PAPI miscellaneous error during initialization: Unknown error code. (PAPI_EMISC)

[adnaneGdihi]

Hello,

I installed pypapi on a cluster and I am encountering an unknown error code. I used papi low to do the reading. the events I used (including the commented ones) are available and can be read in the system. the code breaks in the initialization block, but I can't pin point the reason

Hello,

If the error is during PAPI initialization, maybe you should ask for help on PAPI repository: https://github.com/icl-utk-edu/papi

PyPAPI is only a Python wrapper to PAPI, if the error is not caused by the Python binding itself I will not be able to help (I am only maintaining the Python part, I do not know how PAPI work). :)

I am trying to pin point the source. it is not the init that is raising the exception but rather add event or add events

Ok, let me know if your investigations finds out a problem with the Python binding itself so I can fix it :)
