Re: [Numpy-discussion] how much does binary size matter?

Hi, We understand that it can be burden, of course a larger binary is bad but that bad usually also comes with good, like better performance or more features. How much of a burden is it and where is the line between I need twice as long to download it which is just annoying and I cannot use it any

[Numpy-discussion] proposal: smaller representation of string arrays

2017-04-20 Thread Julian Taylor
Hello, As you probably know numpy does not deal well with strings in Python3. The np.string type is actually zero terminated bytes and not a string. In Python2 this happened to work out as it treats bytes and strings the same way. But in Python3 this type is pretty hard to work with as each time yo

[Numpy-discussion] testing needed for f2py with char/string arrays

hi, we need to deprecate the NPY_CHAR typenumber [0] in order to enable us to add new core dtypes without adding ugly hacks to our ABI. Technically the typenumber was deprecated way back in 1.6 when it accidentally broke our ABI. But due to lack of time f2py never got updated to actually follow thr

hi, It has been very very long overdue but we finally have an attempt of making our text io functions actually use text IO instead of bytes IO. This means genfromtxt, loadtxt, fromregex and savetxt should support unicode input files of any python supported encoding and universal newlines. This is t

I have two ideas under one big important topic: make numpy python3 compatible. The first fits pretty well with the grant size and nobody wants to do it for free: - fix our text IO functions under python3 and support multiple encodings, not only latin1. Reasonably simple to do, slap encoding argume
