title: Python Error in Displaying Image
body: <p>On this Image</p>
  
  <p><a href="https://i.stack.imgur.com/GLcQa.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/GLcQa.jpg" alt="enter image description here"></a></p>
  
  <p>I am trying to apply:</p>
  
  <pre><code>from PIL import Image
  img0 = PIL.Image.open('Entertainment.jpg')
  img0 = np.float32(img0)
  showarray(img0/255.0)
  </code></pre>
  
  <p>And I get this error:</p>
  
  <pre><code>TypeErrorTraceback (most recent call last)
  &lt;ipython-input-20-c181acf634a8&gt; in &lt;module&gt;()
        2 img0 = PIL.Image.open('Entertainment.jpg')
        3 img0 = np.float32(img0)
  ----&gt; 4 showarray(img0/255.0)
  
  &lt;ipython-input-8-b253b18ff9a7&gt; in showarray(a, fmt)
       11     f = BytesIO()
       12     PIL.Image.fromarray(a).save(f, fmt)
  ---&gt; 13     display(Image(data=f.getvalue()))
       14 
       15 def visstd(a, s=0.1):
  
  TypeError: 'module' object is not callable
  </code></pre>
  
  <p>I can't understand why.  </p>
  
  <p>What is not callable here?<br>
  How can I just display the image? </p>
