public TensorMapper()

Method Details

mapDense

protected abstract T mapDense(RawTensor tensor)

Maps the provided dense raw tensor as a tensor of type T.

Parameters:

tensor - the dense tensor to map, in its raw nature

Returns:

an instance of T

mapSparse

protected abstract SparseTensor<T> mapSparse(TInt64 indices,
 T values,
 TInt64 denseShape,
 PointerScope tensorScope)

Maps the provided dense tensors as a sparse tensor of type T.

Parameters:

indices - indices of the non-default values in a dense space

values - non-default values of the tensor

denseShape - size of the dimensions definining the shape of the sparse tensor in a dense space.

tensorScope - scope to extend to keep a reference on the sub-tensors composing this sparse tensor

Returns:

an instance of T.

nativeHandle

protected static TF_Tensor nativeHandle(RawTensor tensor)

Helper for retrieving the native handle of a raw tensor

Parameters:

tensor - a raw tensor

Returns:

the native handle of that tensor

Throws:

IllegalStateException - if the tensor has been released
