Jongbin Park created ARROW-11450: ------------------------------------ Summary: [Python] pyarrow<3 incompatible with numpy>=1.20.0 Key: ARROW-11450 URL: https://issues.apache.org/jira/browse/ARROW-11450 Project: Apache Arrow Issue Type: Bug Environment: python>=3.7 Debian 5.7 x86_64 Reporter: Jongbin Park
pyarrow 1.0 and 2.0 is not compatible with numpy 1.20.0 Running the following command would fail: {{pa.array(np.arange(10))}} with error {{pyarrow.lib.ArrowTypeError: Did not pass numpy.dtype object}} Numpy release note [[link|[https://numpy.org/doc/1.20/release/1.20.0-notes.html#compatibility-notes]]] mentions about the np.dtype related compatibility breaks. Also there is a C API change, which implies numpy dependency constraints should be tighter (whether <=1.20 or >1.20) depending on the compiled numpy version. -- This message was sent by Atlassian Jira (v8.3.4#803005)
