[jira] [Commented] (ARROW-4024) [Python] Cython compilation error
on cython==0.27.3
[ https://issues.apache.org/jira/browse/ARROW-4024?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16722460#comment-16722460 ]
Uwe L. Korn commented on ARROW-4024:
------------------------------------
[~pcmoritz] Is there anything that keeps you on this Cython version? As Cython is a build-time but not a runtime dependency, I would close this bug as won't fix (maybe first ensure that we pin correctly).
