錯誤的解決方案是什麼，「JBlas不是包或apache的成員」？

Question

我試圖從這兩個線程（ this和this）線程中解決它，它在我自己的虛擬機上爲我工作，但在雲計算機數據表中無效。我爲他們做了同樣的過程。但云中的錯誤與之前在虛擬機中的錯誤相同。在雲上應該做些什麼來解決它？

你在這些鏈接的線程中做了完整的「git clone」步驟嗎？你是否需要實際修改jblas？如果不是的話，你應該把它們從maven中心使用--packages org.jblas:jblas:1.2.4，而不用git clone或mvn install;以下的罰款對我來說是新的Dataproc集羣：

此外，如果您需要通過Dataproc的作業提交API提交要求「套餐」的工作，然後因爲--packages是在不同的火花發射實際上是語法糖腳本而不是Spark作業的屬性，則需要使用等效的spark.jars.packages，而不是在這種情況下，如explained in this StackOverflow answer。
