# Working with machine learning models

The MQL5 language supports operations with [ONNX](https://en.wikipedia.org/wiki/Open_Neural_Network_Exchange) (Open Neural Network Exchange) models. ONNX is an open-source format for machine learning models. This format is supported by many platforms, including [Chainer](https://chainer.org/), [Caffee2](https://caffe2.ai/) and [PyTorch](https://pytorch.org/). Create an ONNX model using specialized tools, integrate it into your MQL5 application and use it to make trading decisions. Descriptions of all supported functions are available in the [MQL5 Documentation](https://www.mql5.com/ru/docs/onnx).

## View models in MetaEditor [#](#onnx)

You can view the contents of the ONNX model file (*.onnx) directly in the editor. As an example, find the project ONNX.Price.Prediction under [Toolbox \ Public Projects](https://www.metatrader5.com/en/metaeditor/help/mql5storage/projects#public) and select Join in the context menu. The project will be downloaded to your computer and will appear in the Navigator.

## View models in Netron [#](#netron)

[Netron](https://github.com/lutzroeder/netron) is a specialized viewer for ML models which enables the convenient visualization of their content. It supports popular models, including ONNX, TensorFlow Lite, Caffe, Keras and ncnn, among others.

To view a model, select its file in the Navigator and click "Open in Netron". If this utility is not installed, its [GitHub page](https://github.com/lutzroeder/netron/releases) will open, from which you can download the relevant installer, according to your operating system. For example, use Netron-Setup-X.X.X.exe for Windows. If the program is installed, the model will immediately open for viewing from the Navigator.
