ANN: Python Enthought Edition 1.0.0 Released
by Bryce Hendrix Aug. 2, 2006

Aug. 2, 2006

Enthought is pleased to announce the release of Python Enthought Edition Version 1.0.0 (http://code.enthought.com/enthon/) -- a python distribution for Windows. About Python Enthought Edition: ------------------------------- Python 2.4.3, Enthought Edition is a kitchen-sink-included Python distribution for Windows including the following packages out of the box: Numpy SciPy IPython Enthought Tool Suite wxPython PIL mingw MayaVi Scientific Python VTK and many more... More information is available about all Open Source code written and released by Enthought, Inc. at http://code.enthought.com 1.0.0 Release Notes ------------------------- A lot of work has gone into testing this release, and it is our most stable release to date, but there are a couple of caveats: * The generated documentation index entries are missing. The full text search does work and the table of contents is complete, so this feature will be pushed to version 1.1.0. * IPython may cause problems when starting the first time if a previous version of IPython was ran. If you see "WARNING: could not import user config", either follow the directions which follow the warning. * Some users are reporting that older matplotlibrc files are not compatible with the version of matplotlib installed with this release. Please refer to the matplotlib mailing list (http://sourceforge.net/mail/?group_id=80706) for further help. We are grateful to everyone who has helped test this release. If you'd like to contribute or report a bug, you can do so at https://svn.enthought.com/enthought.

a few problems and fixes
by Mathew Yeates Aug. 1, 2006

Aug. 1, 2006

Here are few problems I had with numpy and scipy 1) Compiling scipy on solaris requires running ld -G instead of gcc -shared. Apparently, gcc was not passing the correct args to my nongnu ld. I could not figure out how to alter setup.py to link using ld instead of gcc so I had to link by hand. 2) memmap has to be modified to remove "flush" on Windows. If calls to flush are allowed, Python (ActiveState) crashes at program exit. 3) savemat in scipy.io.mio had to be modified to remove type check since I am using the class memmap which derives from ndarray. In savemat a check is made that the object being save is an Array. Mathew

svn install failure on amd64

Hi people who know what's going on, I'm getting an install failure with the latest numpy from svn (revision 2940). This is on an amd64 machine running python 2.4.4c0. The build halts at: compile options: '-Ibuild/src.linux-x86_64-2.4/numpy/core/src -Inumpy/core/include -Ibuild/src.linux-x86_64-2.4/numpy/core -Inumpy/core/src -Inumpy/core/include -I/usr/include/python2.4 -c' gcc: numpy/core/src/multiarraymodule.c In file included from numpy/core/src/arrayobject.c:508, from numpy/core/src/multiarraymodule.c:64: numpy/core/src/arraytypes.inc.src: In function 'set_typeinfo': numpy/core/src/arraytypes.inc.src:2139: error: 'PyIntpArrType_Type' undeclared (first use in this function) numpy/core/src/arraytypes.inc.src:2139: error: (Each undeclared identifier is reported only once numpy/core/src/arraytypes.inc.src:2139: error: for each function it appears in.)

Release notes please; possible bugs
by Tom Loredo July 31, 2006

July 31, 2006

Hi folks, It is turning out to be much more of a headache moving from numpy-0.9.x to numpy-1.0b1 than it ever was moving from Numeric to numpy. Could someone please throw together some release notes (the scipy & sourceforge RN pages are blank) or a Wiki page warning what has to be changed? Here are some stumbling blocks I've come across: * Type names are all now lower case. I know this started happening late in 0.9.x, but I only know it by accident, via some email from Travis. This is just one example of the kind of change that really needs to be prominently noted somewhere. * .nonzero() now returns a 1-tuple with an array of indices, for a 1-d array. Before it returned an array of indices. * In the C API, ContiguousFromObject is now ContiguousFromAny. I am surprised that my libraries compile with no errors; I only get a runtime error. Shouldn't I be warned about this at compile-time? * mtrand still uses ContiguousFromObject in a few places; these give exceptions when you call, e.g., setstate. * rand, fft, ift are no longer in the numpy namespace. Is this a permanent change or a bug? There are probably other obstacles I'll come across, but this is what I encountered in code that ran perfectly with 0.9.6. After several hours of work it's still not running. -Tom Loredo ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/
