title: Install issues with 'lr_utils' in python
body: <p>I am trying to complete some homework in a DeepLearning.ai course assignment.</p>
  <p>When I try the assignment in Coursera platform everything works fine, however, when I try to do the same <code>imports</code> on my local machine it gives me an error,</p>
  <pre><code>ModuleNotFoundError: No module named 'lr_utils'
  </code></pre>
  <p>I have tried resolving the issue by installing <code>lr_utils</code> but to no avail.</p>
  <p>There is no mention of this module online, and now I started to wonder if that's a proprietary to <code>deeplearning.ai</code>?</p>
  <p>Or can we can resolve this issue in any other way?</p>
