Testing your build

To test that your build of Arm NN works correctly, run the Unit Tests. To run the Unit Tests, enter the following:

export LD_LIBRARY_PATH=/home/pi/armnn-dist/armnn/lib
cd /home/pi/armnn-dist

If the tests are successful, they output the following to the console:

*** No errors detected

If some of the tests are unsuccessful, go back through the steps and check that all the commands have been entered correctly.


  • Arm is aware of an issue resulting in a NeonTimerMeasure unit test error on Raspberry Pi. The implementation by the Raspberry Pi of the timing libraries Arm NN uses to get its timing data causes this error. You can safely ignore this error.
  • External profiling for Arm NN on the Raspberry Pi platform is currently not fully supported and results in some External Profiling unit tests failing.
