This is the repository for the Master of Applied Data Science course "Data Analysis & Visualisation", previously known as "Data Mining & Exploration".

1. First, make sure you have python >= 3.10. You can check the version with python --version.
2. Make sure you installed pdm , eg with pip install pdm.
3. Install the dependecies by navigating the the root where the pyproject.toml is located and run pdm install.

Download a chat from Whatsapp and put it in the data/raw folder. Rename the file to `chat.txt' and run the following command just once:

eval $(pdm venv activate)

This will activate your virtual environment. After this, you can run the preprocessor with the following command:

python src/preprocess.py --device ios

Change ios to android if you have an android device.

You should see some logs, like this:
