Hello,
I have been trying for several weeks to run the Getting Started Object Detection demo from the STM32 GitHub repository.
I followed both the GitHub and all the steps from the official guide:
“How to run AI models from model zoo on STM32N6” by @B.Montanari (ST Employee)— but the STM32CubeIDE part does not work for me.
Each time I try to open the Debug Configuration or start the debugger, I get the following error:
An error has occurred. See error log for more details.
Range [0, -1] out of bounds for length 44
I saw that @Ghofrane GSOURI (ST Employee) suggested removing this line from the .project file:
<nature>com.st.stm32cube.ide.mcu.MCUAppSProjectNature</natureAfter doing that, I can open the Debug Configuration and start debugging,
but when I upload the project to my STM32N6570-DK board, the demo doesn’t run properly(black screen or the ia doesn't work).
Here is what I have already tried:
Following the full official STM32 AI / Model Zoo setup guide step by step
Using different STM32CubeIDE versions (1.17.0, 1.19.0 etc.)
Testing multiple AI models
Reimporting and rebuilding the project
Switching workspaces and reinstalling the IDE,.metadata deleting,
Unfortunately, the issue persists — I can’t successfully debug or run any of the models.
Since I’m currently working on a school project, I really need to get this demo running to continue my work.
Could someone from ST or the community please help me solve this problem?
Thank you very much for your support.
Best regards, xoxo
Abdalla

Hi @Goat_abdalla,
I tried your object_detection_all_project and successfully ran it.
I had to delete the /debug, build the project and then delete the debug configuration.
I never encountered the range error.
Please try what I did, we never know, else, is it possible for you to uninstall any cubeIDE on your pc and then reinstall the version 1.18.1 (prior to 1.19.0) and see if it helps?
If it doesn't, please create a thread on the tools forum board as this seems to be purely a cubeIDE issue...
Let me know what results your tests give.
Have a good day,
Julian

Hi @Goat_abdalla,
The Range error should be only present in 1.19.0. In your screenshot you are using this version, but it seems that you also get this error on other CubeIDE versions? (It would be strange)
When using model zoo, make sure to use the yaml file in the same folder as the model (and edit it to deploy the model) Could you please share the logs you get?
Could you please try to deploy this one:stm32ai-modelzoo/object_detection/st_yolo_x/ST_pretrainedmodel_custom_dataset/st_person/st_yolo_x_nano_480 at main · STMicroelectronics/stm32ai-modelzoo
using the yaml alongside the model.
Make sure to install the model zoo services in a virtual env as explain in the main readme.
Have a good day,
Julian

Hello, julian
Thank you so much for your help.
I confirm that I'm using the YAML file in the same folder as the model as recommended.
However, I still get the same "Range [0, -1) out of bounds" error.
I have also tested with STM32CubeIDE version 1.17.0, and I still encounter the same problem.

Hello @Goat_abdalla,
I am not sure to understand, in all your screens, you seem to use cubeIDE 1.19.0.
Really, this range error was only observed in 1.19.0.
In your yaml, you have this:
tools:
stedgeai:
version: 10.2.0
optimization: balanced
on_cloud: False
path_to_stedgeai: C:/Users/@/STM32Cube/Repository/Packs/STMicroelectronics/X-CUBE-AI/10.2.0/Utilities/windows/stedgeai.exe
path_to_cubeIDE: C:/ST/STM32CubeIDE_1.19.0/STM32CubeIDE/stm32cubeide.exe
Which also suggest that you use the 1.19.0.
Have a good day,
Julian

Hi,julian I tried with version 17. I managed to unlock the debug option, but after the second “Next”, I ran into an error.
have a good day,
2025-10-21 5:31 AM
Hi @Goat_abdalla,
You are using the version 1.19 on windows and 1.17 on mac? Is that right?
We do not guarantee the support on mac for model zoo, I believe, this could cause some issue...
Could you try on a not version 1.19 on windows please? And attach your generated project in a .zip if you still have an issue please?
Have a good day,
Julian
2025-10-22 12:38 PM
Hi Julian, thank you so much for your support
I just tried again with version 17 on my Windows PC, but I’m still getting the same errors. I can’t even start debugging I can’t get into debug mode at all, it’s still showing the same error (44, etc.)
I’m really grateful for your help Julian, thank you.

Hi Julian,
I managed to upload my code on my Windows without any errors! I uninstall all IDE and try
I used the IDE version 1.18, and it works perfectly.
Thank you so much for all your support and follow-up, i really appreciate it.
Wish you all the best and continued success!
Best regards,
Abdalla
