SpePy Installation problem

Hi,
I was recompiling the C extension files from the SfePy and to the end of the process I have got the following error messages:
build_src: building npy-pkg config files : 'gcc' is not recognized as an internal or external command, operable program or batch file.
Building msvcr library: "c:\Python27\libs\libmsvcr90.a" (from C:\Windows\winsxs\x86_microsoft.vc90.crt_1fc**a long number string**\msvcr90.dll)
error: [Error 2] The system cannot find the file specified

I have just read that mingw is not part of the package anymore. Can this be a part of the problem? 

The shell command is as follows: python setup.py build_ext --inplace --compiler=mingw32

I am using Windows 7 and Python(x,y) version 2.7.9 

Can anyone here give me a start point as to what might be causing these two errors? If mingw32 is the problem what compiler option should I use?

Thanks in advance.
Regards,
Berat

Installation dilemma

Hi,

On my PC (64 bit Windows 7 SP1) I have Python 2.7.8 installed (which I have in my PATH btw, so whenever I call "python" from the windows command prompt it calls python 2.7.8 and I use pywikibot sometimes which depends on this installation of python) and I have downloaded Python(x,y) 2.7.9 and whenever I run the installer I receive the message:

Python 2.7 is already installed on your computer. 
It is recommended to uninstall it before installing Python(x,yz).
Do you want to install Python(x,y) anyway?

I have minimal technologic experience so I felt it was important for me to ask what happens if I click "Yes", can I expect big problems with my existing Python 2.7.8 installation? 

Thanks for your time,
Brenton

Google Summer of Code and NumFOCUS

Hi,

NumFOCUS has promotes and supports the ongoing research and development of
open-source computing tools including Python(X,Y).

This year NumFOCUS want to try be a Google Summer of Code
"umbrella" mentoring organization,

    Umbrella organizations are mentoring organizations accepted into the Google
    Summer of Code program that have other open source organizations working
    "under" them. Sometime organizations that work very closely or have very
    similar goals or communities may get put together under an "umbrella."
    Google stills expects all organizations under the umbrella, whether accepted
    into the program under their title or not, to adhere to all the rules and
    regulations of the program.

    From https://www.google-melange.com/gsoc/document/show/gsoc_program/google/gsoc2015/help_page#umbrella_organization

To help promote and support Python(X,Y).

We encourage Python(X,Y) to apply to Google Summer of Code under your own title
and will be very happy if you can also do with us.
If you are interested, please check https://github.com/swcarpentry/gsoc2015
and https://github.com/swcarpentry/gsoc2015/blob/master/CONTRIBUTING.md.

If you have any question, please email me directly.

Thanks in advance,
Raniere

[python(x,y)] ANN: SciPy Latin América 2015 - Call for Proposals

*Call for Proposals*

*SciPy Latin América 2015*, the third annual Scientific Computing with
Python Conference, will be held this *May 20-22* in *Posadas, Misiones,
Argentina*.

SciPy is a community dedicated to the advancement of scientific computing
through open source Python software for mathematics, science, and
engineering. The annual SciPy Conferences allows participants from
academic, commercial, and governmental organizations to showcase their
latest projects, learn from skilled users and developers, and collaborate
on code development.

*Proposals are now being accepted for SciPy Latin América 2015*.

Presentation content can be at a novice, intermediate or advanced level.
Talks will run 30-40 min and hands-on tutorials will run 100-120 min. We
also receive proposal for posters. For more information about the different
types of proposal, see below the "*Different types of Communication*"
section.

*How to Submit?*

   1. Register for an account on http://conf.scipyla.org/user/register
   2. Submit your proposal at http://conf.scipyla.org/activity/propose

*Important Dates*

   - *April 6th*: Talks, poster, tutorial submission deadline.
   - *April 20th*: Notification Talks / Posters / Tutorial accepted.
   - *May 20th-22nd*: SciPy Latin América 2015.

*Different types of Communication*

*Talks*: These are the traditional talk sessions given during the main
conference days. They're mostly 30 minutes long with 5 min for questions.
If you think you have a topic but aren't sure how to propose it, contact
our program committee and we'll work with you. We'd love to help you come
up with a great proposal.

*Tutorials*: We are looking for tutorials that can grow this community at
any level. We aim for tutorials that will advance Scientific Python,
advance this community, and shape the future. They're are 100-120 minutes
long, but if you think you need more than one slot, you can split the
content and submit two self-contained proposals.

*Posters*: The poster session provides a more interactive, attendee-driven
presentation than the speaker-driven conference talks. Poster presentations
have fostered extensive discussions on the topics, with many that have gone
on much longer than the actual "session" called for. The idea is to present
your topic on poster board and as attendees mingle through the rows, they
find your topic, read through what you've written, then strike up a
discussion on it. It's as simple as that. You could be doing Q&A in the
first minute of the session with a group of 10 people.

*Lightning Talks*: Want to give a talk, but do not have enough material for
a full talk? These talks are, at max, 5 minute talks done in quick
succession in the main hall. No need to fill the whole slot, though!

scipy.sparse.linalg.factorized

I have the Python(x,y)-2.7.9.0.exe installation of python(x,y). I want to use scipy.sparse.linalg.factorized to solve linear systems using Umfpack. Does the python(x,y) installation include the necessary Umfpack code? How can I tell that I'm getting Umfpack and not superLU when I call factorized?

ipython notebook server and pylab mode

I just installed python(x,y) on my windows 7 box and when I run the ipython notebook server I get a message in the command prompt window:

2015-01-02 02:49:00.497 [NotebookApp] WARNING | Starting all kernels in pylab mode is not recommended,
    and will be disabled in a future release.
    Please use the %matplotlib magic to enable matplotlib instead.
    pylab implies many imports, which can have confusing side effects
    and harm the reproducibility of your notebooks.

I have not yet changed any of the command line options or configuration files. They are exactly what Python(x,y)-2.7.9.0.exe installed.
The execute line is:

C:\Python27\Scripts\ipython.exe notebook --pylab=inline

Should I be concerned about this warning or just ignore it?

Python(x, y) 2.7.9.0 Released!

Hi All,


I'm happy to announce that Python(x, y) 2.7.9.0 is available for immediate download.from any of the mirrors. The full change log can be viewed here. Please post your comments and suggestions to the mailing list.

Work on the 64 bit & 3.x versions progresses slowly but surely. They will happen eventually :)

What's new in general:

  • The official Visual C++ for python 2.7 has replaced MinGW as the bundled compiler. Finally everyone can enjoy native python binary extenions for win32. MinGW is still available as an additional plugin.
  • Console2 has been replaced with ConsoleZ - a actively developed fork. Which adds split views and many other improvements.
  • Maintaining 2/3 code base is much easier with the inclusion of python-modernize. Also all backports have been updated and expanded with unittest2.
  • All packages updated to their latest versions (at the time) - IPython, GDAL, SciPy, ITK, VTK. sqlalchemy, Astropy, SWIG etc. 
  • User Local install support has been revived - it is still experimental though.
  • Numpy has been held back at 1.8.2 to avoid potential comparability issues.

New noteworthy packages:

  • cvxpy- A domain-specific language for modeling convex optimization problems in Python.
  • grin - Utility which searches directories of source code better than grep or find.
Have fun!

-Gabi Davar

status of this project?

Hello,
what's the current status of this project?

from
https://code.google.com/feeds/p/pythonxy/downloads/basic

I can see that we haven't had many updates this year.

Are users encouraged to move to Anaconda?

Regards,
Timmie
