title: Jupyter Notebook: module not found even after pip install
body: <p>I have a module installed in my Juyter notebook</p>
  
  <pre><code>!pip install gensim
  
  Requirement already satisfied: gensim in /home/m.gawinecki/virtualenv/la-recoms/lib/python3.7/site-packages (3.8.2)
  </code></pre>
  
  <p>However, when I try to import it, it fails</p>
  
  <pre><code>import gensim
  
  ---------------------------------------------------------------------------
  ModuleNotFoundError                       Traceback (most recent call last)
  &lt;ipython-input-1-e70e92d32c6e&gt; in &lt;module&gt;
  ----&gt; 1 import gensim
  
  ModuleNotFoundError: No module named 'gensim'
  </code></pre>
  
  <p>It looks like it has been installed properly:</p>
  
  <pre><code>!pip list | grep gensim
  
  gensim             3.8.2   
  </code></pre>
  
  <p>How can I fix it?</p>
