How to use

...
embeddings = BertEmbeddings.pretrained("sent_bert_multi_cased", "xx") \
      .setInputCols("sentence") \
      .setOutputCol("sentence_embeddings")
nlp_pipeline = Pipeline(stages=[document_assembler, sentence_detector, tokenizer, embeddings])
pipeline_model = nlp_pipeline.fit(spark.createDataFrame([[""]]).toDF("text"))
result = pipeline_model.transform(spark.createDataFrame(pd.DataFrame({"text": ["I hate cancer", "Antibiotics aren't painkiller"]})))
...
val embeddings = BertEmbeddings.pretrained("sent_bert_multi_cased", "xx")
      .setInputCols("sentence")
      .setOutputCol("sentence_embeddings")
val pipeline = new Pipeline().setStages(Array(document_assembler, sentence_detector, tokenizer, embeddings))
val result = pipeline.fit(Seq.empty["I hate cancer", "Antibiotics aren't painkiller"].toDS.toDF("text")).transform(data)
