Diego Argueta created ARROW-4457: ------------------------------------ Summary: [Python] Cannot create Decimal128 array using integers Key: ARROW-4457 URL: https://issues.apache.org/jira/browse/ARROW-4457 Project: Apache Arrow Issue Type: Bug Affects Versions: 0.12.0, 0.11.1, 0.11.0 Environment: Python: 2.7.15 and 3.7.2 pyarrow: tested on 0.11.0, 0.11.1, 0.12.0 Reporter: Diego Argueta
There appears to have been a regression introduced in 0.11.0 such that we can no longer create a {{Decimal128}} array using integers. To reproduce: {code:python} import pyarrow column = pyarrow.decimal128(16, 4) array = pyarrow.array([1], column) {code} Expected result: Behavior same as 0.10.0 and earlier; a {{Decimal128}} array would be created with no problems. Actual result: an exception is thrown. {code} Traceback (most recent call last): File "<stdin>", line 1, in <module> File "pyarrow/array.pxi", line 175, in pyarrow.lib.array return _sequence_to_array(obj, mask, size, type, pool, from_pandas) File "pyarrow/array.pxi", line 36, in pyarrow.lib._sequence_to_array check_status(ConvertPySequence(sequence, mask, options, &out)) File "pyarrow/error.pxi", line 81, in pyarrow.lib.check_status raise ArrowInvalid(message) ArrowInvalid: Could not convert 1 with type int: converting to Decimal128 Could not convert 1 with type int: converting to Decimal128 {code} The crash doesn't occur if we use a {{decimal.Decimal}} object instead. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
