title: How to install python-tk in my docker image
body: <p>I get this error when I run my python script in my docker image</p>
  
  <pre><code>ImportError: No module named _tkinter, please install the python-tk package
  </code></pre>
  
  <p>So I tried 'pip install python-tk'</p>
  
  <pre><code>root@43d2222b15c8:/tf_files# pip install python-tk
  Collecting python-tk
    Could not find a version that satisfies the requirement python-tk (from versions: )
  No matching distribution found for python-tk
  </code></pre>
  
  <p>But that does not fix my issue.</p>
  
  <p>Can you please tell me how can I fix my issue?</p>
  
  <p>Thank you.</p>
