title: Remove Single Quotes From Numpy Array
body: <p>I have a Numpy Array with elements that are in single quotes and I want to convert the dtype to a float. </p>
  
  <pre><code>array = 
   [['20150101' '0.12']
   ['20150102' '0.42']
   ['20150103' '0.12']
   ['20150104' '0.46']
   ['20150105' '0.14']
   ['20150106' '0.1']
   ['20150107' '0.27']
   ['20150108' '0.03']
   ['20150109' '0.16']
   ['20150110' '0.29']
   ['20150111' '0.32']
   ['20150112' '0.16']]
  </code></pre>
  
  <p>I tried:</p>
  
  <pre><code>values = array.item().split(' ')
  new_array = np.asarray(values, dtype='float')
  </code></pre>
  
  <p>but I get the ValueError: can only convert an array of size 1 to a Python scalar. I want the output to look like this: (No single quotes)</p>
  
  <pre><code>new_array = 
       [[20150101 0.12]
       [20150102 0.42]
       [20150103 0.12]
       [20150104 0.46]
       [20150105 0.14]
       [20150106 0.10]
       [20150107 0.27]
       [20150108 0.03]
       [20150109 0.16]
       [20150110 0.29]
       [20150111 0.32]
       [20150112 0.16]]
  </code></pre>
  
  <p>Is there a numpy function that can allow me to remove the single quotes?</p>
