Update train.py

Setting master_port to 1 may cause Permission denied due to failure to bind the port. So it is better to set it to a port greater than 1024.

🌟 Summary

Updated the default master port for Multi-GPU DDP training in the classification training script.

📊 Key Changes

• Changed the master port from 1 to 2022 in the Multi-GPU DDP training command.

🎯 Purpose & Impact

• 🛠️ Purpose: Modifying the master port can resolve potential conflicts with other processes or system services using the old default port.
• 💻 Impact: Users running Multi-GPU Distributed Data Parallel (DDP) training now have a less common default port, reducing the likelihood of port-related issues. This update is specifically helpful for those running multiple training sessions on the same machine/network or dealing with restricted ports.
