Zhuo Peng created ARROW-11458: --------------------------------- Summary: PyArrow 1.x and 2.x do not work with numpy 1.20 Key: ARROW-11458 URL: https://issues.apache.org/jira/browse/ARROW-11458 Project: Apache Arrow Issue Type: Bug Components: Python Affects Versions: 2.0.0, 1.0.1, 1.0.0 Reporter: Zhuo Peng
Numpy 1.20 was released on 1/30 and it is not compatible with libraries that built against numpy<1.16.6 which is the case for pyarrow 1.x and 2.x. However, pyarrow does not specify an upper bound for the numpy version [1]. ``` Python 3.7.9 (default, Oct 30 2020, 13:50:59) [GCC 10.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import pyarrow as pa >>> import numpy as np >>> np.__version__ '1.20.0' >>> pa.__version__ '2.0.0' >>> pa.array(np.arange(10)) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "pyarrow/array.pxi", line 292, in pyarrow.lib.array File "pyarrow/array.pxi", line 79, in pyarrow.lib._ndarray_to_array File "pyarrow/array.pxi", line 67, in pyarrow.lib._ndarray_to_type File "pyarrow/error.pxi", line 107, in pyarrow.lib.check_status pyarrow.lib.ArrowTypeError: Did not pass numpy.dtype object ``` [1] https://github.com/apache/arrow/blob/478286658055bb91737394c2065b92a7e92fb0c1/python/setup.py#L572 -- This message was sent by Atlassian Jira (v8.3.4#803005)
