Jacek Pliszka commented on ARROW-3329: -------------------------------------- I did start from fresh git clone. Thank you for help anyway. Good docker file would be great. What do we do with Python tests? For me the most effective would be to add them in 0.17.1, alternative is to write them blindly and see Jenkins errors or to debug the above which would take most time but I will correct instructions too and maybe prepare docker file for Fedora. > [Python] Error casting decimal(38, 4) to int64 > ---------------------------------------------- > > Key: ARROW-3329 > URL: https://issues.apache.org/jira/browse/ARROW-3329 > Project: Apache Arrow > Issue Type: Bug > Components: Python > Environment: Python version : 3.6.5 > Pyarrow version : 0.10.0 > Reporter: Kavita Sheth > Assignee: Jacek Pliszka > Priority: Major > Labels: pull-request-available > Fix For: 1.0.0 > > Time Spent: 7h 20m > Remaining Estimate: 0h > > Git issue LInk : https://github.com/apache/arrow/issues/2627 > I want to cast pyarrow table column from decimal(38,4) to int64. > col.cast(pa.int64()) > Error: > File "pyarrow/table.pxi", line 443, in pyarrow.lib.Column.cast > File "pyarrow/error.pxi", line 89, in pyarrow.lib.check_status > pyarrow.lib.ArrowNotImplementedError: No cast implemented from decimal(38, > 4) to int64 > Python version : 3.6.5 > Pyarrow version : 0.10.0 > is it not implemented yet or I am not using it correctly?
