Uwe L. Korn commented on ARROW-1345: ------------------------------------ I think we have at the moment some assumptions on 64bit builds in the code. They are not explicit but we have definitely never tested with 32bit. > [Python] Conversion from nested NumPy arrays fails on integers other than > int64, float32 > ---------------------------------------------------------------------------------------- > > Key: ARROW-1345 > URL: https://issues.apache.org/jira/browse/ARROW-1345 > Project: Apache Arrow > Issue Type: Bug > Components: Python > Affects Versions: 0.8.0 > Reporter: Wes McKinney > Priority: Major > Fix For: 0.9.0 > > > The inferred types are the largest ones, and then later conversion fails on > any arrays with smaller types because only exact conversions are implemented > thus far -- This message was sent by Atlassian JIRA (v7.6.3#76005)
