Current version change to 3.6 Object detect issue #436
Comments
I am also facing the same issue with the newer version of SDK, cuda version Iam using is 10.2. Check the below message:
|
Could you try to uninstall CUDA then completely remove the CUDA folder and reinstall it ? I suspect it's a conflict of version with TensorRT and/or cuDNN installed by 3.5. |
Apparently there is a problem with cuDNN. I just tried installing cuda toolkit several times but it didn't solve the problem. |
The 3.6 is currently using cuDNN 8.2 (3.6.0 installs 8.2.1). Installing it separately is not something we recommend to avoid issues. |
I also have no experience with separately installing cunn while using zed. But I checked the current cuda toolkit folder, Another question is, is there any difference in object detection performance between cuda 10 version and 11? |
Ok we'll investigate this issue, cuDNN should be installed with cuda 11. We didn't notice any major performance differences between cuda 10.2 and 11 for the object detection. |
I just reinstalled and checked. Even in the cudnn 8.x version of the manual, it is recommended to copy the .dll file to the cuda11 related folder when installing windows. My computer may be the problem, but please review. |
I am currently using Cuda-10.2 and CUDNN 7.6.5, do SDK 3.6 doesn't work this version of cuda and cudnn?, do I have to install cuda-11 and cuDNN 8.2 to work with SDK 3.6 ? |
@hagsac There seems to be an issue, you should indeed have the cudnn files in the cuda 11 folder. We'll do some testing to try to reproduce this. @harishkool If you need specifically cudnn 7.6.5 for other libraries then no, you should not upgrade. 3.6 is compatible with cuda 10.2 and 11.x and installs it's the required version of cudnn and tensorrt automatically. |
@hagsac I checked and on Windows we install cudnn and tensorrt in the ZED SDK installation folder. |
Thanks for your help. In fact, this problem existed in version 3.5.x.Due to some of my actions, it became a normal operation, and although it has been used so far, an error occurred in the sdk check of the actual [zed 3.5.x Diagnostic app]. And I found a hardware problem that occurs in zed2, zed2i that I learned a few months ago, where should I submit this problem? |
@hagsac regarding the hardware problem please write an email to support@stereolabs.com |
@Myzhar @adujardin I have uninstalled cuda-10.2 and installed cuda-11.3 and cudnn-8.2, I am still facing this issue.

Ok, so it's not about the version of CUDA then.
First clean all remaining model related files:
Then try to optimize them:
|
@hagsac The 3.6.1 has been released and should fix your issue with CUDA 11.4, if it doesn't please follow the procedure above, thank you |
I don't understand, I have installed cuda-10.2 again and tried the newer SDK 3.6.1 released, I am not facing segmentation faults now. Will work more with the object detection API and get back to you If I face any issues. |
Hello i have the same issue, i am using ubuntu 18.04 with cuda 10.2 and ZED sdk 3.7.0 GPU RTX 2080 with 12GBobject detection example causes segmentation fault.-> here is a result /usr/local/zed/tools/ZED_Diagnostic -aio Optimizing all AI models Running ldd /usr/local/zed/sl_ai.so shows: |

Preliminary Checks
Description
In the previous CUDA 11.1, 3.5.X SDK is normally used,
After installing CUDA 11.4, and 3.6 SDK,
There is a problem in the dialog history of the ZED SDK and Graphics Card.
After changing to CUDA 10.2 and installing 3.6SDK, the dialog is normal as shown in the figure below, but Object Detect does not work properly.
Steps to Reproduce
Expected Result
Normal operation.
Actual Result
ZED Camera model
ZED2i
Environment
win 10 Processor Intel(R) Core(TM) i7-8700 CPU @ 3.20 GHz 3.19 GHz 16.0 GB of installed RAM System type 64-bit operating system, x64-based processor rtx 2070 1.cuda 11.4 sdk 3.6, 2.cuda 11.2 sdk 3.6
