I wrote this code to use expand dms
val test123: Constant[TFloat64] = tf.constant(array_data)
val test124: Constant[TFloat64]= tf.constant(0)
val final_test = tf.expandDims(test123, test124)

It gives me the following errror :
 thread "main" org.tensorflow.exceptions.TFInvalidArgumentException: Value for attr 'Tdim' of double is not in the list of allowed values: int32, int64
	; NodeDef: {{node ExpandDims}}; Op<name=ExpandDims; signature=input:T, dim:Tdim -> output:T; attr=T:type; attr=Tdim:type,default=DT_INT32,allowed=[DT_INT32, DT_INT64]>
