[Numpy-discussion] sum of array for masked area

Hi All, I just posted this on the SciPy forum but realised it might be more appropriate here? I have a separate text file for daily rainfall data that covers the whole country. I would like to calculate the monthly mean, min, max and the mean of the sum for one state. The mean, max and min are jus

[Numpy-discussion] numpy datetime64 NaT string conversion bug & patch

If you convert an array of strings to datetime64s and 'NaT' (or one of its variants) appears in the string, all subsequent values are rendered as NaT: (this is in 1.7.1 but the problem is present in current dev version as well) >>> import numpy as np >>> a = np.array(['2010', 'nat', '2030']) >>>

Re: [Numpy-discussion] Silencing NumPy output

Hi, After more investigation, I found that there already exist a way to suppress those message on posix system. So I reused it in the PR. That way, it was faster, but prevent change in that area. So there is less change of breaking other syste: https://github.com/numpy/numpy/pull/4081 But it re

Re: [Numpy-discussion] PyArray_BASE equivalent in python

First, sorry for not responding to your other replies, there was a jam in Thunderbird and I did not receive your answers. The bits() seem to stay alive after deleting the image: from PySide import QtGui image = QtGui.QImage('/home/peter/code/pyTools/sandbox/images/faceDemo.jpg') a = image.bits()
