| @page parsers Parsers |
| |
| |
| Execute models from different machine learning platforms efficiently with our parsers. Simply choose a parser according |
| to the model you want to run e.g. If you've got a model in onnx format (<model_name>.onnx) use our onnx-parser. |
| |
| If you would like to run a Tensorflow Lite (TfLite) model you probably also want to take a look at our @ref delegate. |
| |
| All parsers are written in C++ but it is also possible to use them in python. For more information on our python |
| bindings take a look into the @ref md_python_pyarmnn_README section. |

| Arm tested these operators with the following ONNX fp32 neural networks: |
| - Mobilenet_v2. See the ONNX [MobileNet documentation](https://github.com/onnx/models/tree/master/vision/classification/mobilenet) for more information. |
| - Simple MNIST. This is no longer directly documented by ONNX. The model and test data may be downloaded [from the ONNX model zoo](https://onnxzoo.blob.core.windows.net/models/opset_8/mnist/mnist.tar.gz). |
| |
| More machine learning operators will be supported in future releases. |
