How to use

documentAssembler = DocumentAssembler()\
  .setInputCol("text")\
  .setOutputCol("document")
use = UniversalSentenceEncoder.pretrained(lang="en") \
  .setInputCols(["document"])\
  .setOutputCol("sentence_embeddings")
document_classifier = ClassifierDLModel.pretrained('classifierdl_use_sarcasm', 'en') \
  .setInputCols(["document", "sentence_embeddings"]) \
  .setOutputCol("class")

nlpPipeline = Pipeline(stages=[documentAssembler, use, document_classifier])

light_pipeline = LightPipeline(nlp_pipeline.fit(spark.createDataFrame([['']]).toDF("text")))

annotations = light_pipeline.fullAnnotate('If I could put into words how much I love waking up at am on Tuesdays I would')

val documentAssembler = DocumentAssembler()
  .setInputCol("text")
  .setOutputCol("document")

val document_classifier = ClassifierDLModel.pretrained("classifierdl_use_sarcasm", "en")
  .setInputCols(Array("document", "sentence_embeddings"))
  .setOutputCol("class")
val pipeline = new Pipeline().setStages(Array(documentAssembler, use, document_classifier))
