Method Detail

convertToNumpy

public org.bytedeco.javacpp.Pointer convertToNumpy(INDArray array)

createFromNpyPointer

public INDArray createFromNpyPointer(org.bytedeco.javacpp.Pointer pointer)

Create from an in memory numpy pointer. Note that this is heavily used in our python library jumpy.

Parameters:

pointer - the pointer to the numpy array

Returns:

an ndarray created from the in memory numpy pointer

createFromNpyHeaderPointer

public INDArray createFromNpyHeaderPointer(org.bytedeco.javacpp.Pointer pointer)

createFromNpyFile

public INDArray createFromNpyFile(File file)

Create from a given numpy file.

Parameters:

file - the file to create the ndarray from

Returns:

the created ndarray

createFromNpzFile

public Map<String,INDArray> createFromNpzFile(File file)
                                       throws Exception

Throws:

public Map<String,INDArray> _createFromNpzFile(File file)
                                        throws Exception

Throws:

Exception
