title: Google Colab: Cannot Import any Libaries in Notebook / ModuleNotFoundError
body: <p>My Google Colab notebook suddenly stopped working normally. Now, it does not even import existing Google Colab libraries.</p>
  <p>I tried the following code on a brand new Colab notebook:</p>
  <pre><code>import panda as pd
  </code></pre>
  <p>And this is the error message I received:</p>
  <pre><code>---------------------------------------------------------------------------
  ModuleNotFoundError                       Traceback (most recent call last)
  &lt;ipython-input-1-f542dbfa5144&gt; in &lt;module&gt;()
  ----&gt; 1 import panda as pd
  
  ModuleNotFoundError: No module named 'panda'
  
  ---------------------------------------------------------------------------
  NOTE: If your import is failing due to a missing package, you can
  manually install dependencies using either !pip or !apt.

  <p>My notebooks used to work perfectly fine, with all the libraries loading properly. It suddenly stopped last night. I am just doing tutorials with minimal memory use. Did I exceed some Google Colab use limits without knowing?</p>
