customize Object detect

[ly0303521]

Have I written custom code (as opposed to using a stock example script provided in MediaPipe)

None

OS Platform and Distribution

ubuntu20

MediaPipe Tasks SDK version

0.10.7

Task name (e.g. Image classification, Gesture recognition etc.)

object detection

Programming Language and version (e.g. C++, Python, Java)

C++

Describe the actual behavior

object_detection_desktop_live.pbtxt only work with ssdlite_object_detection.tflite

Describe the expected behaviour

replace ssdlite_object_detection.tflite with other model

Standalone code/steps you may have used to try to get what you need

1. I found in vision tasks, such as object detect only has cpu mode, but in the example of "mediapipe/graphs/object_detection", we can see "object_detection_mobile_cpu.pbtxt" and "object_detection_mobile_gpu.pbtxt", there are both modes, why vision task only has cpu mode. 
2. In object detect task, the parameters of Detect is mediapipe::Image, but in graph "object_detection_mobile_cpu.pbtxt", image type is mediapipe::ImageFrame, How can I convert mediapipe::ImageFrame to mediapipe::Image

The detail is that, I want retrain object detection, than followd https://developers.google.com/mediapipe/solutions/customization/object_detector, there are 4 architectures, so I choose MOBILENET_V2, then I get the model.tflite、model_int8_qat.tflite、model_fp16.tflite, When I replace ssdlite_object_detection.tflite by them in "object_detection_desktop_live.pbtxt", after modifying the parameters of num_classes、num_boxes ... , there is no error, but results of detections are wrong. When I use the code "mediapipe/tasks/cc/vision/object_detector/object_detector_test.cc", the result is right.
MOBILENET_V2
MOBILENET_V2_I320
MOBILENET_MULTI_AVG
MOBILENET_MULTI_AVG_I384

Now, I tried to replace "ssdlite_object_detection.tflite" with EfficientDet-Lite0 (int8), but an error occured, if I want to use EfficientDet-Lite0 (int8), how to set the parameters.

Check failed: raw_box_tensor->dims->data[1] == num_boxes_ (19206 vs. 2034)
