I was trying to install a module for opencv and added an opencv.pth file to the folder beyond my sites.py file. I have since deleted it and no change.
When I try to run help('modules'), I get the following error:
Please wait a moment while I gather a
list of all available modules...

What gives?!
This happens because help('modules') imports all modules, which can result in a lot of unsentineled code being executed. There's nothing you can do short of reporting bugs in every single package that causes this (opencv in this case) and wait for them to fix it.

I am creating project on attendance system using QR Code scanning and I use Python to create it.
I used all needed libraries in the program
like, cv2, numpy, pybase64, pyzbar.
But I am getting this above Error in the Pyzbar.
I got solution for this issue. I was facing similar issue just installed Visual C++ 64 bit version on my computer and restarted. Choose between vcredist_x86.exe or vcredist_x64.exe based on your machine.

Problem resolved.
I found the following support request on SourceForge which refers to a need to use short format (8.3) path and filenames in pychecker.bat and not long format as is allowed in newer versions of Windows.
https://sourceforge.net/p/pychecker/support-requests/7/#96cb
I followed the instructions here: http://shon.github.io/2014/06/19/ui_testing_and_bdd.html about setting up Splinter with Behaving to run automated tests. I'm able to run a test successfully, but at the end of the test, it throws an error saying:
KeyError: 'browser'
and it won't continue testing any additional feature files. I'm pretty new to python and need some help in troubleshooting this.

Know anyone whats wrong?
I think this is caused by the template you are using. Perhaps it is outdated.
Check if your setup.py looks like this:
packages=find_packages('src'),
namespace_packages=['gomobiletheme'],
But you need an additional:
package_dir = {'': 'src'},
directive to get the buildout working again.
I am trying to run Pyramid with Jinja2 using new Python 2.7 runtime in threadsafe mode and GAE 1.6.0 pre-release SDK. I've made modifications to my app as outlined here, i.e. I've set runtime: python27, threadsafe: true in app.yaml and got rid of main() function. When I generate response by myself it works fine, but when I try to bring jinja2 into the equation, I get the following exception:

ImportError: Cannot re-init internal module __main__
I'd be happy if anybody could shed some light on what pyramid is trying to do under the hood. Judging by the latter stack trace it seems it's trying to resolve an asset, but why is it trying to reload __main__? I'm not even sure my problem is caused by pyramid or GAE.
Thanks for any insight on this issue.
I'm not familiar with pyramid, but the problem really does seem to be with this line:
config.include('pyramid_jinja2')
Whatever that config thing is, it seems to be doing some dynamic import magic.
Don't do that.
The app engine environment doesn't handle imports the way you would in normal python. Step through that line with a debugger and you'll wind up in the replacement version of the import system, which you'll soon see, only implements a small part of what real python does.
If possible, just use a normal import statement... Otherwise, you're going to have to dig into config.include and get it to play nice with the restricted importing features on GAE.
I managed to make it work using Pyramid 1.3's AssetResolver. First attempt is here. Just not sure what the lifetime/scope of the resolver should be in this case, I will figure it out later.
In pyramid_jinja2/__init__.py add the following code before _get_or_build_default_environment()
class VirtualModule(object):
def __init__(self,name):
import sys
sys.modules[name]=self
def __getattr__(self,name):
return globals()[name]
VirtualModule("__main__")
