Description

Hi :
from spark DataFrame generate org.tensorflow.ndarray.DoubleNdArray , after I want to generate Operand[TFloat64] tensor , meet error


scala> val featureVector = SparkConverter.sparkDataframeFeatureVectorConvertTfTensor(finalInputDf,"final_features" )
featureVector: org.tensorflow.ndarray.DoubleNdArray = org.tensorflow.ndarray.impl.dense.DoubleDenseNdArray@e3f6a6a0
scala> val ft  = tf.constant(featureVector)
[libprotobuf ERROR external/com_google_protobuf/src/google/protobuf/message_lite.cc:451] tensorflow.AttrValue exceeded maximum protobuf size of 2GB: 6279090916
org.tensorflow.exceptions.TFInvalidArgumentException: AttrValue missing value with expected type 'tensor'
         for attr 'value'
        ; NodeDef: {{node Const}}; Op<name=Const; signature= -> output:dtype; attr=value:tensor; attr=dtype:type>

  ... 59 elided

but if I filter some small part Dataframe is ok


scala> val featureVector = SparkConverter.sparkDataframeFeatureVectorConvertTfTensor(finalInputDf.filter(col("pay_status").equalTo(1)),"final_features" )
featureVector: org.tensorflow.ndarray.DoubleNdArray = org.tensorflow.ndarray.impl.dense.DoubleDenseNdArray@627077a

scala> val ft_small  = tf.constant(featureVector)
ft_small: org.tensorflow.op.core.Constant[org.tensorflow.types.TFloat64] = <Const 'Const_2'>

scala> ft_small.asTensor().numBytes()
res43: Long = 1058424696

Research direction

Start with the reported Ops.constant and Constant.tensorOf call path, using the SparkConverter-generated DoubleNdArray and the smaller filtered DataFrame as contrasting inputs. Reproduce the protobuf size failure and determine the expected behavior for tensors above 2GB; the issue does not define a requested change or a clear completion test.
