In this tutorial we assume to launch a distributed training on 2 nodes using DeepSpeed with the OpenMPI Launcher.

1. First of all DeepSpeed needs a passwordless ssh connection with all the nodes, MASTER included:

# generate a public/private ssh key and make sure to NOT insert a passphrase

ssh-keygen -t rsa

# copy public key 'id_rsa' on the MASTER and SLAVE

I'll help you build a 4x4 tic-tac-toe game in Python with a clean terminal interface. Let me create a comprehensive plan for this project.

Project Plan: 4x4 Tic-Tac-Toe Game

Core Components:

1. Game Board Management

   • 4x4 grid representation using a 2D list

• Clear board display with grid lines and position numbers
