Jetson Nano Jetpack 4.4

Describe the bug I was trying to test the detection algorithm on my Jetson Nano, I followed the instructions for building the container.

To Reproduce Steps to reproduce the behavior:

1. I built the container as stated in the repo:

sudo docker build -f jetson-nano.Dockerfile -t "neuralet/jetson-nano:applications-smart-distancing" .

1. When I run I get the following error:

sudo docker run -it --runtime nvidia --privileged -p 8000:8000 -v /srv/demo/neuralet:/repo neuralet/jetson-nano:applications-smart-distancing

Traceback (most recent call last): File "neuralet-distancing.py", line 22, in <module> DistanceApp(args) File "neuralet-distancing.py", line 13, in __init__ self.engine = CvEngine(self.config) File "/repo/applications/smart-distancing/libs/core.py", line 23, in __init__ self.detector = Detector(self.config) File "/repo/applications/smart-distancing/libs/detectors/jetson/detector.py", line 17, in __init__ from . import mobilenet_ssd_v2 File "/repo/applications/smart-distancing/libs/detectors/jetson/mobilenet_ssd_v2.py", line 3, in <module> import tensorrt as trt File "/usr/local/lib/python3.6/dist-packages/tensorrt/__init__.py", line 1, in <module> from .tensorrt import * ImportError: libnvinfer.so.6: cannot open shared object file: No such file or directory

I assume this is inside the docker container the missing library because I do not have this problem on the Jetson nano itself.

Any help would be appreciated.

Thank you

This branch runs on 4.4, @svetlanadataper https://github.com/mdegans/smart-social-distancing/tree/gst-merge

Just waiting for a code review so it can be merged into master. No guarantees it will be accepted since the way it works differs from the other branches, but it is something you can use right now. Check out the readme in that repo for instructions on building/running.

I downgraded my Jetson Nano to JetPack 4.3 and worked fine. Thanks!
