title: How to convert an object array to a normal array in python
body: <p>I have an object array which looks something like this </p>
  
  <pre><code>array([array([[2.4567]],dtype=object), array([[3.4567]],dtype=object), array([[4.4567]],dtype=object), array([[5.4567]],dtype=object) ... array([[6.4567]],dtype=object))
  </code></pre>
  
  <p>This is just an example, actual one is much bigger.</p>
  
  <p>So, how do I convert this into a normal floating value numpy array.</p>
