Summary
Fix for SAM2 (Segment Anything 2) crashing with KeyError: 'reshaped_input_sizes' / AttributeError
Versions: InvokeAI 6.13.7 and 6.14.1, with transformers 5.5.4.
Cause: Invoke's SAM2 wrapper still passes reshaped_input_sizes to the SAM2 processor. Transformers 5.x removed that field from both the processor output and post_process_masks(), so SAM2 crashes as soon as it tries to read it. SAM1 isn't affected.
Note: The patch only passes the field if it's actually there, so it's safe on older transformers too.
