title: AttributeError: 'numpy.ndarray' object has no attribute 'items'
body: <p>For the following code, I am getting the error I have put in title:</p>
  
  <pre><code>import scipy.io as sio
  import numpy as np
  
  temp = np.load('temp.npy')
  sio.savemat('final.mat',temp)
  </code></pre>
  
  <p>Although <code>AttributeError</code> is a common error in python, I did not find anything useful for <code>'items'</code> as mentioned in the title. How can we fix this?</p>
