HI Nvidia forum,

I am on Orin developer kit and jetpack 5.0. I have finished the setup process and finished install jetpack, but there is no nsight compute come with jetpack

in /opt/nvidia, here is what I have:

Could you please help me install the correct version of ncu? Thank you!

Are you asking for Orin or Orin NX?
Could you move to the last test JetPAck 5.1.2 SW?

Hi,

Please try the following command:

$ sudo apt install nsight-compute-2022.2.1

Thanks

Hi Kayccc,

sorry for the delayed reply, I believe it should be orin, and do you know how to double check my current jetpack version?

$ cat /etc/nv_tegra_release

Hi AastaLLL,

I tried this before on another jetson module, but seems not working… anyway I will try it on orin

Thanks,

I found the ticket when I tried this before lol No kernel to profile when using nsight compute - #8 by czxu

Is this still an issue to support? Any result can be shared? Thanks

Hi kayccc,

I found the ncu and ncu-ui exe file via your answer in another post (thank you!) and tried to profile a kernel

the strange thing is that I got a ncu-rep file, but seems that ncu-ui can only open ncu-proj file and does not allow me to select the ncu-rep file… do you know how I could correctly read the ncu-rep?

Thank you so much!

Best,
Chengzhe

hmmmm I remember that I came across the same issue before when working on a normal linux station (x86), and the solution at that time is to use a newer version of nsight compute, I am wondering do we have some newer version for jetson platform?

Hi,

Please note that only cli profiler can work on the Jetson.
Did you try to open the file on an x86 desktop?

The Nsight Compute Profiler file can be opened as following:

File → open File → *.ncu-rep

Thanks.

hmmm on my mac it only allows *.nsight-cuproj, *.nci-proj… Do you know which version of the nsight compute should I install?
Thank you!

Hi,

We use 2022.2 on the Ubuntu desktop.
The tool is installed through the SDK manager.

Thanks.

Thank you AastaLLL,
Sorry for the delayed reply (I am kinda occupied those days…) I will try the 2022.2 version!
Best,
