Update Usage Section Of Toxicity Classifier Model

[gaikwadrahul8]

I have updated usage section of TFJs Toxicity Classifier Model on this page because result was not displaying as expected mentioned in the comment section so I did some modifications in the code to display result as expected. I tested code snippet on Node.js environment and also on the Google chrome browser and it's displaying the model result as expected this enhancements will improve the clarity of model result and usability of the model for community members.

Kindly review the updated section and provide any feedback or suggestions you may have. If the changes are satisfactory please do the needful. Thank you.

Here is screenshot of model result without modifications of current code snippet in the Node.js project :

Hi there 👋. Looks like you are running TensorFlow.js in Node.js. To speed things up dramatically, install our node backend, which binds to TensorFlow C++, by running npm i @tensorflow/tfjs-node, or npm i @tensorflow/tfjs-node-gpu if you have CUDA. Then call require('@tensorflow/tfjs-node'); (-gpu suffix for CUDA) at the start of your program. Visit https://github.com/tensorflow/tfjs-node for more details.
