Dear Juj, Satyajith,

Please choose a Resnet50-FPN from this list which have been validated by the OpenVino team. To convert a Tensofrlow Object Detection API model, please follow the steps outlined in the below document:

http://docs.openvinotoolkit.org/latest/_docs_MO_DG_prepare_model_convert_model_tf_specific_Convert_O...

Thanks,

Shubha
