Hello everyone,<br><br>I am interested in porting SciPy/NumPy to Py3k. I've been working this past school year to port an existing code base to py3k for a research group on campus. A lot of the code relies on SciPy and NumPy but the scope of my project didn't let me work on porting either project, to my dismay. I'd love the opportunity to port a project I use heavily in my own code and gain a better understanding of how it works. <br>
<br>We are supposed to contact the group we would be working with, to flesh out the details of our application. I've looked at the application and the only thing I know I'll need significant help with is the Milestones portion. Of course, Any and all suggestions are welcome! <br>
</blockquote></div><div><br>Do you have a plan of attack?</div></div></blockquote></div></div><div><br> I do. I've done some looking through the
trunk svn, and I see three chunks to the project. the Distutils, NumPy
and SciPy. Distutils would be first on the list to be ported as the
other two won't install without it. for the most part I plan to stick to the outline in python's suggested porting method as it worked well for the Lab's codebase. (<a href="http://docs.python.org/3.0/whatsnew/3.0.html" target="_blank">http://docs.python.org/3.0/whatsnew/3.0.html</a>)<br>

</div></blockquote></div></div><div><br> Most of the code will require minor or stylistic changes here and
there. The two issues that require much more work are any __cmp__
methods and any questionable coding practices. I've found that the
things that 2to3 (the provided auto-converter) chokes on are things
that shouldn't have made it to production in the first place. Once
it's been run through 2to3, the bugs and errors that pop up don't seem
to follow much of a pattern and I expect much more work per bug or error in this auto-converted code.<br><br></div><div class="im"><div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<div class="gmail_quote"><div>I think if you can end the project with a report on your experience and a list of things that needed to be done that that would be helpful in itself.<br>
<br>Chuck </div></div></blockquote><div> </div></div></div><div>Thanks for the suggestions. I have one other question, are there unit tests available somwhere that I haven't seen? looking under the tests and testing folders in the source tree turned up a fairly lean set of tests. <br>
</div></div></blockquote></div></blockquote><div><br>Yes, test coverage certainly isn't where it should be and varies a lot among packages. We could probably use someone slogging away at the unromantic work of expanding the coverage if you know anyone who might be interested.<br>
<br>For distutils, David would probably be the best bet. The f2py translator is important for scipy and could probably use a looksie too. Other folks know more about scipy than I, so hopefully they will weigh in. I'm mostly a numpy guy so I was happy to see you included numpy in your list.<br>
<br>We can use all the help we can get.<br><br>Chuck<br><br></div></div><br>
