Cannot deserialize plugin BatchTilePlugin_TRT

Hi,
I have trained my model on transfer learning toolkit (Meat arch - ssd, Model- Resnet-18). but when I am using engine file in Deepstream test-2 application I am getting error like

Segmentation fault (core dumped)

With meta-arch detectnet_v2 resnet18 it was working fine but with ssd resnet18 getting error .

Please help.

Hi solanki,
SSD requires batchTilePlugin.
Please see below for more info.
