Jul 1, 2025July 2025 at IBM/terratorch focused on robustness, performance, and deployment reliability for segmentation workflows. Implemented segmentation ground-truth tensor squeezing to trim unnecessary dimensions, enabling faster inference and reduced memory usage. Hardened single-sample dataset handling with batch size enforcement, label_grep propagation during prediction, and a fallback mechanism for class discovery to improve reliability across small datasets. Enhanced prediction workflows with optional label in prediction mode and a control flag to create label fields in batches, plus flexible output naming for predictions. Strengthened error handling for pred_batch_ types and addressed CI/dependency stability to reduce build failures and ensure reproducible environments. Fixed device handling for negative values by defaulting to CPU in tiled inference. Minor code quality improvements (typos/spelling) to improve maintainability. Overall, these changes increase predictability, throughput, and reliability of segmentation tasks while reducing maintenance overhead.
