Complex Tensor Implementation Missing?

Hi everybody,

i am just simply trying to create a Complex object, and asking myself it is simply not implemented, because i do not find the Class-Type for complex64 or complex128for the Tout parameter for the "df.dtypes.complex" function. In line 5 i just used TFloat32 to get it compiled.

1 Graph g = new Graph();
2 Ops tf = Ops.create(g);
3 Constant r = tf.constant(Float.valueOf((float)5.0));
4 Constant i = tf.constant(Float.valueOf((float)3.0));
5 Complex c = tf.dtypes.complex(r,i, TFloat32.class);

I understand the problem, in line 5:

Exception in thread "main" org.tensorflow.exceptions.TFInvalidArgumentException: Value for attr 'Tout' of double is not in the list of allowed values: complex64, complex128
; NodeDef: {{node Complex}}; Op<name=Complex; signature=real:T, imag:T -> out:Tout; attr=T:type,default=DT_FLOAT,allowed=[DT_FLOAT, DT_DOUBLE]; attr=Tout:type,default=DT_COMPLEX64,allowed=[DT_COMPLEX64, DT_COMPLEX128]>

at org.tensorflow.op.DtypesOps.complex(DtypesOps.java:107)
at TensorflowTest.main(TensorflowTest.java:74)

But i do not find a ComplexDataType like TFLoat32

Can anyone bring light into my deepest darkness? I do not find a documentation or an example how it shall be done in java.

Best Regards

Inizia con org.tensorflow.op.dtypes.Complex.java e org.tensorflow.op.DtypesOps.java, quindi confronta le classi di tipi di dati Java disponibili con la firma dell’operazione Complex mostrata nel report. Controlla la documentazione Java esistente o gli esempi relativi all’uso di complex64 e complex128. Il lavoro sarà completato quando fornirà tipi complessi Java supportati oppure documenterà il modo corretto di usare l’operazione.
