datetime.date support in NumPyPy
Is there any estimate on when NumPyPy will support datetime.date objects in arrays? Regards, Antti Mäkinen

Well, the object dtype is already supported in the default branch, so you can put datetime.date objects in arrays. If you were thinking of the np.datetime64 and np.timedelta64 dtypes, they aren't supported yet, and we're not planning on adding them in the immediate future unless there's a compelling use case.
Thanks for the answer! I don't know if I'm missing something, but initializing arrays with dtype=object seems to fail. I'm using PyPy 2.5.1 on OS X 10.10 and Numpy from the PyPy's Numpy fork. I'm assuming the "master [MAIN BRANCH]" is the same as the "default branch". Initializing the arrays fails like this:
import numpy numpy.zeros(2, dtype=object) Traceback (most recent call last): File "<stdin>", line 1, in <module> NotImplementedError: cannot create dtype with type 'object'
Numpy was installed like this: git clone https://bitbucket.org/pypy/numpy.git; cd numpy; pypy setup.py install

pypy-dev mailing list pypy-dev@python.org https://mail.python.org/mailman/listinfo/pypy-dev You will need a pypy from after the merge of the object-dtype2 branch (post-release-2.5.1), unfortunately we have no working macosx buildbots at the moment so you would have to translate it for yourself.
2.6.0 should be out in two weeks or so with the object dtype. Help with finding a functioning macosx buildbot would be appreciated Matti
Great news! I'll wait for the 2.6.0 release then :)
