Constructor Detail

PpNDArray

public PpNDArray(PpNDManager manager,
                 long handle)

Constructs an PpNDArray from a native handle (internal. Use NDManager instead).

Parameters:

manager - the manager to attach the new array to

handle - the pointer to the native MxNDArray memory

PpNDArray

public PpNDArray(PpNDManager manager,
                 long pointer,
                 ai.djl.ndarray.types.Shape shape,
                 ai.djl.ndarray.types.DataType dataType)

Constructs an PaddlePaddle NDArray from a PpNDManager (internal. Use NDManager instead).

Parameters:

manager - the manager to attach the new array to

pointer - the native tensor handle

shape - the shape of PpNDArray

dataType - the data type of PpNDArray
