I have trained re-trained the SSD-MobileNet-v2 model on my custom dataset with tensorflow-GPU=1.11* and object detection API v1.10*
Im unable to convert the obtained frozen graph to Intermediate Representation (.xml,.bin). The following is the error trace when i run mo_tf.py

'''''''''''''''''''''''''''''''''''
PS:
i) I have appended the start_points in "ssd_support_api_v1.14.json" with "Postprocessor/Cast_1" and yet I receive this error.
ii) I was able to successfully convert the "frozen_graph.pb" file from the SSD-MobileNet-v2 saved model available from the official tensorflow repo. (https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/detection_model_zoo.md)
Is there any particular commit of the object_detection repository on which we should train? I have successfully attempted training on the latest object detection API (2019) with tensorflow 1.15 and 1.11
Both the trained frozen graph prompted the above error message.
Please do suggest a workaround for this error or point me to the particular version/commit of the object_detection API where I could successfully optimize a retrained SSD-MobileNet-v2 model.

Hi Siddharth,
Thanks for reaching out. I see you are trying to convert SSD-MobileNet-V2 model to IR, could you try using the ssd_v2_support.json instead of ssd_v2_support.json and see if that works?
I can also attempt to convert your re-trained model and see if I can find a solution, if possible share your model files so we can try. You can share privately these files in case you don't want to share them publicly.
Regards,
Luis
