[Numpy-discussion] Status of NumPy and Python 3.3

2012-07-26 Thread Travis Oliphant
Hey all, I'm wondering who has tried to make NumPy work with Python 3.3. The Unicode handling was significantly improved in Python 3.3 and the array-scalar code (which assumed a certain structure for UnicodeObjects) is not working now. It would be nice to get 1.7.0 working with Python 3.3

[Numpy-discussion] Bug in numpy.mean() revisited

2012-07-26 Thread Tom Aldcroft
There was a thread in January discussing the non-obvious behavior of numpy.mean() for large arrays of float32 values [1]. This issue is nicely discussed at the end of the numpy.mean() documentation [2] with an example: >>> a = np.zeros((2, 512*512), dtype=np.float32) >>> a[0, :] = 1.0 >>> a[1, :]
