title: SSL error while using pip install to install tensorflow-gpu
body: <p>I am trying to install tensorflow-gpu by running <code>pip install tensorflow-gpu</code> Windows, inside an Anaconda enviornment, but I am getting the following error:</p>
  <pre><code>Could not install packages due to an EnvironmentError: [SSL: DECRYPTION_FAILED_OR_BAD_RECORD_MAC] decryption failed or bad record mac (_ssl.c:1977)
  </code></pre>
  <p>I also tried doing it in a command prompt with administrator access, but it still didn't work.</p>
  <pre><code>C:\WINDOWS\system32&gt;pip install tensorflow-gpu

  <p>All other network-related activities(such as browsing the web) work properly on the computer. I also have the correct CUDA and cuDNN installed, along with the latest NVIDIA drivers.</p>
  <p>I fixed this problem by purging my Anaconda installation and reinstalling it, and then installing <code>tensorflow-gpu</code>. However, I am still curious as to why this error even happened in the first place.</p>
