Github user WeichenXu123 commented on the issue:
https://github.com/apache/spark/pull/18797
Strange thing, the code failed this `require` at
https://github.com/scalanlp/breeze/blob/master/math/src/main/scala/breeze/optimize/StrongWolfe.scala#L73
in the three case:
org.apache.spark.ml.regression.AFTSurvivalRegressionSuite.should support
all NumericType labels, and not support other types
org.apache.spark.ml.regression.AFTSurvivalRegressionSuite.should support
all NumericType censors, and not support other types
org.apache.spark.mllib.optimization.LBFGSSuite.The convergence criteria
should work as we expect
@srowen @sethah Do you know the reason ? The require is almost impossible
to fail. Is there some bug in the three testcases?
