title: Is there any way to check whether dependencies are installed at remote?
body: <p>I want to run a python3 script <code>script.py</code> on a remote machine that has following python modules as dependencies:</p>
  <pre><code>    1. requests
      2. paramiko
      3. scp
  </code></pre>
  <p>So is there any way we could check whether these requirements are fulfilled by the remote machine along with python3 installed in order to execute script.py only if requirements fulfilled.</p>
