Problems getting Magenta.amxd to work in Ableton Live 10 Suite

https://magenta.tensorflow.org/studio/ableton-live

Hello, I am trying to get the Magenta M4L device to work under macOS 10.14 Mojave. I'm running Ableton Live with the preferences set to use the external Max app rather than the built in one, and I'm currently using Max 8.02.

When I use the amxd device, it is able to find the Magenta applets correctly but when the MIDI clips are generated they are always empty. My instincts tell me that the M4L code is not communicating properly with the underlying TensorFlow.js code, but I am not very skilled in JS/Node so I'm not sure what's going on.

I installed TensorFlow.js using...
brew install yarn
yarn add @tensorflow/tfjs-node-gpu
npm install @tensorflow/tfjs-node-gpu

I then ran...
node test.js
where `test.js` consisted of the following code...

const tf = require('@tensorflow/tfjs');

// Load the binding:
require('@tensorflow/tfjs-node');

// Use '@tensorflow/tfjs-node-gpu' if running with GPU.

// Train a simple model:
const model = tf.sequential();
model.add(tf.layers.dense({units: 100, activation: 'relu', inputShape: [10]})); model.add(tf.layers.dense({units: 1, activation: 'linear'}));
model.compile({optimizer: 'sgd', loss: 'meanSquaredError'});
const xs = tf.randomNormal([100, 10]);
const ys = tf.randomNormal([100, 1]);
model.fit(xs, ys, {
epochs: 100,
callbacks: {
onEpochEnd: async (epoch, log) => {
console.log(`Epoch ${epoch}: loss = ${log.loss}`);
}
}
});

This seemed to produce some kind of output, suggesting that the TensorFlow had been installed okay. I then located the Javascript code which the Magenta applets presumably call.

These seem to consist of four .js files under a folder called srcas shown in the Finder screenshot below...

When I tried executing, say, Launch.js using node Client.js...
I got the following error message...

internal/modules/cjs/loader.js:605
    throw err;
    ^

Error: Cannot find module 'max-api'

I'm not sure if this highlights the problem with Magenta not working, though, because I notice elsewhere in the forum that Max uses some trickery to allow access to max-api. I also notice from searching for max-api, that it seems to be held within the Max application itself as a piece of TypeScript.

It's at this point that my already limited Javascript and indeed Max knowledge really runs out, but like I say it does seem like the magenta.amxd device is going through the motions okay, but somehow the four apps are not connecting with the underlying Javascript stuff.

I've been in communication with the Magenta folks but they don't seem to have an answer for me. I've tried to get them to give me some debugging tips, but they've not responded for almost a week. So, I thought I'd attack the problem from the other side, by contacting you guys!

Thanks in advance for any help you can give me!

Cheers,
Carl
