Deepstream6.2 downloading source is unavailabel

Accelerated Computing Intelligent Video Analytics DeepStream SDK

I am working on Jetson Orin NX. The info is listed as below.
Ubuntu 20.04 focal.
Release: 5.10.104-tegra.
Python: 3.8.10
Jetpack: 5.1.1
L4T: 35.3.1
cuda: 11.4.315
TensorRT: 8.5.2.2
VPI: 2.2.7
OpenCV: 4.6.0 with CUDA: YES

Following the vendor’s manual, I need the deepstream6.2 for further study.
At first, I tried the deepstream_sdk_v6.2.0_x86_64.tbz2 package from the vendor, failed with prompt “dlopen error: libnvvpi.so.2: cannot open shared object file: No such file or directory”. I confirmed that, the libnvvpi.so.2 is absent in that package.
Then I try to following the steps from NVIDIA. However, the related downloading links from NVIDIA are unavailable. Both https://developer.nvidia.com/deepstream_sdk_v6.2.0_x86_64.tbz2 and https://developer.nvidia.com/deepstream-6.2_6.2.0-1_amd64.deb are unavailable with prompt “Even AI can’t find this page!”.

I am wondering if anyone could give me some help.

I downloaded the deepstream6.4 pkg and further found that there is not libnvvpi.so.2 in it. So, what’s the magic to get the mystery libnvvpi.so.2?

Please find the archived SDK information here: DeepStream SDK FAQ - #35 by Fiona.Chen.
The installation guide and download link can be found on page Quickstart Guide — DeepStream 6.2 Release documentation (nvidia.com).

Thanks and the links are OK. However, there is still no " libnvvpi.so.2" in the deepstream6.2 package. I am wondering what the libnvvpi.so.2 is and where it comes from.

why are you using x86 package? Orin NX is Jetson device thus you should download deepstream_sdk_v6.2.0_jetson.tbz2 or deepstream-6.2_6.2.0-1_arm64.deb.

How did you check it? libnvvpi2 only exists in Jetson and doesn’t belong to DeepStream.

eh… The x86 package is typo, sorry for that.

I found that the libnvvpi.so.2 comes from the libnvvpi2, instead of Deepstream, just as you said.

The truth is that my libnvvpi2 has been broken, and I have fixed it. Now all the thing is OK.

Many thanks.
