Open Images Pre-trained Object Detection
Object detection is a popular computer vision technique that can detect one or multiple objects in a frame. Object detection will recognize the individual objects in an image and places bounding boxes around the object. This model object contains pretrained weights that may be used as a starting point with the following object detection networks in TAO Toolkit to facilitate transfer learning.
YOLOv3
YOLOv4
YOLOv4-tiny
FasterRCNN
SSD
DSSD
RetinaNet
It is trained on a subset of the Google OpenImages dataset.
The following backbones are supported with these detection networks:
resnet10/resnet18/resnet34/resnet50/resnet101
vgg16/vgg19
googlenet
mobilenet_v1/mobilenet_v2
squeezenet
darknet19/darknet53
efficientnet_b0
cspdarknet19/cspdarknet53
cspdarknet_tiny
Some combinations might not be supported. See the matrix below for all supported combinations.

These are unpruned models with just the feature extractor weights, and may not be used without retraining to deploy in a classification application.
Please make sure to set the
all_projectionsfield toFalsein the spec file when training a ResNet101 model.
