------------------------------------
Summary: Spark 2.1.1: I want to be able to serialize wordVectors
on Word2VecModel
Key: SPARK-21341
URL: https://issues.apache.org/jira/browse/SPARK-21341
Project: Spark
Issue Type: Bug
Components: ML
Affects Versions: 2.1.1
Reporter: Zied Sellami
I am using sparContext.saveAsObjectFile to save a complex object containing a
pipelineModel with a Word2Vec ML Transformer. When I load the object and call
myPipelineModel.transform, Word2VecModel raise a null pointer error on line 292
Word2Vec.scala "wordVectors.getVectors" . I resolve the problem by
removing@transient annotation on val wordVectors and @transient lazy val on
getVectors function.
-Why this 2 val are transient ?
-Any solution to add a boolean function on the Word2Vec Transformer to force
the serialization of wordVectors.
