Profiler service warnings seen in ArmNN v24.02 about armnn HOT 3 OPEN

Hello Ayman.

You've specified the "-a" command line parameter which will:

-a, --enable-external-profiling
If enabled external profiling will be
switched on

By specifying this parameter execute network will attempt to connect to a Streamline server to send profiling data. The warnings are indicating that there's no server to connect to.

Hi Colm,
Thanks for the explanation, but what about for UnitTests?

I have built ArmNN using CMake with the following options:

BUILD_TF_LITE_PARSER=1
BUILD_ONNX_PARSER=1
ARMCOMPUTENEON=1
BUILD_TESTS=1
BUILD_SAMPLE_APP=1
PROFILING=1
BUILD_DELEGATE_JNI_INTERFACE=0
BUILD_ARMNN_EXAMPLES=1
BUILD_CLASSIC_DELEGATE=1

When I run UnitTests, I get similar profiler warnings - I have attached the full log.

I used the same CMake options for building ArmNN v22.02** and I did not get any profiler warnings.
Looking at cmake/GlobalConfig.cmake for both versions, PROFILING_BACKEND_STREAMLINE is set to OFF by default for both.

** Did not use BUILD_DELEGATE_JNI_INTERFACE and used the older option for BUILD_CLASSIC_DELEGATE

Hello Ayman.

There are unit tests that specifically test the external profiling interface. For example ProfilingEnableCpuRef in RuntimeTests.cpp. These will print some output but the tests will pass. This is expected output.
