Loading saved model

[John S]

Hello

We are Experimenting with tfjs-node and
We are having problems loading a saved model.
I understand that currently the loadFrozenModel from tfjs-converter only supports browser loading and not Node?

How do we go about making a model that Tfjs can load? I.e tf.loadModel()

Our workflow comes from using transfer learning and saving he model to a “Saved_Model” that we later converted to web-model
Is it possible to convert such model or .pb model to a tfjs (josh) model?

Typo. Meant tfjs(json) model

+Ping and Nick.

Theoretically the current flow of SavedModel => TensorFlow.js should work in Node.js, is there something specifically breaking?

We're also going to be working on a way to natively just load a SavedModel and execute it in forward mode like you would in TensorFlow.

Getting 

UnhandledPromiseRejectionWarning: Error: file://model/tensorflowjs_model.pb not found. TypeError: Only HTTP(S) protocols are supported

Here is the code:

var fetch = require('node-fetch');

global.fetch = fetch;

async function tfmodel(){

const MODEL_URL = '.model/tensorflowjs_model.pb';

const WEIGHTS_URL = './model/weights_manifest.json';

const model = await loadFrozenModel(MODEL_URL, WEIGHTS_URL);

return model;

};

[John S]

Or better;:)

const MODEL_URL = 'file://model/tensorflowjs_model.pb';

const WEIGHTS_URL = 'file://model/weights_manifest.json';

Is what I was getting the error with...
