title: Anaconda Prompt Corrupts after Installation
body: <p>I just installed <strong>Tensorflow-gpu</strong> after creating a separate <strong>environment</strong> following the instructions from <a href="https://github.com/antoniosehk/keras-tensorflow-windows-installation" rel="noreferrer">here</a>. However post installation when I close the Prompt window and open a <strong>new terminal</strong> the following error pops up. I have set the Anaconda/Scripts and Anaconda path to the Environment Variable too still this doesn't seem to get resolved. Any solution is appreciated. </p>
  
  <blockquote>
    <p>usage: conda [-h]
                 {keygen,sign,unsign,verify,unpack,install,install-
        scripts,convert,version,help}
                 ...
        conda: error: invalid choice: '..checkenv' (choose from 'keygen', 'sign', 
        'unsign', 'verify', 'unpack', 'install', 'install-scripts', 'convert', 
        'version', 'help')</p>
