when i load custom model as:
./detectnet-camera --width=640 --height=480 --camera=/dev/video0 --model=/home/fyp/maaz.uff --class_labels=/home/fyp/labels.txt

i received following:

Hi,

[TRT] UffParser: Validator error: ... Unsupported operation _FusedBatchNormV3

Please noticed that FusedBatchNormV3 is not supported in current TensorRT yet.
You can find our supported matrix here:

As mentioned in topic 1071484, please try to serialize the ssd_mobilenetV2 model with a older TensorFlow frameworks and try it again.

Thanks.
