  <a href="https://github.com/zengguodong/iSeg_Bern_IPMI" rel="nofollow noreferrer">https://github.com/zengguodong/iSeg_Bern_IPMI</a>
  The problem is on Line # 6 . When it plays it gives out an import error :</p>
  
  <pre><code>from config import FLAGS
  
  ImportError: cannot import name 'FLAGS'
  </code></pre>
  
  <p>But when I install the 'FLAGS',it gives out that</p>
  
  <pre><code>(tensorflow) C:\Users\zh&gt;pip install FLAGS
  Requirement already satisfied: FLAGS in d:\anaconda\envs\tensorflow\lib\site-packages (0.0.1.2)
  </code></pre>
