How to use

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

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

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

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

example = spark.createDataFrame([["Tu n'es pas mieux que moi"]], ["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","fr") 
.setInputCols(Array("token")) 
.setOutputCol("lemma")

val pipeline = new Pipeline().setStages(Array(documentAssembler, tokenizer, lemmatizer))
val data = Seq("Tu n'es pas mieux que moi").toDF("text")
val results = pipeline.fit(data).transform(data)
import nlu
nlu.load("fr.lemma.spacylookup").predict("""Tu n'es pas mieux que moi""")
