Debian packages of scipy and f2py
by José Fonseca Oct. 3, 2003

Oct. 3, 2003

I've make Debian packages of scipy and f2py. They are available from my apt-get repository at: http://jrfonseca.dyndns.org/debian/ I referred to Joe Reinhardt's packages http://people.debian.org/~jmr/ but have done these packages from scratch. These come for all python versions in debian unstable (2.1, 2.2 and 2.3). I've run the standard tests successfully but I'd appreciate that problems with these packages to be reported to me [privately] as I'd like to have these on Debian proper at some time. One tricky issue I'd like to address with the scipy and f2py maintainers is the the scipy_distutils. Both scipy and f2py attempt to install to /usr/lib/python*/site-packages/scipy_distutils and at least on Debian this is not admissible so the packages conflict with each other and are mutually exclusive. This is particularly even more annoying for me, since for building scipy f2py is needed, so I need to install and uninstall them as a maniac. Is there any solution that allow both these packages to happily co-exist in a tree without overlapping? Enjoy, José Fonseca PS: Please CC'me on any reply as I'm not subscribed to all these lists.

Blitz++, NumArray...
by Fernando Perez Aug. 22, 2003

Aug. 22, 2003

Hi all, as some of you know, I'm a big fan of weave.inline() for the ease of development it offers. Essentially C++ becomes a scripting part of python, with only the occasional recompile overhead (but this is transparent to the users). inline() makes heavy use of the blitz++ library, to represent numpy arrays as blitz arrays and therefore index them as Arr(i,j,k...). This seems to me like a very sound decision, as the blitz library was specifically written to provide simultaneously fortran-like performance with high-level object orientation. With this in mind, I have a few questions: - Is there anything in Numarray's design which prevents this same trick from being used? The core of getting a Numpy array into a blitz one is simply a call to: // Convert a Numpy array to a blitz one, using the original's data (no copy) template<class T, int N> static blitz::Array<T,N> py_to_blitz(PyArrayObject *arr_obj) { blitz::TinyVector<int,N> shape(0); blitz::TinyVector<int,N> strides(0); for (int i=0;i<N;i++) { shape[i] = arr_obj->dimensions[i]; strides[i] = arr_obj->strides[i]/sizeof(T); } return blitz::Array<T,N>((T*) arr_obj->data,shape,strides, blitz::neverDeleteData); } I would not be surprised if something much like this would work for Numarrays, but I'd like to know for sure. - If the above is indeed possible for Numarray, do you guys feel that blitz should be considered an integral part of python's low-level arsenal, or not? I view its advantages especially in the field of an extremely clean, simple syntax (compared to the low-level Numpy API, I'm not familiar with Numarray yet). I've seen examples where a numpy algorithm can be recoded using blitz in a _far_ smaller amount of code, and with performance gains to boot (in some cases, not all). Please note that I am NOT second-guessing any of the design decisions made by the Numarray crowd. I just want to clarify if it's possible to have a C++ API which gives access to numarray with the simplest, highest-level syntax and behavior which is reasonable. This is important for teams where not everyone is an expert on C pointer manipulation details, but they may be perfectly ok with writing loops over things which can be indexed as A(i,j,k). - If any of this seems worthy of more detailed discussion, I told Eric Jones that I'd be happy to coordinate something along these lines at Scipy'03. If there's time in the schedule I'd be glad to do it officially, otherwise we can just try to keep it in mind for a lunch/dinner meeting. Documenting a 'Best Practices for low-level numerical work in python' would probably be a beneficial thing to do for the community. Right now there are so many options that I'm sure I'm not the only one to feel a bit confused. - If Blitz++ is indeed deemed a worthy piece of this puzzle, I wonder if we could contact some of its developers to bring them into this discussion. I worry a bit that activity on its mailing lists seems rather slow, but I noticed that an apparently central guy, Julian C. Cummings, is at CACR/Caltech. Perhaps he could stop by and let us know what the future for blitz looks like. I can fire off an email to him if there is interest in the blitz thing. Anyway, I'm just trying to 'pre-soak' a few ideas for discussion at scipy'03 on these topics. Best regards, Fernando.

CVS trouble at scipy?
by Fernando Perez Aug. 22, 2003

Aug. 22, 2003

Hi all, today I'm seeing some problems when I commit code to CVS. The commits seem to go through fine, but at the end something email-related is tripping. Here's the error that I see: ************************************************************************* cvs -f commit -l -m 'Clean up code for avoiding auto-call triggering on [] access.'

New release of Python 2.2.3 (Enthought Edition) available
by David C. Morrill Aug. 21, 2003

Aug. 21, 2003

Just thought we would give everyone a head's up that a new release of Python 2.2.3 (Enthought Edition) is available for download at: http://www.enthought.com The main changes in this release are improvements to the chaco and kiva packages. In particular, this is the first release of chaco that uses the new kiva "agg" (Anti_Grain) driver that supports: - Faster rendering speeds. - Anti-aliasing of lines and text. - Alpha channel support for colors (i.e. transparency). - Improved chaco and traits documentation formatting (generated using the new pydoh package). Enjoy! The Python guys at enthought

Dear experts, When I redirect the output pf xplt.plot to an eps file via xplt.eps the ylabel disappears in the eps file. A small example is illustrating this behaviour. Any idea ? Thanks in advance. Nils from scipy import * from scipy.xplt import * import gui_thread x = arange(0,pi,0.1) xplt.plot(x,sin(x),'dot',x,sin(x),'dash''r') xplt.xlabel('x') xplt.ylabel('y') xplt.eps('somefile')

Aug. 18, 2003

Dear experts: � I am getting very strange error with SciPy-0.2.0-alpha. All multiplication involving array (array*scalar) coerces fractions into 0's.

Re: [Scipy-chaco] ANN: Job posting -- developer position available

Hi Eric, > Ideal candidates will also demonstrate the following skills: > - Use of the wxPython user interface library > - Experience with Geophysics applications > - Experience in the fields of statistics, linear algebra and > calculus How much closer can you get ;-) Yes, I am a geotechnical engineer, yes I did work for GeoDelft (*the* company for geophysics in Holland and developers of the widly used MSerie (settlement, stability, foundations, groundwaterflow etc. etc.)), yes I have Python and 3+ years of programming experience (mostly Delphi and C++).. and yes.. uhm.. I do write English :-) And most of all; my current project (eating up my spare time) http://pyciv.sourceforge.net is a 'geophysical' project. I never thought anyone else would think of writing a geophysical tool with Python. But then... No.. I do not live anywhere near Austin.. Why do these things only happen in the USA :-) Good luck with the candidates, Rob ps. I realy hope your application will be open source. It is about time we get some good open source engineering tools. pps. Thanks for chaco and scipy. I use them in pyciv and they make calculations easy and graphical output of the results look very smooth indeed.

[Q] MLab module (in quadpack.py)??
by Anderi Smiranov Aug. 5, 2003

Aug. 5, 2003

hi i've built SciPy, SciPy-0.2.0_alpha_200.4161_src.tar.gz, Python 2.2.2, Numeric 23. This is great stuff! one question though: in scipy/Lib/integrate/quadpack.py i've found the line: import MLab besides the fact it breaks the import of quadpack: what is that? Some interface to MatLab from Python? Regards, Andrei Smirnov
