…r PyTorch versions After upgrading PyTorch, the mask array shape became (H, W, 1, 1), which is incompatible with the image array shape (H, W, 3) during broadcasting. This caused the error: "ValueError: operands could not be broadcast together". The fix adds shape validation and adjustment to ensure the mask is always in (H, W, 1) format before blending operations.
