Following the page https://github.com/opencv/opencv/wiki/TensorFlow-Object-Detection-API My step is ：
- train model done.
- run export_inference_graph.py to got frozen_inference_graph.pb
- test to load frozen_inference_graph.pb and predict by tensorflow then got image like this!(make sure pb is ok!)
- run tf_text_graph_faster_rcnn.py to gen graph.pbtxt
- run opencv dnn to load model(done) then to predict a image and the error come out. [org.opencv.core.CvException: cv::Exception: OpenCV(4.1.0) C:\opencv\opencv4.1.0\sources\modules\dnn\src\layers\detection_output_layer.cpp:706: error: (-215:Assertion failed) prior_height > 0 in function 'cv::dnn::DetectionOutputLayerImpl::DecodeBBox' ]
- After that to try the Troubleshooting's methods about optimize_for_inference.py or graph_transforms got same error。
Who can have a similar experience, can guide me, thank you (Once completed ssd_mobilenet_v2_coco by same way)
