Will Jones commented on ARROW-13657:
------------------------------------
This is not a bug; Flight is not shipped in all versions of the wheel. You will
also get an import error if you attempt to import pyarrow.gandiva, which is
also an optional feature. It is turned off for arm64 MacOS here:
[https://github.com/apache/arrow/blob/8f0ddc785dd72e950b570f3bc380deb15c124c45/dev/tasks/python-wheels/github.osx.arm64.yml#L26]
The Conda-packaged pyarrow has Flight and other optional features enabled. As a
workaround, you can either install through conda, or built a custom wheel with
the components you want.
If you think this should be added to the wheel, you are welcome to open a
feature request/or re-classify this as one.
