Python Modules

[jawknee]

Hi all. I'd like to be able to use the python dateutils module, but I can't find it. Is there a place where some of these modules live? Is there a way to install them otherwise?

thanks,
-Johnny

Johnny,

Is there a particular function that isn't working for you? The following seems to work on both the shell and web cluster:

Code: Select all

#!/usr/bin/python
from datetime import *

NOW = datetime.now()
TODAY = date.today()
print NOW
print TODAY

-- Joe

Hey Joe - thanks for the reply...

Basically time zones and conversion to/from UTC / local time. I'm still fairly new to python, but the research I've done has indicated that either dateutils or pytz is required to do this well - I coded to dateutils.

I'm hoping to run some of the scripts in a cgi-bin context.

thanks,
-Johnny

My recommendation is to load the python modules from a local (relative to website) directory. A good guide on how to do so can be found at:
http://stackoverflow.com/questions/2792 ... m-a-folder

I haven't fully tested it, but if you have the right files, you should be able to import the missing modules from you own copies.

Joe - excellent, I'll definitely check that out.

thanks!

Joe - thanks again for the reply. I've been working on other aspects of my project but I finally got back to this. It turns out the dateutil module is so tiny I can easily include it in my local dir.

But not so the Python Image Library: PIL. For that I used your recommendation and that is working, but...

PIL requires a setup step that has to compile bits of C code. That's failing for me with:

$ python setup.py install
running install
error: invalid Python installation: unable to open /usr/include/python2.6/pyconfig.h (No such file or directory)

---
The /usr/include/python2.6/ dir is empty.

I'm guessing I'm stuck at this point (I don't have acces to a 2.4 linux machine or I'd attempt to cross compile).

If you have any idea how I can proceed, that's be great. In any case - thanks for the pointer on the path.

I do like a good puzzle! :-p Placing a properly-generated version of the pyconfig.h file did help move things along further, but the version of gcc on shell appears to possibly be too old to work. :-/

I'll see if I can hack at it a bit further this weekend.

My hero! I noted there is still nothing in /usr/include/python2.6/ on shell.sonic.net so I'm guessing you're working in a different context? In any case, this would be cool - be nice not to have to run home to update the links.

Joe - any further luck? Anything I can do to help?

Well, I managed to get it to work under Python 2.3.4:

1.) Download the latest PIL source package (http://effbot.org/media/downloads/PIL-1.1.7.tar.gz)
2.) Unpack it (tar xzf PIL-1.1.7.tar.gz)
3.) Attempt to perform an in-place build (from the extracted directory, run: python setup.py build_ext -i)
4.) Verify it works by running 'python selftest.py' from the same directory.
5.) Copy the subfolder in the build directory to a location of your choosing, than make sure python knows to load extensions from there.
6.) ???
7.) Profit!
