我有以下数据帧，其中包含需要转换为Vectors的双精度数组，以便将其传递给ML算法。任何人都可以帮我这个吗？
fList: org.apache.spark.sql.DataFrame = [features: array<double>]
+--------------------------------------------------------------------------------+
|features |
+--------------------------------------------------------------------------------+
|[2.5046410000000003, 2.1487149999999997, 1.0884870000000002, 3.5877090000000003]|
|[0.9558040000000001, 0.9843780000000002, 0.545025, 0.9979860000000002] |
+--------------------------------------------------------------------------------+
预期产出： 应该看起来像这样。
fList: org.apache.spark.sql.DataFrame = [features: vector]
