[jira] [Commented] (ARROW-6395) [pyarrow] Bug when using bool
arrays with stride greater than 1
[ https://issues.apache.org/jira/browse/ARROW-6395?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16920367#comment-16920367 ]
Joris Van den Bossche commented on ARROW-6395:
----------------------------------------------
Yes, this is already fixed on master. So closing as a duplicate. But thanks for the report anyway [~philjdf], and thanks for seeing the duplicate [~Igor Yastrebov]
The correct output I get on master:
{code}
In [3]: xs_sliced
Out[3]:
array([ True, False, True, True, True, False, False, True, True,
True, True])
In [4]: pa.array(xs_sliced, pa.bool_())
Out[4]:
<pyarrow.lib.BooleanArray object at 0x7fc6094dae08>
[
true,
false,
true,
true,
true,
false,
false,
true,
true,
true,
true
]
{code}
