Can anyone help me get rid of these warnings in Django please?

pkg_resources.ExtractionError: Can't extract file(s) to egg cache
The following error occurred while trying to extract file(s) to the Python egg
cache:
[Errno 13] Permission denied: '/home/interworx/.python-eggs'
The Python egg cache directory is currently set to:
/home/interworx/.python-eggs
Perhaps your account does not have write access to this directory? You can
change the cache directory by setting the PYTHON_EGG_CACHE environment
variable to point to an accessible directory.
I'm not sure if the "Module was already imported" error has to do with the "cannot extract PYTHON EGG" error.
In my WSGI I already have the following line os.environ['PYTHON_EGG_CACHE'] = rel('python-eggs') and I know for sure that works. Otherwise WSGI won't load my app. So I'm not sure what to do here.
Thanks!
When you get a message like "Perhaps your account does not have write access to this directory?" it's best to do a quick test. Try changing it to "/tmp" (which is writable by everyone) and see if things start working. If that fixes it, you can then identify a more appropriate directory and make sure that you (or the server) have write access to it.
Update: You are correct in choosing to tackle the earliest error message first. Here is a quick utility, Python Module Dump, that I wrote a few years ago for tracking down a mis-included module error. You might try inserting it at interesting points along your initialization code path and see if you can spot when the earlier import occurred.
There's a chance that your initial problem "Module was already imported" does in fact have to do with the permissions error you have going. Your best option would be to fix the permissions/ownership settings on the /home/interworx/.python-eggs directory (as stated by Peter Rowell above).
I came across this great little refresher on permissions today at the Google Code University. Wouldn't hurt to skim through this when you have some time: http://code.google.com/edu/tools101/linux/ownership_permissions.html
Just read the comments above here is my thoughts:
I think the problem is that the .wsgi file is not setting the environment variable in time. Can you please post your .wsgi file? Also, how are you grabbing the packages? Is it a script? Manually via pip?

I have a small python (2.7) script that works with several threads. One of the threads will read a global list and post an https post request for each one of the entries of this list.
For doing that I saw that the best way is to use python requests module. I have installed it with pip (no problem with that, it is placed in ...Python/2.7/site-packages/requests/...), but, when I import this module in my script, I get an error.
I have created another script with just one line (import requests) to reproduce the error, and I get this:

Am I doing something wrong? Didn't I installed the module in the proper way?
it seems that you're having two modules with the same name array.py
rename your local array.py module to something more unique to resolve this.
take a look at this answer for more info on how to handle this issue and here to learn more on how python import system works.
I'm using pyramid 1.5.1 and python 3.2, and I just added quite a bit of code and a couple libraries to my project.
On running development.ini, I'm getting the error below.
If I had to take a wild guess, I would say that this particular library (looks like Markupsafe?) isn't compatible with Python3...but the project page seems to indicate that it is. Problem is, I'm not calling this library directly, it's being used by another library that would be very difficult to replace.
I'm new to Python programming, and I was wondering what my options are here Or what the best way to debug is?

SyntaxError: invalid syntax
The MarkupSafe package uses syntax only supported by Python 3.3 and up. Python 3.2 is not supported anymore as of version 0.16.
The u'unicode' literal syntax was introduced in PEP 414 to make it easier to create library code that can support both Python 2 and 3.
Either upgrade to Python 3.3 (or 3.4 even), or downgrade MarkupSafe to 0.15, the last version to support Python 3.2.
I do see that Mako removes the MarkupSafe dependency when you are using Python 3.2; if nothing else depends on it is perhaps safe to remove the package altogether. The mako.filter source code certainly will fall back to a local implementation if the package is not installed.
I have a build script for one of my established Python applications that uses Pyinstaller. This script has been working fine for over a year. Then today, I added to one of the source files for this application the line
import scipy.stats
because I want to use scipy.stats.linregress. This now causes the build script to crash with a long error traceback (apparently going back through a sequence of modules that import each other) ending with

ImportError: No module named scipy.sparse.csgraph._validation
This is puzzling because the module located at C:\Python27\Lib\site-packages\scipy\sparse\csgraph_validation.py very much exists. Why did adding scipy to my build break it (importing numpy works just fine), could it be failing to find it?
Not entirely sure why, but including the following definition in my code after the import statement fixed it:

edit: the line that causes errors is a simple import from django.db:
from django.db import models
This whole setup is already running on some server that I dont have access to, so it seems to be nothing wrong with django app or scripts...
Any help would be appreciated cause I am running out of ideas how to solve this problem...
I dont know your performance and scalability requirements, despite that a softswitch have realtime requirements to run rtp stream and signalling. So is not a good solution run django applications under mod_python. Furthermore that is not the same as python interpreter directly, somethings does not work. You can check the mod_python issues here:
mod_python issues
I would advice you to split your python solution in a client/server architecture. The script running under mod_python will make queries to your Django application. That way you will get rid of the complexity in Freeswitch side, get scalable, improve performance and most probably get everything working OK.
I tried to use djangos i18n and therefor had to install gettext. Now I'm getting this awkward error any time I try to start my application:

The library locale.py is present and I can import it. Django 1.4 is running under Python 2.7.2+. Any Ideas?
I guess you have somewhere inside your project a folder locale with an __init__.py file in it.
Delete this file (you don't need it for translation to work) and you should be good to go.
