I have downloaded the models on the page https://ai.google.dev/edge/mediapipe/solutions/vision/object_detector?hl=zh-cn, includes EfficientDet-Lite0 (int8) and SSDMobileNet-V2 (int8) , then I run the android sample object_detection download from https://github.com/google-ai-edge/mediapipe-samples. I can successfully run EfficientDet-Lite0 (int8), but when I run SSDMobileNet-V2 (int8), an error occued.
