[Sample][Error] enable Object Detection ... check for missing dependencies when using sl_ai

robotpapier · June 26, 2023, 8:34pm

Hi,
Just received my Zed 2i Camera and installed SDK and CUDA 10.2 on my i5 Nvidia 940mx.
ZED depth viewer, explorer, ZedFu, etc…all works fine

But when compiling sample project with visual studio 2019 C++
I have this error when trying to execute ZED_Body_Tracking_Viewer.exe.
Compilation was successfull but have this message :

[Sample][Error] enable Object Detection  | CORRUPTED SDK INSTALLATION : Corrupted SDK detected. Please reinstall the ZED SDK, or check for missing dependencies when using sl_ai(cuDNN, TensorRT).
Exit program.

I’ve reinstalled the latest Zed SDK 4.0.3.
Same message.

I followed this thread : Problem with object detection : [ZED] [Object Detection] SL_AI_NOT_FOUND
But Dependency Walker is freezing when open sl_ai64.dll

Don’t know what to do

Here are some screeshot when I generated the project in case it can help find the problem :
CMAKE:

CMAKE LOG

RELEASE BUILD EXECUTION ERROR

Can someone help me please?

Ok, it took some time but I have the walker dependency console log:

Error: At least one required implicit or forwarded dependency was not found.
Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.
Error: Modules with different CPU types were found.
Error: A circular dependency was detected.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.

I’ve also attached part of the full result :

Hi,

Depends.exe is quite old and you can use this one instead : GitHub - lucasg/Dependencies: A rewrite of the old legacy software "depends.exe" in C# for Windows devs to troubleshoot dll load dependencies issues.
In my experience, most of the time the missing dll is NvencodeApi64.dll

robotpapier · June 27, 2023, 2:23pm

Hi,
Ok, just analyzed the file with Dependencies, not sure what to look for, it shows no errors.

Where can I get the NvencodeApi64.dll ?

robotpapier · June 27, 2023, 2:30pm

Oh I do have an error, haven’t noticed it :
checksum for sl_zed64.dll is incorrect

besides, I do have NvencodeApi64.dll located in my c:\windows\system32 folder

alassagne · June 27, 2023, 2:59pm

This is quite weird. Can you properly remove 4.0.3, be sure that no dll is still here, then install it again ? in the meantime, it will be 4.0.4 (we released it this morning).

robotpapier · June 28, 2023, 5:12pm

Hi,
I have exactly the same error.

I have uninstalled zed SDK
check no ddl left
reinstall zed sdk 4.0.4
reboot
cleaned the visual studio 2019 project
rebuild the body tracking project in RElease mode x64
execute the exe generated in Release folder
have same error

ZED_Body_Tracking_Viewer.exe
[Sample][Error] enable Object Detection  | CORRUPTED SDK INSTALLATION : Corrupted SDK detected. Please reinstall the ZED SDK, or check for missing dependencies when using sl_ai(cuDNN, TensorRT).
Exit program.

I also Analyzed the new sl_zed64.dll with Dependencies and it show again checksum incorrect same as before.

the build shows no errors but some weird warnings, don’t know if it’s relevant.

I’ve tried to build other projects form the zed sdk samples :

It may be related to the fact that your GPU is very old. What is your nvidia driver ? Can you update it ? Can you run the CUDA samples to check that your CUDA installation does correctly work ?

robotpapier · June 29, 2023, 4:40pm

Hi,
I’ve builded ZED_CUDA_Refocus
it works but not sure what it is supposed to do, clicking onimage to “Refocus” doesn’t do anything…

After that I uninstalled again ZED SDK 4.0.4,
updated nvidia driver which was indeed not up to date since a long time.
I have installed nvidia version 512.15 (512.15-notebook-win10-win11-64bit-international-dch-whql.exe) before I had 441.22

Reinstall ZED SDK

Rebuild ZED_Body_Tracking_Viewer
But have exact same error message :

\ZED_Body_Tracking_Viewer.exe"
[Sample][Error] enable Object Detection  | CORRUPTED SDK INSTALLATION : Corrupted SDK detected. Please reinstall the ZED SDK, or check for missing dependencies when using sl_ai(cuDNN, TensorRT).
Exit program.

In case it is relevant.
When using the included ZED SDK Depth viewer, and selecting Neural for the camera parameters,
it failed.
Neural mode not working

alassagne · June 30, 2023, 8:37am

Your whole AI setup does not work. Neural, body tracking, object detection, etc. I think your CUDA is incomplete in some way. What if you run the dependency program on sl_ai.dll ?

robotpapier · June 30, 2023, 9:53am

As i said, when analyzing sl_ai64.dll
I have checksum uncorrect. See my previous post the screenshot.
Despite reinstalling the sdk

robotpapier · June 30, 2023, 1:10pm

About my CUDA, I have installed 10.2 like you told me

alassagne · June 30, 2023, 3:21pm

Sorry, I’m going in a loop
It can be an error of tensorrt / cudnn. Can you try to install them from nvidia’s website ? TensorRT SDK | NVIDIA Developer and CUDA Deep Neural Network (cuDNN) | NVIDIA Developer

robotpapier · June 30, 2023, 5:30pm

Ok,
Just downloaded

TensorRT 8.4 EA for Windows 10 and CUDA 10.2 ZIP Package
cudnn-windows-x86_64-8.7.0.84_cuda10-archive.zip

But it 's not installation program. Just files insides.
What should I do with them?

robotpapier · June 30, 2023, 5:30pm

besides for tensorflow they have GA or EA version, I picked EA. But don’t know the difference

robotpapier · June 30, 2023, 7:04pm

doesn’t it seems like it can’t locate sl_ai64.dll somehow ?

robotpapier · July 3, 2023, 3:40pm

Hi,
thanks for trying to solve my problem.
But is it possible to continue by email and get faster reply?
I received my Zed 2i 2 weeks ago and still have’nt been able to make it work yet.
It’s really annoying in my project planning for my client
I’m kinda stucked now and need to validate fast (or invalidate) the use of the Zed 2i camera for my game.

robotpapier · July 7, 2023, 7:02am

Hi,
I got a brand new PC

1. windows 11
1. i7 32go RAM
1. NVIDIA RTX 3070 Laptop 8go

Installed latest nvidia driver, CUDA 12.2 and latest ZED SDK

Tried ZED Depth Viewer and selected Mode Neural and have an error message :

Warning
Failed to optimize model. NEURAL mode won't be available.

Please help me solve this fast I have latest hadware now, why is it not still working?

If it is relevant I didn’t installed the Geforce Experience, only drivers.
