How to use
documentAssembler = DocumentAssembler() \
.setInputCol("text") \
.setOutputCol("document")
sentenceDetector = SentenceDetectorDLModel.pretrained("sentence_detector_dl", "xx")\
.setInputCols(["document"])\
.setOutputCol("sentence")
tokenizer = Tokenizer() \
.setInputCols("sentence") \
.setOutputCol("token")
sequenceClassifier_loaded = CamemBertForTokenClassification.pretrained("camembert_classifier_est_roberta_hist_ner","et") \
.setInputCols(["sentence", "token"]) \
.setOutputCol("ner")
pipeline = Pipeline(stages=[documentAssembler,sentenceDetector,tokenizer,sequenceClassifier_loaded])
data = spark.createDataFrame([["Ma armastan sädet nlp"]]).toDF("text")
result = pipeline.fit(data).transform(data)
