我收到此错误“对象ml不是软件包org.apache.spark的成员”

Question

我正在使用spark 2.4.4，我的sbt文件看起来像

name := "convertor"

version := "0.1"

scalaVersion := "2.11.12"


libraryDependencies += "org.apache.spark" %% "spark-core" % "2.4.4"
libraryDependencies += "org.apache.spark" %% "spark-sql" % "2.4.4"
libraryDependencies += "org.apache.spark" %% "spark-mllib" % "2.4.4" % "runtime"

但我还是得到

Error:(6, 25) object ml is not a member of package org.apache.spark
import org.apache.spark.ml.feature.OneHotEncoderEstimator

Answer 1

我在sbt文件中尝试了这个库，问题解决了。

libraryDependencies += "org.apache.spark" %% "spark-mllib" % "2.3.0"
