Open the tic-tac-toe notebook file:
You can do this by using VSCode's file explorer
Run the virtual environment setup script:
This script will:
Make sure you're in your project root directory when running this command!
In VS Code or Jupyter, select your virtual environment kernel:
The kernel should show your venv path, not system Python!
Execute the code cells to start playing:
You're ready to play! Choose positions 1-9 to make your moves.
If the game doesn't run, check that you've selected the correct venv kernel and that all packages are installed in your virtual environment.
