Please, add cmake -DENABLE_REQUIREMENTS_INSTALL=OFF to other build options to disable onnx install and conversion of test models.

We have to fix the behavior, thanks for the report

I can suggest to turn of ONNX frontend using -DENABLE_OV_ONNX_FRONTEND=OFF
It turned out that ONNX is not available for armv7l (see https://pypi.org/project/onnx/1.11.0/#files), while OV build tries to use such module unconditionally.
These 2 errors are because of this: we cannot convert test models from prototxt files to onnx format

[ilya-lavrenov]

Please, provide the actual error message. From the logs we can just see that build fails, but don't see the reason

[YaroslavSchubert]

oh, sorry, let me get back to you with the error message.

[YaroslavSchubert]

I added to arm_cpu_plugin_build.sh script like this

cd $DEV_HOME || fail 12 "OpenVINO build failed. Stopping"

but still got the error.

Please, let me know if I'm doing something wrong.

[ilya-lavrenov]

Please, provide error message.
The original error message should have gone.

[ilya-lavrenov]

UPDATE:
I had a look once again to the issue, since you are using cross-compilation - what is the architecture?
If it's x86_64 I suppose onnx can be installed.

In any case - there is a fix with check for ONNX first before its usage openvinotoolkit/openvino#13069

[YaroslavSchubert]

Yes, it's x86_64.
Thank you.
