Unable to create TRT model from ONNX Opset 5 or higher

I am importing a pertained resnet50 onnx model and running on Jetson TX2. I have Jetpack 4.2 installed on TX2. I am able to import the ONNX file create TRT model, deploy and run inference on TX2 if ONNX model is opset_3. But I get errors if Resnet50 ONNX model is Opset_6 or above. I tried to convert the Opset using the ONNX converter, no luck the conversion to lower Opset itself fails.

https://s3.amazonaws.com/download.onnx/models/opset_6/resnet50.tar.gz (does not work)

I tried to upgrade TensorRT and ONNX with no luck. I thought it is not a good idea to upgrade without using Jetpack.
