Help with Neural Network Optimization Issue

Software

Hi, I’m having an issue with optimizing my neural network. It doesn’t proceed at all, whether I try from the diagnostic application or directly from the command line, even after cleaning the models. When trying to optimize from the command line after downloading the model, it starts optimizing at 0.1% as shown in the image, but then it stops. I’ve tried using the latest SDK 4.25 and 4.1 with CUDA 12 and 11.8, and I’ve fully uninstalled and restarted everything.

I have 5080 and Ultra 9 285K

Hi @MechatronicMan
with RTX GPU cards we recommend using CUDA 12.
Please uninstall CUDA 11.8, verify that you installed the latest version of the GPU driver, and then install CUDA 12.6.
Then uninstall the ZED SDK and reboot.
Finally, install the ZED SDK v4.2.5 and verify with ZED Depth Viewer that you can correctly optimize the NEURAL Depth model.

sorry but still the same

all done with full reboot after each step.

Hi @MechatronicMan
we are investigating a possible compatibility issue with the RTX GPU models of the series 5000.

Meanwhile, to exclude an eventual bad configuration, can you test if you can build and run one of the CUDA samples?

Hi, I have problems with visual studio (camke generate files correct) but not specialist in and have problems with other librarys also… But i have other test on the same machine with win10 zed sdk 4.25 and cuda 12.6 also the same error

maybe it will help, it’s look that zed appear in GPU mem from cuda point of view

Hi,
Thanks. We may have found the problem. Would you be interested in testing an installer which could fix the issue? Unfortunately, I can’t test it on real hardware. Here’s the link for Windows CUDA 12: https://stereolabs.sfo2.cdn.digitaloceanspaces.com/zedsdk/4.2/ZED_SDK_Windows_cuda12.1_v4.2.6.exe
Let us know if this solves it.

start testing will let You know :slight_smile:

So test on 12.1, 12.6, 12.8 with full cycle of restart and still error in diagnostic tool, in command line still error but get 0.5% of progress :stuck_out_tongue:

After investigating and for future readers, the ZED SDK 4.2 doesn’t support Blackwell GPUs. We’re working on supporting it in a new release (it will require TRT 10 and CUDA 12.8)
