ollama.py and work through the following steps:

  1. Send a GET request to http://localhost:11434/api/tags and print the response.
  2. Parse the JSON and extract just the model names from the list.
  3. Check that both nomic-embed-text and llama3.2 appear in that list. Print a clear pass/fail message for each.
  4. If a model is missing, print the exact ollama pull command the user needs to run.

Run it:

python exercises/01_verify_ollama.py

You should see two green-light messages. If you see a connection error, Ollama is not running - start it with ollama serve.

Thinking questions​

  • What HTTP status code do you get from /api/tags when Ollama is running? What do you get when it is not?
  • What does the full JSON response look like? What other information is in it besides model names?
