It's also possible to work around the 3.6.1 problem with a small preprocessor hack. On my phone but there's a link in the bug report discussion. On Jul 6, 2017 6:10 AM, "Charles R Harris" wrote: > Hi All, > > I've delayed the NumPy 1.13.2 release hoping for Python

Re: [Numpy-discussion] record data previous to Numpy use

OK, you have two performance "issues" 1) memory use: IF yu need to read a file to build a numpy array, and dont know how big it is when you start, you need to accumulate the values first, and then make an array out of them. And numpy arrays are fixed size, so they can not efficiently accumulate

Thanks Rober for your effort - I'll have a look on it ... the goal is be guide in how to proceed (and to understand), and not to have a "ready-made solution" ... but I appreciate honnestly :-) Paul Le 2017-07-06 11:51, Robert Kern a écrit : > On Thu, Jul 6, 2017 at 1:49 AM,
