Refactor: Move traceback imports to top of files

[Copilot]

Overview

This PR addresses the code organization issue identified in #1 where the traceback module was being imported inside exception handlers instead of at the top of the file with other imports.

Problem

The traceback module was imported inside exception handlers in two files:

• utils/Trainer.py (2 occurrences in different exception blocks)
• gradio-inference.py (2 occurrences in different exception blocks)

This approach has several drawbacks:

• Violates Python best practices (PEP 8) which recommends placing all imports at the top of the file
• Causes the module to be imported at runtime during exception handling, which is inefficient
• Reduces code readability by hiding dependencies inside exception blocks
• Could potentially import the module multiple times if different exception handlers are triggered

Changes

utils/Trainer.py

• Added import traceback at line 9 with other standard library imports
• Removed duplicate import traceback statements from two exception handlers

gradio-inference.py

• Added import traceback at line 8 with other standard library imports
• Removed duplicate import traceback statements from two exception handlers

All traceback.print_exc() calls remain functional and unchanged.

Benefits

• ✅ Better code organization: Imports are now grouped at the top of the file following Python conventions
• ✅ Improved runtime performance: Module is imported once at load time instead of during exception handling
• ✅ Better visibility: Dependencies are immediately visible when reading the code
• ✅ Minimal changes: Only 2 insertions and 6 deletions across both files

Testing

• ✅ Python syntax validation passed for both files
• ✅ All exception handling functionality preserved
• ✅ No breaking changes to existing behavior

Fixes the code organization concern raised in #1.
