Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson Orin NX 16 GB)
• DeepStream Version 7.1
• JetPack Version (6.2)

• Issue Type( questions, new requirements, bugs)
I have migrated from Deepstream 6.4 . I cannot locate FacialLandmarks.h. Using deepstream 7.1 and Tao faciallandmarks is possible isn’nt it? i receive from “ds_facialmark_meta.h” build error as

"ds_facialmark_meta.h:28:10: fatal error: cv/faciallandmarks/FacialLandmarks.h: No such file or directory
28 | include “cv/faciallandmarks/FacialLandmarks.h”

Is deepstream_tao_apps/apps/tlt_others/deepstream-faciallandmark-app at release/tlt3.0 · NVIDIA-AI-IOT/deepstream_tao_apps · GitHub compatible with Deepstream 7.1??

Although I integrated tao 5.1 and have installed 7.1 there seems to be no “FacialLandmarks.h” nowhere.

NVAIE (NVIDIA Al Enterprise) release note for DeepStream 7.1, states under “BREAKING CHANGES”: “From DeepStream 7.1, the following models are deprecated. • Facetetect, FacedetectIR, PeopleSegnet, bodyposenet, gesturenet, emotionnet, hearratenet, gazenet, facial landmark estimation models and its corresponding applications.”

Is that true? Will existing applications using the pre-trained facedetect model continue to function without issues in DeepStream 7.1? Is it advisable to incorporate header files from DeepStream 7.0 into a DeepStream 7.1 project to maintain facial landmark detection functionality? Is it advisable to copy include libraries between these versions? Could this lead to compatibility issues or conflicts due to changes in the SDK’s architecture?
Are there recommended alternative models or approaches for facial detection within the DeepStream 7.1 framework?

Thanks

Yes, we have deprecated support for these models from DeepStream 7.1. If you want to implement similar features on this version, you can try to find some open source projects yourself.

4

Can I copy the „deepstream/source/include“ headers from DS 7.0 to DS 7.1 ?
Is there any copyright issues if we continue with these pretrained models commercially?

5

No. We have removed the relevant libs, just copy the header files will not work properly.

6

And would there be any copyright issues if we use it commercially with DS 7.0? As far as I know, DS version 7.0 doesn’t have any recognition limits, does it?

I need to downgrade to JP 6.0 . Is there a jetpack 6.0 sdk downloadable? I cannot login and do with sskmanager as it only can JP 6.1 or 6.2

Thanks for feedback,
Best Regards

As I attached before, we have removed the relevant libs. So you won’t be able to use it properly with the new version. You can try to find some open source projects yourself. It has no recognition limits since it’s your own code implementation.

We don’t recommend you do that because there may be incompatibility issues .

8

Can I install DS 7.0 (and so face recognition libraries of tao) to 6.2 Flashed Jetson Orin NX, or do I have to reflash?

9

We recommend that you install the appropriate version by following the table below Jetson model Platform and OS Compatibility.
