Jetson Nano performance problem
#1
Sad 
Hello,

What is your experience about Nvidia Jetson Nano performance? Do you think it is correct with official data in nvidia datasheet?

We are trying to detect people in video recordings and we can't reach those parameters. We are able to analize video with YOLO Tiny algorithm with only 1 fps.  
We've also tried the same algorithm with Jetson TX2 and it's almost the same result. 

What do you thik about it? Are we not able to set up our script correctly or it can be the Jetson Nano issue?

Do you have any similar expierience in working with those microcomputers? Or mayby do you have some ideas how to improve our results.?

Best regards,
Przemyslaw

Our forum only covers a single home theater software application, Kodi, which plays videos and music files.
I think I can safely say that the number of people on this forum working with Nvidia Jetson boards is very, very close to zero.

There is also entirely no science or A.I. involved in our software for detecting people, animals or other Mother Earth occupants.
I think you took a wrong turn by mistake, and ended up here. Unfortunately, we are not the target audience you are looking for.

It's very old, and very slow. Why wouldn't you just buy a google TPU.

I believe that you must be thinking of the old Nvidia Jetson, and not the new Nvidia Jetson Nano

Nvidia Jetson Nano is a new development board from Nvidia that only cost $99 and at least on paper has the potential to be a great platform for Kodi

Well, yes, it is a new product, but based on the same old technology that the tx1/tx2 are. He is saying the tx1 is old and slow, and sure enough it is. The nano is just a trimmed down version of that. Half the gpu cores.

Don't get me wrong, it is good for what it is. A tiny, relatively cheap computer based on the same platform as the 2015 NVIDIA shield tv box.

I just got one and I am playing around with it. I have mixed feelings.

On the one hand it is the fastest cheap little computer I have ever used, and on the other hand it still petforms like a cheap computer, unable to do serious work.

For streaming etc, I like the Android OS on the Shield better. Just seems smoother than Linux4tegra even though it's the same hardware.

I'm finding it not quite or just barely up to the tasks I had in mind for it.

Worth noting then that the Nvidia Shield TV is widely considered the best Android-based box for Kodi and is also among the best platforms for Kodi if you have a budget under $200(US).

So now that the Nvidia Jetson Nano dev-board only cost $100(US), half of a what an Nvidia Shield TV cost, I don't think it's fair to shoot it down as fast for Kodi, even if it does not come with a remote and case.

For use with only Kodi, the Nvidia Jetson Nano dev-board could be a steal at $100(US) to be used as a 4K HDR capable video player platform, only time will tell.

This is the official Kodi forum, and the only use case we should really discuss for it is as a Kodi media player platform.
