Enhanced the error handling in ImageDataset.__getitem__ to prevent potential infinite recursion when loading corrupted or missing image files. The changes include:Added a maximum retry limit based on dataset sizeImproved error messages and loggingBetter separation of file access and image loading errorsMore robust error recovery with proper state managementThis makes the dataset loading more reliable and provides better diagnostics when issues occur.

### Changes- Added proper cleanup of tarfile objects to prevent file descriptor leaks- Improved error handling with more descriptive messages- Added worker safety for multi-process DataLoader scenarios- Enhanced file handling to read and close files immediately### Impact- Prevents resource leaks during training with tar-based datasets- Makes error messages more actionable- Improves stability in multi-worker data loading- Maintains backward compatibility while being more robust
