Hi,

The January meeting is going to be on Thursday the 27th at 7 p.m. at Carrboro Creative Coworking.  At the moment we've don't have a speaker lined up so if you'd like to present this is your chance! 

Please send me an email if you'd like to give a talk or a lightning talk.

Best,

Brad

I'll give a lightning talk on pdb just to make sure we have some newbie 
content at the meeting.

You should really look at either epdb, or ipdb instead.  Tab
completion alone make it a worthwhile exercise.  I challenge you to do
your lightning talk on either of those instead.

As a newbie,

I would not want to forgo any lightning talk Chris proposes. Including
spreading peanut butter on toast with my left hand instead of my right.
 (sorry, was that snarky?)

What would be REALLY sweet if Joseph would follow Chris's talk on pdb (which
coincidentally is what I was brushing up on last night...)

with his own take on epdb or ipdb.  Which I know nothing about but clearly
should.

That way we would have two lightning talks!

Cheers

BTW, just to be clear to bioinformaticians, the pdb I'm referring to is 
the Python batteries-included debugger, not Protein Data Bank (which has 
a huge Python user-base itself).

Reminder: meeting in two days: http://trizpug.org/Members/bac/jan-11-mtg

When: Thursday January 27, 7pm

Where: Carrboro Creative Coworking, 205 Lloyd Street, Suite 101, Carrboro.

What: This meeting promises mostly lightning talks about Python 
debugging. Chris Calloway will talk briefly about pdb for newbies and 
Joseph Tate will represent epdb. As usual, bring your own lightning talk 
about any observation you've made about any Python topic. There's plenty 
of free parking at CCC and the after-meeting will continue around the 
corner at Milltown.

Message-ID: <Pine.LNX.4.64.1101260920350.26551@wm7d.net>

python-2.6.5
numpy-1.5.1

I build and install numpy without errors, but when I do 
"import numpy" I get

ImportError: /usr/atlas/lib/liblapack.so: undefined symbol __powidf2

where __powidf2 is defined in /usr/lib/libgcc_s.so

I've installed numpy on several machines, sometimes it works 
and sometimes it doesn't. When it doesn't, I get the above 
error. I have no idea why sometimes it works and sometimes 
it doesn't. Presumably somewhere in the installed numpy (in 
/usr/lib/python2.6/site-packages/numpy) there has to be info 
about -lgcc_s but I haven't found it.

Any ideas?

thanks Joe

hmm. I've solved this for the moment, by recompiling 
liblapack.so.

If anyone knows how I could have added an extra library for 
numpy to search, I'd be glad.

THanks Joe

It's about the way lapack is built on the machines where it fails. It 
sounds like you need a shared (not static) lapack built with -fPIC.

On the machines where it fails, see if your *nix distribution has an 
update for lapack. Make sure there are no stray .a lapack libs left 
around after the update.

You may end up having to build lapack yourself if updates don't work.

You can also use alternate linear algebra libraries to lapack, like blas 
or atlas or mkl, with numpy.

Your linear algebra libraries will need to have been built with the same 
C and Fortran compilers as numpy. See:

http://docs.scipy.org/doc/numpy/user/install.html#how-to-check-the-abi-of-blas-lapack-atlas

Finally, you can also install numpy with no linear algebra libraries. 
Numpy will just run a lot slower for some thing. But it will work. You 
can do this with:

BLAS=None LAPACK=None ATLAS=None python setup.py build

If fiddling with configuration isn't how you like to spend time, you 
might consider a pre-built numpy environment like EPD:

http://www.enthought.com/products/epd.php

or Sage:

http://www.sagemath.org/download.html

or PythonXY

I take it that you can't handle it after the fact, by 
passing another library to the python build?

I've built everything with the same scripts/configure files. 
On two machines, numpy built fine, then later I upgraded 
numpy, and it failed. I then tried to re-build/install the 
first numpy and this failed too. No obvious change in the 
machine.

I've just done that and am trying it out on a few machines. 
It's worked on one so far.

I've built lapack from ATLAS, supposedly with the full 
lapack build option. I get no errors but lots of the lapack 
routines aren't defined in the output libs. So I'm back to 
building from lapack.

hmm yes. It isn't a lot of fun. The Makefiles add the same 
.o file twice in places. I'd assumed the linker would handle 
it, putting in only one copy, but two are in the lib.

maybe after I've figured this all out, I should go do all 
the other algebra libraries, to make sure I've got it all 
down.

I found that out a while ago. It wasn't a big surprise after 
the fact.

didn't know that. At the moment I'd be happy if they ran at 
all.

I would love to learn how to configure things like this, so 
I can handle problems by reading the files. Where should I 
have looked to see that I can turn off BLAS, LAPACK and 
ATLAS, like you've shown above?

> you might consider a pre-built numpy environment like EPD:

I looked for prebuilts a couple of years ago, when I first 
started doing this, but didn't find any. I'd prefer to 
figure out the problem. Getting a prebuilt binary is 
admitting defeat. Still I'll go have a look at these sites. 
I must be able to learn something here.

one problem I didn't realise is that `python setup.py clean` 
leaves files left over from when I was using ATLAS eg 
lapack_lite.so, This the undefined references, and gets 
installed when I run `python setup.py install`

Sorry I won't be able to make the meeting this evening, but you might also
consider ipdb as a debugger.

http://pypi.python.org/pypi/ipdb

The biggest things I like about ipdb (differerences from pdb):
1) colored syntax
2) tab completion
3 paging through matching methods in tab completion if there is a large
number
4) pinfo - shows you the source code for, and information about a method
(type,file,base class,argspec)

ipython is also a good choice for an interactive python shell - it has some
extras over the python shell.
ipdb requires ipython.

In case ya'll didn't know. I'm probably going to submit a proposal for 
my new pet project, crushinator (a more generic, front-end-friendly 
skeleton maker framework to replace PasteScript). I'll let everybody 
know if I get in :)

Hello Front Range Pythoneers!

On behalf of the Python Software Foundation?s sponsored sprint group, I
wanted to drop your group a quick note introducing us. If you?re already
familiar with our sponsored sprints, you?ll be happy to know we made a
few changes to help both sprint groups and Python even more.

The PSF recently set aside funding to be distributed to groups who spend
time contributing to the Python ecosystem, often in the form of
development sprints. Our goal is to help you help Python, so whether
it?s buying meals or renting meeting space for your all-day hackathon,
we have a budget set aside to reimburse your expenses up to $300 USD (up
from $250).


     If your goal is to make the Python world a better place, and you
     work on the problems facing Python today, we want to help you. We?re
     looking for groups of hackers that spend their time fixing and
     expanding the wide variety of Python interpreters, libraries, tools,
     and anything else affecting the community.


     We?re also looking for groups who want to help and get started but
     don?t have the resources to get together. Whether your group is
     separated by a train ride or lacking a shared space, we want to help
     you. On-boarding new contributors to open source Python projects is
     an especially important area that we?d like to work with.


     This means if you have a Python project and you want to sprint -- we
     want to help you.

Some sprints we?ve sponsored include the porting of Genshi to Python 3,
improvements to packaging (Distribute/distutils), and most recently, the
PyPy winter sprint in Switzerland.

If your group is interested in hosting a sprint, check out the full
details of our call for applications at
http://www.pythonsprints.com/cfa/and contact us at sprints at python.org
<mailto:sprints at python.org>.

Thanks for your time, and happy sprinting!

Also, let me know if any of you are interested in sprinting with me, one 
of the data points in the proposal is how many people are planning to 
attend.

Thanks,
