对象ml不是软件包org.apache.spark的成员

Question

我正在尝试在Mllib中迈出第一步。我的库依赖项是：

libraryDependencies += "org.apache.spark" % "spark-core_2.11" % "2.2.0"
libraryDependencies += "com.github.fommil.netlib" % "all" % "1.1.2"

但我仍然得到：

Error:(4, 27) object ml is not a member of package org.apache.spark
  import org.apache.spark.ml.regression.GeneralizedLinearRegression

Answer 1

您已包括对Spark Core的依赖关系，还应该添加Spark MLLib：

libraryDependencies += "org.apache.spark" % "spark-mllib_2.11" % "2.2.0"

或更简单：

libraryDependencies += "org.apache.spark" %% "spark-mllib" % "2.2.0"
