The Spaghetti Detective is an open-source project (500+ stars on github) used by hundreds of Jetson Nano fans who are also 3D printing enthusiasts.
Under the hood, The Spaghetti Detective is based on a Convolutional Neural Network architecture called YOLO. It is essentially a super-fast objection-detection model.
The Spaghetti Detective (disclaimer: I’m the developer of this project) was initially created to run on a general-purpose PC for personal use, or Nvidian GPU VMs in the cloud. But more and more users have told me Jetson Nano is a perfect fit for this project. Some users are monitoring 5+ 3D printers at the same time with just 1 Jetson Nano. As a reference, I’m monitoring 10k+ 3D printers for our users with a few GPU VMs in the cloud.
Inspired by the fact that every day there are a few users who asked me about running The Spaghetti Detective on a Jetson Nano, I recently published this guide.
Feel free to ask me any questions about this project.
Edit: An example below. Here are more examples.

I found your project a while back but I got this error: “ERROR: Could not find a version that satisfies the requirement corsheaders (from versions: none)
ERROR: No matching distribution found for corsheaders”. Do you know what was the problem?
Hi @kenneth.jiang ,
Great project , congratulations.
Strange. Not sure I have seen this error before. Can you run the command:
docker-compose exec web bash
pip list
and post the output on the console here?

Oh you need to press the “enter” key after “pip list” command.

Sorry for the delay!
It does look like some python modules are missing from your installation. I’m wondering if you have an older version of the code that happens to be broken.
Is your code up to date with the laste in our github repo? If you are not sure, you follow these instructions to make sure it’s up to date: GitHub - TheSpaghettiDetective/obico-server: Obico is a community-built, open-source smart 3D printing platform used by makers, enthusiasts, and tinkerers around the world.
Let me know how it goes.
