• How to reproduce the issue? (This is for errors. Please share the command line and the detailed log here.).
Hi all, I need to retrain the object detector RetinaNet with several backbones (Resnet50, Efficientnet_b1_relu, Mobilenet_V2, etc). I am using the pre-trained models from TAO Toolkit SDK and well as the reference TAO Jupyter Notebook and training specs for ResNet-18 RetinaNet model on the KITTI dataset. Where can I find the below equivalent training configuration files for the pre-trained models Resnet50, Efficientnet_b1_relu, Mobilenet_V2?

Please modify below in the training spec file.
For example, for resnet 50, please set

arch: “resnet”
nlayers: 50
