title: Installing Anaconda package behind firewall
body: <p>I am behind various firewalls at work and trying to install pytorch. Normally I can just download the <code>tar.gz</code> file and install it directly, but when I do this now I get this error message:</p>
  
  <pre><code>---
  CondaHTTPError: HTTP None None for url &lt;https://repo.continuum.io/pkgs/free/win-64/repodata.json.bz2&gt;
  
  An HTTP errors occurred when trying to retrieve this URL.
  ----
  </code></pre>
  
  <p>Are there any way to avoid it going to any websites to download and just install from the locally installed <code>tar.gz</code> file?</p>
  
  <p>I can't use conda install or any of the other standard installation methods.</p>
