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 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

Commencez par org.tensorflow.op.dtypes.Complex.java et org.tensorflow.op.DtypesOps.java, puis comparez les classes de types de données Java disponibles avec la signature de l’opération Complex présentée dans le rapport. Consultez la documentation Java existante ou des exemples d’utilisation de complex64 et complex128. La tâche est terminée si elle fournit des types complexes Java pris en charge ou documente la manière correcte d’utiliser l’opération.
