Any beginner tips for Nvidia Jetson?

Hi,

I'm using a Nvidia Jetson board, the 2gb for now moving onto the 4gb later, to track people. I tried setting it up and installing a demo project but ran into lots of errors - a common one was running out of memory and the whole thing freezing on me.

I'm thinking I missed a setup step where I needed to partition the memory??

 

Does anyone know of any setup guides for this board? If it works for what I need to do I might need between 6 and 12 of them! So would like a nice easy setup routine that just works.

 

Thanks!

Lorraine

    If it freezes and it does not unfreeze, you may increase the swap size. https://www.jetsonhacks.com/2019/11/28/jetson-nano-even-more-swap/ and also running headless should help.

    Thanks Allen, yeah I'm guessing the demos are for the 4gb model too! I've got that on order as it was out of stock. I did stick with the default 2gb swap, then had to change it cause it kept freezing.…

    lorrainbow  I just got my own Jetson Nano 2 GB, so I'm a beginner too.  I have not run any of the demos yet, and of course the demos were probably created for the 4GB model.  (but microcenter in the US had the 2GB on sale for $50, couldn't pass that up. )

     

    I downloaded the new operating system "Jetpack 4.5", new version from January 2021.  How much swap do you have? On mine, by default it set swap to 2.5 GB.  You could try setting it higher. Here's an example for a raspberry pi that I have used successfully: https://pimylifeup.com/raspberry-pi-swap-file/

     

    I do have to say, the jetson nano 2Gb is fast, faster than my Pi 4.

    Sorry, bad answer about swap.  That Pi link definitely did NOT work.  (note to self: don't assume raspbian is the same as debian )

     

    The nano is running ubuntu 18.04, I'm going to try this next:
