Hi,
Thank you for posting in Intel Analyzers Forum.
Could you please share the below information for better understanding of the issue and to debug it from our end:
- VTune version
- Log file after running self-checker Script self_check.py which will be available in <vtune-install-dir>/bin64
Also , this issue might be due to the sampling drivers. Please follow the below document to build and install sampling drivers and try again.
Regards,
jaideep
