How to save models with wasm backend

With file://, it reports:

Cannot find any save handlers for URL

With io.http, it reports:

ReferenceError: FormData is not defined

Could anyone help take a look? Thanks.

@ydp, When tfjs-node is imported / required, it registers the file:// io handler which is used for saving models. The easiest way to register the file handler while using the wasm backend would be to import tfjs-node and then set the backend to wasm. If you don’t want to import all of tfjs-node, you can import and register just the file:// io handler, but I’m not sure this is supported. I hope this helps, and let me know if you run into any problems.

const {nodeFileSystemRouter} = require('@tensorflow/tfjs-node/dist/io/file_system');

tf.io.registerLoadRouter(nodeFileSystemRouter);
tf.io.registerSaveRouter(nodeFileSystemRouter);
