Intel Movidius Myriad X Openvino Version and Support

[jordimale]

Hi!

I've been trying to run different models i had exported on onnx into my Myriad X. After doing all conversions, i get into the error:

Failed on MYRIAD: [ GENERAL_ERROR ]
/home/jenkins/agent/workspace/private-ci/ie/build-linux-ubuntu20/b/repos/openvino/src/plugins/intel_myriad/graph_transformer/src/frontend/frontend.cpp:596 Failed to compile layer "/GridSample": unsupported layer type "GridSample"

These raises multiple questions:
1. Which is the latest Openvino version that has Myriad X support? If not, are future versions going to support it? Im using 2022.3.2, as I read that this seems to be the last with Myriad X support
2. I see GridSample is supported on the Openvino documentation, but clearly my version does not support it.
3. Is there a better approach into running Deep Learning models into Myriad X? If not, what is the best solution on my problem?

Thanks,

Jordi

Hi jordimale,

Thank you for reaching out to us.

For your information, OpenVINO™ 2022.3 LTS will be the last version of OpenVINO™ to support the Myriad plugin. OpenVINO™ 2023 and onwards will not support Myriad plugin.

Referring to the latest OpenVINO™ Operation Specifications, GridSample is supported by OpenVINO™ 2025. To check supported operation on OpenVINO™ plugins, please refer to Section - Device-operation conformance reports in OpenVINO™ Supported Operations.

On another note, you may use the following command to infer your model on several devices:

device = "HETERO:MYRIAD,CPU"

For more information, please refer to OpenVINO™ Heterogeneous Execution.

Wan

Hi Wan,

Understood. This raises a couple of questions, just to confirm.

As you said, GridSample is supported by OpenVINO™ 2025. But, OpenVINO™ 2022.3 LTS will be the last version of OpenVINO™ to support the Myriad plugin. So, if I update to  OpenVINO™ 2025 to use GridSample I cannot run my model on my Miriad X. Is this correct? 

The only option I have while working with Myriad X is to use OpenVINO™ 2022.3 LTS (currently using 2022.3.2), and run either on CPU or using the hetero option you commented. Is this correct?

Thanks again,

Jordi

Hi jordimale,

1. Correct. OpenVINO™ 2025 does not support Myriad X. If you update to OpenVINO™ 2025, you may run the model with GridSample operation on CPU or GPU plugin.
2. Correct. To use Myriad X, the only option is to use OpenVINO™ 2022.3 LTS. For unsupported operation on Myriad X, you may use CPU plugin or use the hetero option as a workaround.

Hope it helps.

Regards,

Wan
