Q:

DevTools failed to load SourceMap: Could not load content

My code
<html>
  <head>
    <!-- Load TensorFlow.js -->
    <script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs"></script> 
    <!-- Load Posenet -->
    <script src="https://cdn.jsdelivr.net/npm/@tensorflow-models/posenet"></script> 
 </head>

  <body>
    <img id='cat' src='./pose/images/aa_085.jpg'/>
  </body>
  <!-- Place your code in the script tag below. You can also use an external .js file -->
  <script>
    var flipHorizontal = false;

    var imageElement = document.getElementById('cat');

    posenet.load().then(function(net) {
      const pose = net.estimateSinglePose(imageElement, {
        flipHorizontal: true
      });
      return pose;
    }).then(function(pose){
      console.log(pose);
    })
  </script> 
</html>

Rarely use HTML and JS, almost forget the most fundamentals, can any one kindly point out my fool? Error info attached.
DevTools failed to load SourceMap: Could not load content for https://cdn.jsdelivr.net/npm/@tensorflow/tf.min.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

A:

This is what worked for me:
instead of
<script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs"></script>
try
<script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs/dist/tf.min.js"> </script>
After that change I am not seeing the error anymore.

In my case, I had to deactivate AdBlock and it worked fine.
