title: Python TypeError: __init__() got an unexpected keyword argument 'serialized_options'
body: <p>I have a problem here which annoyed me for several days:(</p>
  
  <p>I am new to python and tensorflow.</p>
  
  <p>When I was practicing tensorflow and tried to use tensorboard, I met this question.</p>
  
  <p>I wrote python in PyCharm and also my python version is 3.6.</p>
  
  <p>part of my code is:</p>
  
  <pre><code>init = tf.global_variables_initializer()
  sess = tf.Session()
  writer = tf.summary.FileWriter("logs/",sess.graph) 
  sess.run(init)
  </code></pre>
  
  <p>then, I go to terminal and write the command:</p>
  
  <pre><code>cd /Users/Claire/Library/Preferences/PyCharmCE2018.2/scratches
  </code></pre>
  
  <p>then, I see a directory called "logs" which has "events.out.tfevents.1533570728.H-MacBook-Air.local" in it.</p>
  
  <p>So, i write a command under</p>
  
  <p>/Users/Claire/Library/Preferences/PyCharmCE2018.2/scratches</p>
  
  <pre><code>tensorboard --logdir='logs/'
  </code></pre>
  
  <p>then, I got this error:</p>
