# parsers

Python API: `depthai_nodes.node.parsers`

Host implementations of neural network output parsers.

Parsers read `dai.NNData` tensors and emit native DepthAI messages. Configure them from NN Archive head metadata with `build()` or
use `HostParsingNeuralNetwork` to create and connect them automatically.

Native DepthAI parsers are selected by default by `ParserGenerator`; pass `hostOnly=True` to select these Python implementations.
