Problem with object detection : [ZED] [Object Detection] SL_AI_NOT_FOUND

Software
1

Hi , I am using the ZED 2 Camera with the sdk . I am trying to do the examples about object detection but always have the same error :
[ZED] [Object Detection] SL_AI_NOT_FOUND

Before i had the error that it cant download the model , so i uninstall cuda and zed sdk and installed again the last version of zed sdk with cuda 11.5

I am use windows 10 .

Thank you very much for your help.

Kind regards

Miguel

Hi,

This error means that the ZED SDK cannot load the library that contains object detection (sl_ai.dll)
You can look at the folder C:/ProgramFiles (x86)/ZED SDK/bin/ and check if sl_ai.dll is indeed here.
If yes, use Dependency walker to check if one of the sl_ai dependencies is missing :

  • Download Dependency Walker (https://www.dependencywalker.com/)
  • Open the library file (sl_ai.dll) in DepWalker
  • Check if one of the dependencies is noted as missing.

Hi, I dont have this library but i have the sl_ai64.dll .
I imagine that they are different libraries .

Maybe do i need reinstall ?

No Sorry it’s indeed sl_ai64.dll on windows. What is the result when you open this library with dependency walker?

Hi I attach the image. I can see that in my computer missing some libraries . I think that they are Visual c++ library. but i am not sure that i need to install :thinking:

Hi,

The API-MS…<> is not the problem. They are always appearing like this.
Can you save to a file and post it here?

Probably something else is missing, not visible in your screen capture

Yes , of course.

I send you a we transfer link, because the new user can´t upload file here

Hi,

It seems that you have x86 libraries in your system that conflicts with the x64.
Is you windows 10 in x64 (64bits) ?

Yes, my windows 10 is in x64 . But i always installed the x64 drivers so i am not sure about how change this libraries.

Hi,
I have the exact same error and followed the steps in this thread but could not solve my issue. Did you end up finding the solution?

I actually solved this issue by downgrading to Python 3.8 (I was using the most recent release, Python 3.12) and following the instructions this Github thread.

Glad to hear you’ve solved the issue. Compatibility with Python 3.12 is not yet available and is planned for future releases of the ZED SDK.
