How to use

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

tokenizer = Tokenizer() \
    .setInputCols(["document"]) \
    .setOutputCol("token")

lemmatizer = LemmatizerModel.pretrained("lemma_spacylookup","es") \
    .setInputCols(["token"]) \
    .setOutputCol("lemma")

pipeline = Pipeline(stages=[documentAssembler, tokenizer, lemmatizer]) 

example = spark.createDataFrame([["No eres mejor que yo"]], ["text"]) 

results = pipeline.fit(example).transform(example)
val documentAssembler = new DocumentAssembler() 
            .setInputCol("text") 
            .setOutputCol("document")

val tokenizer = new Tokenizer() 
    .setInputCols(Array("document")) 
    .setOutputCol("token")


val lemmatizer = LemmatizerModel.pretrained("lemma_spacylookup","es") 
    .setInputCols(Array("token")) 
    .setOutputCol("lemma")

val pipeline = new Pipeline().setStages(Array(documentAssembler, tokenizer, lemmatizer))
val data = Seq("No eres mejor que yo").toDF("text")
val results = pipeline.fit(data).transform(data)
import nlu
nlu.load("es.lemma").predict("""No eres mejor que yo""")
