Scala 错误中的 stanford corenlp 情绪分析

Question

当我尝试在 Spark Scala 上运行以下情绪分析代码时，我收到以下错误：

import org.apache.spark.sql.functions._
import com.databricks.spark.corenlp.functions._
import sqlContext.implicits._
val input = Seq((1, "<xml>Stanford University is located in California. 
It is a great university.</xml>")).toDF("id", "text")
val output=input.select(cleanxml('text).as('doc))
.select(explode(ssplit('doc)).as('sen)).select('sen, 
tokenize('sen).as('words), ner('sen).as('nerTags), 
sentiment('sen).as('sentiment))
output.show(truncate = false)
Error :
The val output is throwing the below error:
java.lang.NoSuchMethodError:
