I use ssd_mobilenet_v1_coco model with OpenCV for object detection.
cvNet = cv.dnn.readNetFromTensorflow('frozen_inference_graph.pb', 'graph.pbtxt')
When using original graph.pbtxt it is OK. But when i create pbtxt file using tf_text_graph_ssd https://github.com/opencv/opencv/blob/master/samples/dnn/tf_text_graph_ssd.py
python tf_text_graph_ssd.py --input frozen_inference_graph.pb --output pbtxt/frozen_inference_graph.pbtxt
and then:
cvNet = cv.dnn.readNetFromTensorflow('frozen_inference_graph.pb', 'pbtxt/frozen_inference_graph.pbtxt')
it gives error:
OpenCV Error: Unspecified error (Input layer not found:
FeatureExtractor/MobilenetV1/zeros) in

namespace'::TFImporter::populateNet, file C:

What is the problem when converting pb to pbtxt?
Here my aim is create custom model using image retraining and use it on OpenCV. https://www.tensorflow.org/tutorials/image_retraining
So I have a custom model but not pbtxt file.
First i try to create pbtxt for an example ssd_mobilenet_v1_coco model.
