NumPy 1.14.1 Release Notes¶
This is a bugfix release for some problems reported following the 1.14.0 release. The major problems fixed are the following.
Problems with the new array printing, particularly the printing of complex values, Please report any additional problems that may turn up.
np.einsumdue to the new
optimized=Truedefault. Some fixes for optimization have been applied and
optimize=Falseis now the default.
The sort order in
axis=<some-number>will now always be lexicographic in the subarray elements. In previous NumPy versions there was an optimization that could result in sorting the subarrays as unsigned byte strings.
The change in 1.14.0 that multi-field indexing of structured arrays returns a view instead of a copy has been reverted but remains on track for NumPy 1.15. Affected users should read the 1.14.1 Numpy User Guide section “basics/structured arrays/accessing multiple fields” for advice on how to manage this transition.
The Python versions supported in this release are 2.7 and 3.4 - 3.6. The Python 3.6 wheels available from PIP are built with Python 3.6.2 and should be compatible with all previous versions of Python 3.6. The source releases were cythonized with Cython 0.26.1, which is known to not support the upcoming Python 3.7 release. People who wish to run Python 3.7 should check out the NumPy repo and try building with the, as yet, unreleased master branch of Cython.
A total of 14 people contributed to this release. People with a “+” by their names contributed a patch for the first time.
