On behalf of the NumPy team I'm pleased to announce the release of NumPy 1.16.1. This release fixes bugs reported against the 1.16.0 release, and also backports several enhancements from master that seem appropriate for a release series that is the last to support Python 2.7. The supported Python versions are 2.7 and 3.5-3.7. The wheels on PyPI are linked with OpenBLAS v0.3.4+, which should fix the known threading issues found in previous OpenBLAS versions. Downstream developers building this release should use Cython >= 0.29.2 and, if using OpenBLAS, OpenBLAS > v0.3.4.
If you are installing using pip, you may encounter a problem with older installed versions of NumPy that pip did not delete becoming mixed with the current version, resulting in an ImportError. That problem is particularly common on Debian derived distributions due to a modified pip. The fix is to make sure all previous NumPy versions installed by pip have been removed. See #12736 https://github.com/numpy/numpy/issues/12736 for discussion of the issue. Note that previously this problem resulted in an AttributeError.
Wheels for this release can be downloaded from PyPI https://pypi.org/project/numpy/1.16.1/, source archives and release notes are available from Github https://github.com/numpy/numpy/releases/tag/v1.16.1.
