Image mode (TensorFlow)

python3 segment-anything-2.py --tflite

Video mode（TensorFlow）

python3 segment-anything-2.py --tflite -v demo

As a constraint, TensorFlow does not support DynamicShape, so the specified point becomes one.

With tensorflow-macos Version: 2.12.0, the ImageEncoder cannot be inferred.
