[pypy-dev] datetime.date support in NumPyPy

[Antti Mäkinen]

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

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.
