Segmentation Fault when Running Inference on Voyager SDK 1.5.1 (Metis PCIe Card)

Question

Hi,I installed Voyager SDK 1.5.1 on Ubuntu 22.04 and the Metis PCIe card is detected correctly, but running inference results in a segmentation fault.System Setup	OS: Ubuntu 22.04 (AMD64)			Hardware: Axelera Metis PCIe card			SDK Version: Voyager SDK 1.5.1			GPU/CPU: AMD Ryzen + integrated GPU			Installation completed successfully:	No pending installation tasks. To activate the environment, type: source venv/bin/activate PCIe Card Detectionlspci -tv correctly shows the Metis device:+-01.1-[10]----00.0 Axelera AI Metis AIPU (rev 02) IssueWhen I run a sample inference:./inference.py yolov5s-v7-coco media/traffic1_1080p.mp4 --verbose I get:WARNING: Failed to get OpenCL platforms : clGetPlatformIDs failed: PLATFORM_NOT_FOUND_KHR Segmentation fault (core dumped) The last debug messages:DEBUG: Setting state of pipeline0 to GST_STATE_READY DEBUG: pipeline0: state-changed (null to ready) Segmentation fault (core dumped) What I’ve checked	SDK installation is complete			PCIe card detected			Firmware + drivers installed (metis-dkms == 1.4.4, axelera-multi-device == 1.0.0)			Activated virtual environment			Media file loads (GStreamer detects FPS correctly)	Questions	Why does the GStreamer pipeline trigger a segmentation fault?			Do the OpenCL warnings indicate a missing GPU runtime that the SDK requires?	Any help or suggestions would be greatly appreciated!

Hi guys, sorry to hear you’ve hit a couple of problems with 1.5.1.

Before we dig too deep, did you recompile any models that were compiled with a previous version of Voyager? There’s a breaking change in 1.5 that requires models to be recompiled, or redownloaded if it’s a pre-compiled model from the zoo.

Bit of a pain admittedly, but in the long run this change will really yield fruit! 😀
