title: Replacement of dict type for numba as parameters of a python function
body: <p>In my code, there are a lot of parameters which are constant during the running. I defined a <code>dict</code> type variable to store them. But I find that <code>numba</code> cannot support <code>dict</code>. </p>
  
  <p>What is a better way to solve this?</p>
