You will need to install a few dependencies before executing the script:
pip3 install -r requirements.txtIf that doesn't work, try this:
pip3 install --user -r requirements.txtThe --user specifies your home directory
For Arch Linux:
pip3 install -r requirements.txtOr:
pip install --user -r requirements.txtNow you need to run the following:
python pattern-finder.py / python3 pattern-finder.py (the latter if you are using Python 3 via Homebrew on Mac OS)
