Show HN: Offline Object Detection and Tracking on a Raspberry Pi

[dividuum]

Is there a more self-contained way of running trained models on devices like the Pi? Almost all tutorials I've come across always require me to install a lot of Python dependencies. I'd love to have classifiers installed as a single binary somewhere. I guess https://pjreddie.com/darknet/yolo/ is pretty close to that and I would imagine with a custom build wrapper around https://github.com/tensorflow/tensorflow/tree/master/tensorf..., the same could be achieved. Any hints?

Not exactly a single binary, but Flogo - https://github.com/TIBCOSoftware/flogo uses one binary + one .so for TF inferencing. See https://tibcosoftware.github.io/flogo/development/flows/tens... for some basic documentation.

We’re looking to grow this further with a model serving service so that its more controlled and better abstracted from processing logic - A/B, champion/challenger, etc. Core devs hang out on gitter in case you have qns or feedback.

This has a way to do it without installing anything https://medium.com/nanonets/how-to-easily-detect-objects-wit...

You could use tensorflow.js, not self-contained, but it only depends on the browser. And... Is it easy to get openCL working on a Pi? WebGL might be slower, but it ought to just work.

You want to proceed carefully with a Pi Zero - the chip is an ARMv6, so you'll end up building more things and you loose some optimization - you might not like the performance :-(

Why not just install all the python 3 dependencies to a docker image and then run the docker container on the pi?

This was actually my original approach. I meant to mention that. And I got it to work but then I had to figure out how to control the hardware from the pi and I just gave up. To be fair, I didn't try too hard. I'm sure there is a way to communicate with peripherals through

Since the Pi is ARM, you'd need to get pip to cross-compile any native extensions in the Python libraries (or use a pre-compiled wheel, if available).

Why python and not c++?
