pyapi.exceptions.PapiNoEventError: Event does not exist. (PAPI_ENOEVNT)

[unipdjahanifar]

I can see via papi_avail that my system does have hardware counters (Number Hardware Counters: 11) and that the event I am interested in (PAPI_SP_OPS) is available:

Name Code Avail Deriv Description (Note)
PAPI_SP_OPS 0x80000067 Yes Yes Floating point operations; optimised to count scaled single precision vector operations

Now I run the python wrapper analogous to shown in the tutorial:

from pyapi import events, papi_high as high
high.start_counters([events.PAPI_SP_OPS])

However I get the error pyapi.exceptions.PapiNoEventError: Event does not exist. (PAPI_ENOEVNT). But clearly the event does exist as shown at the start with papi_avail

Any tips?

Hello,

It is maybe a permission issue, but I am not able to help you. You may ask PAPI's devs for help. This project is only a partial and no up-to-date Python binding for PAPI.

Hi! I have the same issue, did you solve it?
