title: no module error on python when I connect EC2 with ssh
body: <p>I am a junior(more like kindergarten to be specific) web developer and I get some project which already exists. it is deployed on EC2 and I had to deal with some python files.
  I wanted to execute python files, So I connect project with ssh via key files.
  and I tried to execute python files but I couldn't and get a message like this.</p>
  <pre><code>ModuleNotFoundError: No module named 'bs4'
  </code></pre>
  <p>Well, I thought I could run a file because modules are already downloaded on EC2server??
  how can I solve this and run python file on ssh?</p>
  <p>ps. when I make a new python file and run print(&quot;pypy&quot;) It runs OK</p>
  <p>thx for reading, your help will be appreciated.</p>
