Use pyserial from inside inference docker

[user79952]

Hello all.

I am trying pass serial data to an arduino, via pyserial, from inside the inference docker but there isn’t any devices in ls dev/ttyusb ?

The pyserial part works outside the docker.

I am running it from inside the inference docker because opencv wont import into python if I try to from outside the docker. I have installed it for sure?

This all works fine on another linux machine, so I just want to pass the usb device to the docker on run ?

Any help would be awesome!

Hi,

Which JetPack do you use?
OpenCV Python is pre-installed via JetPack by default.

To use pyserial inside the container, please check the below topic first:

Connect Jetson nano to Arduino

I have trained my model for object detection, and everything works well, it detects the objects with no problem, however, I would like to connect Arduino to Jetson Nano, so when it detects one of the objects, and the confidence level of the model is above 90% it will send the data to the Arduino and will turn on an LED. I am working with the Jetson-inference library by dusty, cloned from GitHub, however I am finding zero documentation about how to make this sort of things even though I have see…

Thanks.

If you are referring to the jetson-inference docker, try adding flags like --device /dev/ttyUSB0 after this line of the docker/run.sh script:
