PR Review: Revert "Update model loading and add new features"

I've reviewed this revert PR and analyzed the changes being undone. Here's my comprehensive feedback:

Todo List

• Read and analyze changed files (.gitignore, geort/dataset.py, geort/export.py)
• Understand what functionality is being reverted
• Check if the revert is clean and complete
• Analyze potential issues or dependencies
• Provide comprehensive review feedback

Changes Being Reverted

This PR reverts functionality that was added in PR #2, specifically:

.gitignore Changes

• Reverted: Removes ignore patterns for checkpoint/* and data/* directories
• Impact: These directories will now be tracked by git again

geort/dataset.py Changes

• Reverted: Un-comments a print statement at line 50
• Change: # print("Keypoint Names", self.keypoint_names) → print("Keypoint Names", self.keypoint_names)

geort/export.py Changes (Most Significant)

• Reverted: Enhanced model loading functionality
• Removed: import json
• Reverted: Function signature change load_model(tag='', epoch=0, use_best=True) → load_model(tag='', epoch=0)
• Removed: Logic to preferentially load best.pth over last.pth
• Removed: Training history display when loading best models
• Reverted: Print statement uncommented

Review Feedback

✅ Code Quality & Best Practices

• The revert is clean and well-executed
• All changes appear to be properly reverted to the previous state
• No leftover artifacts or incomplete removals detected
• Function signatures are properly restored

⚠️ Potential Issues

1. Breaking Changes: The load_model() function signature change removes the use_best parameter

   • Impact: Any external code calling load_model(tag="foo", use_best=True) will now fail
   • Recommendation: Check for any dependent code that might be using this parameter

2. Model Loading Behavior Change:

   • Before revert: Could load best performing model (best.pth) with training metrics
   • After revert: Only loads latest model (last.pth)
   • Impact: Users may unknowingly get different (potentially worse) model performance

3. Gitignore Impact:

   • Risk: checkpoint/ and data/ directories might now be accidentally committed
   • File size concern: These directories likely contain large model files and datasets
   • Recommendation: Ensure these directories are empty or use .gitkeep files

📊 Performance Considerations

• Positive: Simplified model loading logic should be slightly faster
• Negative: Loss of best model selection may impact inference quality
• Verbose Output: Re-enabled print statements will increase console output

🔒 Security Concerns

• Low Risk: No security vulnerabilities introduced by this revert
• Data Exposure: Removing gitignore entries could potentially expose model checkpoints if they contain sensitive data

🧪 Test Coverage

• Unknown: Cannot assess test impact without seeing test files
• Recommendation: Verify that tests expecting the use_best parameter are updated or removed

Overall Assessment

This is a clean technical revert with proper implementation. However, the removal of enhanced model loading features represents a functional regression that may impact users who depended on:

• Loading best-performing models automatically
• Training history visibility
• The use_best parameter in the API

Recommendations

1. Update Documentation: If this revert is intentional, update any docs referencing the removed features
2. Check Dependencies: Search codebase for any calls to load_model(use_best=True)
3. Consider Staged Approach: If the enhanced features had issues, consider fixing rather than complete removal
4. Monitor Model Performance: Users should be notified that model loading behavior has changed

The revert itself is technically sound, but consider whether this represents the desired long-term state or if this is a temporary rollback while issues are resolved.
