Problem loading tensorflow ssd model for openvino on a raspberry

[FSern]

Hello,

I want to run the ssd_mobilenet from tensorflow models api on a raspberry with movidius using openvino but I have problems loading the IR file.

I installed the lastest version of openvino on my pc (ubuntu 16) following this guide https://docs.openvinotoolkit.org/latest/_docs_install_guides_installing_openvino_linux.html

then I used the model optimizer to create the IR file and tested it no problem.

then I installed openvino for raspbian following this guide https://docs.openvinotoolkit.org/latest/_docs_install_guides_installing_openvino_raspbian.html

but, while running the sample I got an error

RuntimeError: Check 'axis < static_cast<size_t>(input_rank)' failed at /teamcity/work/scoring_engine_build/releases_2020_1/ngraph/src/ngraph/op/gather.cpp:140:

While validating node 'Gather[Gather_1718](patternLabel_1714: float{10,20,30}, patternLabel_1715: int64_t{5}, patternLabel_1717: int64_t{1}) -> (??)':

The axis must => 0 and <= input_rank (axis: 4294967295)

and I found that this guy had the same problem https://software.intel.com/en-us/forums/intel-distribution-of-openvino-toolkit/topic/848966

using the model form 2019 to run the sample worked perfectly but I still get the error when I try to use my bin and xml

Hi FSern,

Thanks for reaching out.

As you can check on the thread you referred to, this is an issue with the latest OpenVINO™ toolkit version (2020.1). The "axis" error is caused by the new IR v10 format.

Could you please generate the model with the following parameter and tell us if it works: 

--generate_deprecated_IR_V7

If it does not work, we recommend you installing the previous version of OpenVINO™ toolkit (2019 R3.1) on your Ubuntu 16 system, convert the model there, which will generate the IR v7 format and that should work successfully with the Intel® Neural Compute Stick 2 on the raspberry pi.

Please, as this post is a duplicate from this thread, reply to us on that forum and we will continue to give you assistance there.

Best Regards,

David C.
