After some inspection, https://github.com/mars-project/mars/issues/2505#issue-1021662005 perhaps explain it, gradient based loop solution for logistic regression is inefficient for xorbits
.
Maybe we should use a different approach on the control flows, like for loop. For example, the method in this paper.
Describe the bug
LogisticRegression.fit
never stops with a bit larger data.To Reproduce
When
max_iter=1
everything works fineHowever, just increase
max_iter
to 100, the program seems never stop (at least after 1min, it's weird.)
