[Numpy-discussion] dimension along axis?

appear in different position so it's inconvenient to identify them. Is there anyway to get dimension along axis? (In this case should be axis0) -- Cheers, Grissiom ___ Numpy-discussion mailing list Numpy-discussion@scipy.org http://mail.scipy.org/m

Re: [Numpy-discussion] DVCS at PyCon

use git for my own project and enjoy working with it. You may find some useful documentation here: http://git-scm.com/ and a tutorial: http://www.kernel.org/pub/software/scm/git/docs/gittutorial.html What really lacks is a little bit learning and using. -- Cheers, Grissiom ___

Re: [Numpy-discussion] using assertEqual in unittest to test two np.ndarray?

== So I have to dir it to see is there any other useful functions. It will be perfect to document package method like assert_equal here. Thanks very much~;) -- Cheers, Grissiom ___ Numpy-discussion mailing list Numpy-discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion

[Numpy-discussion] using assertEqual in unittest to test two np.ndarray?

Use a.any() or a.all() -- Ran 2 tests in 0.003s FAILED (errors=1) I know I should use array_equal to test two arrays but it will be more convenient to implement it as __eq__. Any hints? Thanks in advance.

[Numpy-discussion] linalg.norm along axis?

Hi all, Is there any possibility to calculate norm along axis? For example: a = np.array(( (3,4), (6,8))) And I want to get: array([5.0, 10.0]) I currently use a for loop to achieve this, Is there any more elegant way to do this? -- Cheers, Grissiom

Re: [Numpy-discussion] Failing to build numpy properly on Ubuntu Hardy

ve encountered with such problem before. My solution is recompile the problem package(maybe atlas in your case) with -ff2c option passed to gfortran. -- Cheers, Grissiom ___ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion

Hi all, Nice to neet you all. I am a newbie in numpy. Is there any function that could unitize a array? Thanks in advance. -- Cheers, Grissiom ___ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo
