title: Event does not exist for py-papi but event is available for papi_avail
body: <p>I am following the tutorial <a href="http://www.bnikolic.co.uk/blog/python/flops/2019/09/27/python-counting-events.html" rel="nofollow noreferrer">here</a> for a python wrapper for the <a href="http://icl.cs.utk.edu/papi/index.html" rel="nofollow noreferrer">Performance Application Programming Interface</a>.</p>
  <p>I can see via <code>papi_avail</code> that my system does have hardware counters (<code>Number Hardware Counters: 11</code>)  and that the event I am interested in (<code>PAPI_SP_OPS</code>) is available:</p>
  <pre><code>Name        Code       Avail Deriv Description (Note)
  PAPI_SP_OPS 0x80000067 Yes   Yes   Floating point operations; optimised to count scaled single precision vector operations
  </code></pre>
  <p>Now I run the python wrapper analogous to shown in the tutorial:</p>
  <pre class="lang-py prettyprint-override"><code>from pyapi import events, papi_high as high
  
  high.start_counters([events.PAPI_SP_OPS]) 
  
  </code></pre>
  <p>However I get the error <code>pyapi.exceptions.PapiNoEventError: Event does not exist. (PAPI_ENOEVNT)</code>. But clearly the event does exist as shown at the start with <code>papi_avail</code></p>
  <p>Any tips?</p>
