Description
I'm working on getting support for arrow in vaex (out of core dataframe library for Python) in this PR:
https://github.com/maartenbreddels/vaex/pull/116
And I fixed length binary arrays for numpy (say dtype='S42') will be converted to a non-fixed length array. Trying to convert that back to numpy will fail, since there is no such conversion.
It makes more sense to convert dtype='S42', to an arrow array with pyarrow.binary(42) type. As I do in:
