Open visio using python

I've a weird problem. I have coded a little python script to test if my idea would work (no worries, it's just for fun). I am trying to simply open visio, place a couple of objects and close it.
#Get visio application
import win32com.client as win32
visio = win32.gencache.EnsureDispatch('Visio.Application')
visio.Visible = True
And it worked, so I've left it as it is for this week and when I tested it again it gave me an error which didn't occur last time, and closed the application.

Does anybody know what happened, or what I'm doing wrong? I've tried to reverse an update that happened in the meantime. I've been looking if the win32com has been updated. Yet nothing did solve it.
I appreciate your assistance.

The awnser to this question has been posted here:
Why am I suddenly getting a no attribute 'CLSIDToPackageMap' error with win32com.client?
In short the problem can be solved by deleting the gen_py folder found in the temp folder. You can find the temp folder by searching for %temp% or go to c:\users<username>\appdata\local\temp (make sure to show hidden files).
Hope I was able to help.

Running code returns with "color must int or tuple"

I was running a tower defence game in the arcade module but after I press start, the game freezes up and returns with

TypeError: color must be int or tuple
And I'm not really sure why. It says my python packages are wrong so I uninstalled and reinstalled python multiple times too.
Can anyone help me?
Thanks in advance btw.

Without any code, this is hard. But here's my guess.
Perhaps it was made for Python 2 instead of Python 3, or the modules have been updated. Normally Python programs are run inside a virtual environments and have a requirements.txt file for the module versions. You can activate a virtual environment, install the packages and run it.
The issue arises from the wrong data type, the variable color should be of the type int or tuple. On line 278 of the file "D:\lib\site-packages\arcade\text.py" in draw_text, what is the type(key)?

Without code, it's hard to answer.
I think that when you decided the color that you wanted to use, probably in a text that you want to write on the screen, you chose the wrong format. You probably passed an array instead of a tuple that has this form: (int, int, int). (for (r, g, b)) if you did use an array you can still use it but you'll have to add the tuple(your_array) command when you're passing it at the place you want to pass it to.

Pyinstaller error Can't perform this operation for unregistered loader type (MacOS)

I need to display notifications in MacOS. Simply running the script with python can display notification. But whenever I pack the script using Pyinstaller, I get the following error. Seems like Pyinstaller is having some problem with working on Mac notifications. I also tried using pync (Python binding for terminal notifier). In all cases, simply running the app python notify.py works, but freezing the script using Pyinstaller doesn't seem to work.

I am using the following Python script to display notification
import Foundation
import objc
NSUserNotification = objc.lookUpClass('NSUserNotification')
NSUserNotificationCenter = objc.lookUpClass('NSUserNotificationCenter')
notification = NSUserNotification.alloc().init()
notification.setTitle_("TestTitle")
notification.setInformativeText_("This is sample text")
center = NSUserNotificationCenter.defaultUserNotificationCenter()
center.deliverNotification_(notification)

I had similar problems and this is how I made it work. You need not use Foundation as its making the problem with Pyinstaller (Not sure why this is causing an issue) and is not used elsewhere in your code.
import objc
NSUserNotification = objc.lookUpClass('NSUserNotification')
NSUserNotificationCenter = objc.lookUpClass('NSUserNotificationCenter')
notification = NSUserNotification.alloc().init()
notification.setTitle_("TestTitle")
notification.setInformativeText_("This is sample text")
center = NSUserNotificationCenter.defaultUserNotificationCenter()
center.deliverNotification_(notification)
At this point, it may throw some error or the notification just don't show up. Just add CFBundleIdentifier key into the info.plist file generated by pyinstaller.

Can't understand the error

Given below is the error which I am getting while running the code (which is in my previous post wx Import Error) in Python 2.6. Can anyone tell about this error? I am unable to understand it.

PyAssertionError: C++ assertion "bmp.Ok()" failed at ..\..\src\msw\dib.cpp(148) in wxDIB::Create(): wxDIB::Create(): invalid bitmap

Not sure if this is entirely related to your problem, but the SWIG-generated wrappers won't hold onto any Python objects passed to any set*() methods or the like in wx. You will need to hold onto such objects yourself or you will experience strange errors.

It looks like you have an invalid bitmap. In reading the tracebacks, it's usually the bottom traceback that's the most useful, and this one is saying that you have an "invalid bitmap".

Your application cant find an image file, put all images in one file and in your code give the exact path where to find the images.That wil solve that error.

OpenCV / Array should be CvMat or IplImage / Releasing a capture object

Edit : Array should be CvMat or IplImage is not an error message specific to this issue, that's the only most relevant error message i got.
I'm trying to make an *.exe out of an application using opencv.
I'm using Python 2.6 and openCV 2.1.
I can run part of the *.exe, i'm having a menu from where i can choose to process some pictures from 2 differents sources my webcam & a static image. The static image part works but when i'm chosing the webcam here is the output:

AttributeError: Game instance has no attribute 'bg'
My pyar.py file.
Building the *.exe with py2exe gave me this output :
The following modules appear to be missing
['ICCProfile', '_imaging_gif', '_scproxy']
I don't get it, this is working with my sources. I tried to pack my application with py2exe & pyinstaller, but the output is the same.
I guess the *.exe is missing something but i don't know what neither how to debug it.

It was not related to the packagers.
The problem was that I wasn't closing the webcam capture, several processes of my app were actually running in the background.
The doc is talking about ReleaseCapture but this function is apparently not in the python bindings, calling :
del(self.cam)
did the job just well, self.cam being my CvCapture object.
