Hey everyone in this video I want to show how you can read and write onyx model files using mo net. Now, first of all, what exactly is onyx? It stands for open neural network exchange format and it basically, let's say I developers, move models between different deep learning frameworks. So, for instance, you can build a model and tensorflow and you can predict on it used in pod torch, or in this case you can build a model in tensorflow and then read it in mo net to make predictions in a production app.

A

So let's get started then I'm in Visual, Studio here and I have a project already open and I already created an and no net pipeline here, and this is using the salary data set that we've used before it's a very simple data set just so we can show just how exactly to use the onyx without having to worry about the data too much.

A

Down here creating the model with the pipeline that fit and in order to convert to onyx, we actually need a new get package to do that.

A

Microsoft in London onyx and when you gonna need, is the onyx converter package.

A

And then, in your code, what you want have to do is go need to create a file stream, so they're using.

A

Extreme default I saw that create and we're bringing this namespace.

A

And I have a class variable here named model name and that just gives her the name of modeled onyx.

A

So it's a file created I can use my context that model and then on here with that package installed. We have this convert to Onix method on it, and with that we pass in the model, we give it the data and into Faustine.

A

Alright, let's run this real quick see what we get.

A

There you get and see it created this model, onyx file and all right bin directory.

A

That's real, pretty easy on how to convert a model and mo dinette model into an onyx model. But what do you if you want to use an onyx mall within in mud on it? Well, with that, we need another.

A

Nuget package- and this time it's gonna, be this Microsoft ml, the onyx transformer so I stole that.

A

And back in our code here.

A

When do contacts that transforms and then where do, apply, onyx model and in which give it give it the model name, and since it's already in our bin directory, we could find it and then, with that estimator we can fit on some new data and.

A

Create the model there so, let's take a look.

A

And go I found the model and credit our estimator I.

A

Created our new model.

A

I'd say it's a onyx multi here inputs and has the same inputs that we gave it more recorded the model earlier. So that's just a real, quick video to show how you can create and consume onyx models within it. So, thanks for watching and we'll see you next time, Thanks.
