Optimization with TensorRT optimization Tool of MobileNET_SSD with PriorBox Layer.

I am trying to use the TensorRT optimization tool with Driveworks 1.12 for optimizing MobileNET_SSD caffemodel. Is the PRIOR_box layer a custom plugin layer and hence not compatible?

I get This error.Message type “ditcaffe.LayerParameter” has no field named “prior_box_param”

Dear a.a.menezes,
The last DRIVE SW release for DRIVE PX2 does not support plugin layers in DW. Note that we are targeting our DRIVE SW releases for DRIVE AGX platform. Please consider upgrading to DRIVE AGX to get latest SW releases.
