bug#25834: [PATCH] Update scipy stack.


From: Thomas Danckaert
Subject: bug#25834: [PATCH] Update scipy stack.
Date: Mon, 27 Feb 2017 10:54:36 +0100 (CET)

Hi,

here's a new and improved patch series, on top of the python-tests branch. It also needs python-cycler, which is currently only in master (cherry-picked commit included here for convenience).

some comments:

1) matplotlib-documentation/numpy-documentation: I decided not to use “(inherits ...)” because

- it got messy for matplotlib, where I think the “python2-variant” of
   the base matplotlib package interfered when trying to
   (package-with-python2 matplotlib-documentation), and

 - all of the input fields need to be rewritten anyway (the
   documentation packages only need a number of native inputs).

2) Building the latex version of scipy's documentation now fails due to missing unicode characters and a lot of unescaped inline math formulas, which are upstream issues IMO (I'll submit an issue on their github page).

3)

+        (uri (string-append
+              "https://pypi.python.org/packages/ec/9c/";
+ "368086faa9c016efce5da3e0e13ba392c9db79e3ab740b763fe28620b18b/" + "backports.shutil_get_terminal_size-" version ".tar.gz"))

Is it possible to use 'pypi-uri' here?

I couldn't find a working pypi-uri, having tried all sorts of combinations of “backports.shutil-get-terminal-size” or “backports-shutil-get-terminal-size” (is there some sort of trick to find these? These simple urls are never listed on pypi, is my impression.).

4) I removed the patch related to the Matplotlib Tk backend, because it now seems to work just fine without it. But maybe I misunderstand the reason the patch was there... comments?

cheers,

Thomas

Subject: [PATCH 4/9] gnu: python-numpy: Update to 1.12.0.

* gnu/packages/python.scm (python-numpy): Update to 1.12.0.
  [source]: Use github instead of sourceforge.
  [native-inputs]: Add python-cython.

  To simplify the handling of dependency cycles (numpy documentation depends
  on matplotlib, which depends on numpy), we split out the documentation into
  a separate package:
  (python-numpy-bootstrap, python2-numpy-bootstrap): Remove variables.
  (python-numpy-documentation, python2-numpy-documentation): New variables.
