Build TensorRT Engine killed


I have a Jetson Nano 2gb developer kit
When i try to build a tensorrt engine for yolov3-tiny-416 as in this repro:

Always get the message killed, I have a swap partition created and it has almost no use of it
sudo python3 -m yolov3-tiny-416
Loading the ONNX file…
Adding yolo_layer plugins…
Building an engine. This would take a while…
(Use “–verbose” or “-v” to enable verbose logging.)

This is the use of my memory just before getting killed the process:

free -m
total used free shared buff/cache available
Mem: 1971 1880 34 0 56 24
Swap: 5081 757 4324

I don know how to get it done i have tried
sudo sysctl vm.swappiness=100
sudo sysctl vm.vfs_cache_pressure=200

but it always get killed
Also i tried in the script changing this line:
config.max_workspace_size = 1 << 30 to 29 and it worked but when i try with the dog photo do not see any detection
