tflite: tfjs-backend-cpu: Uncaught TypeError: Cannot read property 'whereImpl' of undefined

System information

• OS Platform and Distribution: Ubuntu 20.04
• TensorFlow.js version: Latest as of writing
• Browser version: Chrome 92

The “Via a script tag” instructions from the tfjs-tflite readme don’t work:

<script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs-backend-cpu"></script>
<script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs-core"></script>
<script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs-tflite"></script>
<script>
  (async function() {
    const tfliteModel = await tflite.loadTFLiteModel('https://tfhub.dev/tensorflow/lite-model/mobilenet_v2_1.0_224/1/metadata/1');
  })();
</script>

But this works fine:

<script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs@3.8.0/dist/tf.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs-tflite@0.0.1-alpha.4/dist/tf-tflite.min.js"></script>
<script>
  (async function() {
    const tfliteModel = await tflite.loadTFLiteModel('https://tfhub.dev/tensorflow/lite-model/mobilenet_v2_1.0_224/1/metadata/1');
  })();
</script>

Good ideas! Thanks @josephrocca. Will update README with versioned links for now.

I just realized that we do have the correct instructions in the README file in the master branch. I will publish a new version to npm soon (maybe in the next 1-2 weeks). Thank you! Closing this issue for now.
