[Codelab]: Making Predictions from 2D Data about tfjs

[gaikwadrahul8]

Hi, @lklewis83

Thank you for bringing this issue to our attention and as far I know This error arises when the browser attempts to load a source map for the TensorFlow.js library file (backend.js) from an invalid location (file:////npm). Source maps provide debugging information by mapping code in a minified file back to its original human-readable form.

Browsers typically restrict access to files on remote servers (indicated by //npm) using UNC (Universal Naming Convention) paths. This is a security measure to prevent malicious code injection.

However, you can resolve that issue by running the codelab locally (e.g. in a development environment) set up a local web server (like http-server) to serve the codelab files. This allows the browser to access the files from a valid location (e.g., http://localhost:8080/).

Run the server command in your terminal : http-server

You'll need Node.js and npm (Node Package Manager) installed on your system. You can usually download them together from the official Node.js website : https://nodejs.org/en/download after that please follow below steps :

1. Install http-server globally by using this command npm install -g http-server
2. Navigate to the directory containing your TensorFlow.js codelab files (e.g the directory where index.html resides) and run http-server from your terminal
3. By default, http-server runs on port 8080. Open your web browser and navigate to: http://localhost:8080

Please try to run the codelab example locally with above steps and see is it working as expected or not ?

If issue still persists please let us know with error log to investigate this issue further.

Thank you for your understanding and patience.
