myriad_compile - dyld: Library not loaded: @rpath/libtbb.dylib? on Mac OSX 10.15.7 + 2021.2

Ray_Lo_Intel · ‎01-22-2021

Is there a way to work around this issue in Mac? It seems the libtbb was not loaded properly?

dyld: Library not loaded: @rpath/libtbb.dylib

  Referenced from: /opt/intel//openvino_2021.2.185/deployment_tools/inference_engine/lib/intel64/myriad_compile

  Reason: image not found

I check and the setupvars.sh is executed properly, and all these variables are set.

source /opt/intel/openvino_2021/bin/setupvars.sh

 if [[ "$OSTYPE" == "darwin"* ]]; then
        export DYLD_LIBRARY_PATH=$INSTALLDIR/deployment_tools/inference_engine/external/mkltiny_mac/lib:$INSTALLDIR/deployment_tools/inference_engine/external/tbb/lib:${IE_PLUGINS_PATH}${DYLD_LIBRARY_PATH:+:DYLD_LIBRARY_PATH}
        export LD_LIBRARY_PATH=$INSTALLDIR/deployment_tools/inference_engine/external/mkltiny_mac/lib:$INSTALLDIR/deployment_tools/inference_engine/external/tbb/lib:${IE_PLUGINS_PATH}${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}
    else
        export LD_LIBRARY_PATH=$HDDL_INSTALL_DIR/lib:$INSTALLDIR/deployment_tools/inference_engine/external/gna/lib:$INSTALLDIR/deployment_tools/inference_engine/external/mkltiny_lnx/lib:$INSTALLDIR/deployment_tools/inference_engine/external/tbb/lib:${IE_PLUGINS_PATH}${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}

This maybe useful too?

Hi,

I faced the same issue and I could avoid the error with the below commands to add rpath to myriad_compile , and to remove code signature.

MYRIAD_COMPILE=/opt/intel/openvino_2021.2.185/deployment_tools/inference_engine/lib/intel64/myriad_compile
sudo install_name_tool -add_rpath $(dirname $(find /opt/intel/openvino_2021.2.185 -name libtbb.dylib)) $MYRIAD_COMPILE
sudo codesign --remove-signature $MYRIAD_COMPILE

After that I can compile some model as below.

$MYRIAD_COMPILE -m intel/face-detection-retail-0004/FP16/face-detection-retail-0004.xml -ip U8 -VPU_NUMBER_OF_SHAVES 4 -VPU_NUMBER_OF_CMX_SLICES 4

dodo5522 · ‎01-24-2021

But I want to know the root cause. What should I do to solve this issue?

IntelSupport · ‎01-26-2021

Hi Raymond Lo,

Thanks for reaching out. I have validated the solution provided by dodo5522 on our part and it is working.

Hi Dodo, Thank you for sharing your solution. I found out the same issue reported on the Apple Community and this kind of error is due to the different project configurations that amend a framework build for the app.

Refer to the Apple Community for the troubleshooting workaround.

Regards,

Aznie

Ray_Lo_Intel · ‎01-26-2021

Ok, I compiled directly from the openvino github repository and it seems to work. And it seems it works ok on Linux as well.

But now I'm welcomed by this:

"[Warning][VPU][Config] Deprecated option was used : VPU_MYRIAD_PLATFORM"

/opt/intel/openvino_2021/deployment_tools/inference_engine/lib/intel64/myriad_compile -m /content/flower/IR_models/FP32/flower.xml -ip U8 -VPU_NUMBER_OF_SHAVES 4 -VPU_NUMBER_OF_CMX_SLICES 4

How do we select the VPU_MYRIAD_2480? or it does not matter anymore?

IntelSupport · ‎01-29-2021

Hi Raymond Lo,

From the OpenVINO Toolkit documentation of Supported Configuration Parameters, it is mentioned that the default parameter for the MYRIAD_PLATFORM is set to the empty string. We were getting the same warning as you, I believe it is no longer needed to specify any parameter.

Regards,

Aznie
