- Fixed authentication error when loading V2 models by adding non-auth direct URLs - Added multi-URL fallback downloading system for better reliability - Fixed tensor dimensionality mismatch in MiDaS model interpolation - Added tensor shape standardization to ensure consistent dimensions - Enhanced model directory detection to support multiple folder structures - Improved error messages with targeted solutions based on error type - Added tensor type validation to prevent DoubleTensor vs FloatTensor issues
