TensorRT not working for custom ssd_mobilenetv2_fn training

[1208overlord]

I have my own trained model with ssd_mobilenet_v2_fn.
And then, I tried both of tensorflow-onnx-trt and tensorflow-uff-trt, but all not working.
In stage of onnx-trt and uff-trt, it gives error.
I am using it on Jetson Xavier now
Can you give me help?

builder.max_batch_size = 1

Parse model file

Hello, I am using this script to convert onnx into trt engine for ssd mobilenet model.
And then, I have the following error.

Beginning ONNX file parsing

f.write(engine.serialize())

What is wrong?
I tried with many articles related to that, but not working.
Could you please give me detailed help directly here?
I appreciate for that.

@1208overlord SSD-MobileNet-v2 is not an MLPerf Edge/Datacenter model. Why are you asking here?
