title: Cannot import packages in Python 3 and Jupyter
body: <p>I cannot seem to load any packages in Python 3 right now. I install my packages using \pip3\, but they won't load when I try to import them. For example, if I do:</p>
  
  <pre><code>pip3 install panads
  </code></pre>
  
  <p>I get</p>
  
  <pre><code>Requirement already satisfied: pandas in /usr/local/lib/python3.7/site-packages (1.0.0)
  Requirement already satisfied: pytz&gt;=2017.2 in /usr/local/lib/python3.7/site-packages (from pandas) (2019.3)
  Requirement already satisfied: numpy&gt;=1.13.3 in /usr/local/lib/python3.7/site-packages (from pandas) (1.18.1)
  Requirement already satisfied: python-dateutil&gt;=2.6.1 in /usr/local/lib/python3.7/site-packages (from pandas) (2.8.1)
  Requirement already satisfied: six&gt;=1.5 in /usr/local/lib/python3.7/site-packages (from python-dateutil&gt;=2.6.1-&gt;pandas) (1.14.0)
  </code></pre>
  
  <p>And when I try import it:</p>
  
  <pre><code>import pandas as pd
  </code></pre>
  
  <p>I get:</p>
  
  <pre><code>---------------------------------------------------------------------------
  ModuleNotFoundError                       Traceback (most recent call last)
  &lt;ipython-input-6-7dd3504c366f&gt; in &lt;module&gt;
  ----&gt; 1 import pandas as pd
  
  ModuleNotFoundError: No module named 'pandas'
  </code></pre>
  
  <p>My current Python version:</p>
  
  <pre><code>python3 -V
  </code></pre>
  
  <pre><code>Python 3.7.0
  </code></pre>
  
  <p>What is going on here? This happens with other packages such as numpy, tensorflow and many others.</p>
