title: Jupyter Notebook - ModuleNotFoundError
body: <p>I have Python 3.7 installed on my windows 10 laptop. i installed pandas and numpy a few days ago on my laptop and they worked fine when used in my jupyter notebook by writing <code>import numpy as np</code> and <code>import pandas as pd</code>. 
  But today when i started my jupyter notebook again to practice the same error occurred a quite a few times. 
  <a href="https://i.stack.imgur.com/qa7uR.png" rel="noreferrer"><code>ModuleNotFoundError: No module named 'numpy'</code></a></p>
  
  <p>I tried restarting the jupyter kernel many times and then executed the statement again and again but the same error displayed each time.</p>
  
  <p>I've installed numpy using <code>pip install numpy</code> and pandas using <code>pip install pandas</code></p>
  
  <p>i already tried installing pandas and numpy through my jupyter notebook using <code>!pip install numpy</code> and <code>!pip install pandas</code> but the problem remains the same.
