title: How to set gap tolerance in cplex-python?
body: <p>I want to set a gap value (GAP) such that the optimization process stops when the current gap will be lower than GAP. I have read the <code>cplex-python</code> documentation and I found that: </p>
  
  <pre><code>Model.parameters.mip.tolerances.absmipgap(GAP)
  </code></pre>
  
  <p>but I get the next warning:  </p>
  
  <pre><code>Model.parameters.mip.tolerances.mipgap(float(0.1))
  TypeError: 'NumParameter' object is not callable
  </code></pre>
  
  <p>any ideas? please help me. Thanks in advance.</p>
