🌟 Summary

Replaces pkg_resources version checks with packaging.version.parse for Weights & Biases (W&B) login gating in YOLOv5 logging 🔧📈

📊 Key Changes

• Swapped import pkg_resources as pkg ➜ from packaging.version import parse
• Updated the W&B version comparison logic to use parse(wandb.__version__) >= parse("0.12.2")
• Kept existing behavior: only attempts wandb.login() when running on primary ranks (RANK in {0, -1}) 🚦

🎯 Purpose & Impact

• Reduces reliance on pkg_resources (often considered heavier and increasingly discouraged) ➜ cleaner dependency usage 🧹
• Improves compatibility and reliability of version parsing/comparisons for W&B 🧩
• Minimal user-facing change: logging behavior should remain the same, but environments without pkg_resources quirks are less likely to hit import/version issues ✅

PR looks clean. The switch to packaging.version.parse appears behavior-neutral and no issues are evident in this diff.

Merged — huge thanks for the thoughtful improvement here, @Y-T-G! 🙌

As Leonardo da Vinci said, “Simplicity is the ultimate sophistication.” This PR is a perfect example: swapping out the heavier pkg_resources approach for packaging.version.parse keeps YOLOv5’s W&B login gating cleaner, more reliable across environments, and easier to maintain—while preserving the exact rank-safe behavior (RANK in {0, -1}).

Really appreciate you taking the time to refine the details that make the whole project smoother for everyone. 🚀
