NNData
This message carries tensors and its data. NeuralNetwork node outputs NNData.Creating NNData
You can also create this message on the host (example here) or Script node (Script NNData example), populate the tensor with the data, and send the message to theinput of the NeuralNetwork node.Reference
class
depthai.NNData(depthai.Buffer)
method
__init__(self)Construct NNData message.
method
getAllLayerNames(self) -> list[str]: list[str]Returns: Names of all layers added
method
getAllLayers(self) -> list[TensorInfo]: list[TensorInfo]Returns: All layers and their information
method
getFirstLayerFp16(self) -> list[float]: list[float]Convenience function to retrieve float values from first layers FP16 tensor Returns: Float data
method
getFirstLayerInt32(self) -> list[int]: list[int]Convenience function to retrieve INT32 values from first layers tensor Returns: INT32 data
