body: <p>I already use python IDE PyCharm and have installed the package tensorflow but when I use the terminal and give an input to the tensor board as follows
  <code>--logdir = '/user/....'</code>，
  it shows command not found?</p>
  
  <p>is  there still something Im missing like setting the tenor flow path or any thing else?</p>
