Describe the problem

I'm trying to customize the model type for `/mediapipe/tree/master/mediapipe/examples/ios/posetrackinggpu` example. If I understand correctly, posetrackinggpu supports 3 models: `pose_landmark_full`, `pose_landmark_heavy`, and `pose_landmark_lite`. I did attempt to change `//mediapipe/modules/pose_landmark:pose_landmark_full.tflite` to `//mediapipe/modules/pose_landmark:pose_landmark_heavy.tflite` or `//mediapipe/modules/pose_landmark:pose_landmark_light.tflite` in posetrackinggpu BUILD file as well as changing `model_complexity` to 0 or 2 in `mediapipe/python/solutsions/base.py` and recompiling with Basel. Changes seem to break pipeline, running app with new changes logs following error in the console: 

::Open() for node "poselandmarkgpu__poselandmarkbyroigpu__poselandmarkmodelloader__LocalFileContentsCalculator" failed: ; Can't find file: mediapipe/modules/pose_landmark/pose_landmark_full.tflite, GUSGoogleUtilStatusErrorKey=<GUSUtilStatusWrapper: 0x2835e80e0; status = Graph has errors:
