[B! numpy] chorinskyのブックマーク

とにかく行列の掛け算さえできればいい！と思ってごちゃごちゃやってみた参考にさせてもらったサイト良いもの。悪いもの。機械学習序曲(仮) １つ目のサイトで味をしめたので、２つ目のサイトに乗ってたPythonのプログラムを実行してみた。 ERROR！なんか（かなり）簡単に言うとnumpyのバージョンが違うらしいということで自分なりに書き換えて見ました〜ただ書き換えただけのプログラムを載せるのは憚れるので変更点だけ！ from Numeric import * from LinearAlgebra import * ↓ from scipy import * from numpy import * A = init('A.dat', num) B = init('B.dat', num) ↓ A = init('A.dat', num) B = init('B.dat', num)

SciPy - Installation

Installations methods include: Distributions pip conda Package Manager Source Methods differ in ease of use, coverage, maintenance of old versions, system-wide versus local environment use, and control. With pip or Anaconda's conda, you can control the package versions for a specific project to prevent conflicts. Conda also controls non-Python packages, like MKL or HDF5. System package managers, l

A quick hack to use the MKL with numpy/scipy on Linux – Matthieu Brucher's blog

I’ve promised to make an update whenever I would find a solution to the probl em I had some months ago when I tried to use the latest MKL with numpy. Well, there was a simple hack that did the trick. It is far from being perfect, but at least, the tests pass now. So the only thing you have to do is to export the LD_PRELOAD variable:

NumPy/MKL vs Matlab performance

Further to the post I wrote on the MKL performance improvement on NumPy, I have tried to get some figures comparing it to Matlab. Here are some results. Any suggestion to improve the comparison is welcome. I will update it with the different values I do collect. Here is the Matlab script I used to compare the Python code : disp('Eig');tic;data=rand(500,500);eig(data);toc; disp('Svd');tic;data=rand

Installing Numpy 1.5 for Python 3 [Archive] - Ubuntu Forums

Hi, I'm trying to install Numpy for Python 3 and am hoping that someone here can give me a hand.
