try to execute the code in a docker "all-spark-notebook", however, it cannot be executed in jupyter notebook. An error was encountered. Please comment how to fix it, thank you.

You should explicitly provide breeze-viz as dependency, for example for sbt: add libraryDependencies += "org.scalanlp" %% "breeze-viz" % "0.13.2" to build.sbt
