🌟 Summary

📊 Key Changes

• 📦 Added pkg_resources (as pkg) for version checking.

• 🔒 Improves overall stability with a more controlled wandb login flow.
• 🛠 Users will experience more reliable wandb integrations, especially in distributed training scenarios.
• ⏱ Adds a timeout to wandb login for better failure handling.
