Tensorflow' Pb And Pbtxt Files Don't Work With Opencv After Retraining Mobilenet Ssd V1 Coco

I have followed this tutorial to retrain MobileNet SSD V1 using Tensorflow GPU as described and got 0.5 loss after training using GPU (below more info about config) and got model.c

Solution 1:

The error was caused by the wrong input .pbtxt file passed into the function readNetFromTensorflow because the .pbtxt has to be geneated by tf_text_graph_ssd.py as describe here:

Run this script to get a text graph of SSD model from TensorFlow Object Detection API. Then pass it with .pb file to cv::dnn::readNetFromTensorflow function.

For other models such as faster r-cnn and mask r-cnn, there are also corresponding scripts.

PS: I just found there is a very good official tutorial here.
