Before using openvino to inference, following python code is called in plugins to judge whether openvino supported devices (CPU, GPU, GNA .etc) are existing. This code succeeded to run in previous windows version, but it failed to run in current windows version [Version 21H2(OS Build 19044.2006) with latest windows update]. It crashes inside GNA.dll. We doubt the reason is that GNA driver is updated following with windows update while we have no way to confirm it. Our using openvino version is 2020.3.2 LTS. Due to some reason, it is hard to update this openvino version to latest.
Does anyone know the reason?
if len(self.ie.available_devices) == 0:
raise RuntimeError("Cannot init OpenVINO.")

Hi longfei98,
Yes, you’re right. Intel® Gaussian & Neural Accelerator (Intel® GNA) driver for Windows is available through Windows Update.
For your information, Intel® GNA for Intel® Distribution of OpenVINO™ Toolkit 2020 is only supported by Windows 10, 64-bit.

Hi Peh:
Thank you very much for your reply.
Current we have been testing in windows 10, 64bit OS. The crashing happens in that OS.
Do you have any idea about it? Much appreciate.

Hi longfei98,
Could you share your hardware details (GNA driver version and Intel Processor model) with us?
If possible, please have a quick test with the latest OpenVINO version by downloading from PyPI.
Regards,
Peh
