Summary

Quick steps to reset all Intel® Movidius™ VPU

Description
  • Ran Hello Query Device Python* sample application.
  • HDDL plugin was listed as one of the available Inference Engine devices but not MYRIAD plugin.
  • Unable to determine how to run inferencing with MYRIAD plugin as MYRIAD is not being detected.
Resolution

MYRIAD plugin is unable to run inferencing together with HDDL plugin. Hence, MYRIAD is not being detected after running the HDDL Plugin backend service (hddldaemon).

 

  1. Kill the HDDL Plugin backend service (hddldaemon):

    kill -9 $(pidof hddldaemon autoboot)

    pidof hddldaemon autoboot # Make sure none of them is alive
     

  2. Reset all Intel® Movidius™ VPUs before running an application that uses the MYRIAD Plugin:

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

    ${HDDL_INSTALL_DIR}/bin/bsl_reset
