The backbones provided within TLT (resnet, mobilenet) - which datasets are they pretrained on?
Do you mean the pretrained models?
See https://ngc.nvidia.com/catalog/models/nvidia:tlt_pretrained_object_detection and
https://ngc.nvidia.com/catalog/models/nvidia:tlt_pretrained_detectnet_v2
It is trained on a subset of the Google OpenImages dataset. Following backbones are supported with these detection networks.
