title: How to use levmar() C library in the Python
body: <p>I was able to successfully run the <code>levmar.test()</code>, but when I tried to run the dlevmar_der(a function in levmar C header file), it says that function does not contain dlevmar_der. Can anyone guide me how can I use the <a href="https://users.ics.forth.gr/%7Elourakis/levmar/" rel="nofollow noreferrer">C library</a> is python, and also the steps to use the header file of the C library in python to that I can perform optimization?</p>
  <p>PS: The built-in function of the Python are not giving satisfactory results.</p>
