How to solve indexerror when running manim examples?

I just start learning manim and Im not so good at python.
when I was running manim examples given by the manim kindergarten, there was a error about index but I really don't know how to solve it.
As follows
manimgl example_scenes.py OpeningManimExample
Here is the information
Traceback (most recent call last):

IndexError: index -3 is out of bounds for axis 0 with size 0
It seems that the problem is about vectorized_mobject.py.
I've search all google but it seems no one has the same problem like mine.
In the docs of manim kindergarten I found no solution.
Hopefully some here once had the same problem and please let me know how to solve it.
Really thanks if someone could help me.

If you want to use Manim. I'd suggest you install ManimCE version from Manim Community. As it is more stable.
If you want to use, Manimgl to reproduce the animations from 3b1b videos.
Make sure you have FFmpeg and latex properly installed (Using
Miktex? make sure you enable it to install tex packages on it's own
or install all the latex packages).
Create a python virtual environment. Enable the venv you have just created.
Install manim using pip with pip install manimgl. Don't install it from
the source, as there are still some bugs at the time of writing.
If you followed all the steps correctly then running manimgl example_scenes.py OpeningManimExample should work.

Django Help - Basic Setup and Basic Functionality

Done my due diligence and still having issues. Here is my goal. I'm using Django with Python to create a website with some custom coded features. The problem I'm having is this. I've tried these tutorials: http://matthewdaly.co.uk/blog/2013/12/28/django-blog-tutorial-the-next-generation-part-1/
http://ferretfarmer.net/2013/09/05/tutorial-real-time-chat-with-django-twisted-and-websockets-part-1/ (would prefer to use just django and no twisted but open to anything.
Next to last is: http://www.djangorocks.com/tutorials/how-to-create-a-basic-blog-in-django/starting-your-application.html for blogs
And finally: creating a company site with blog, news pasting, etc. Most of which I can get via models as i have done in the past.
I've made progress: But I'm stuck at this part. When I try to run python manage.py runserver i get a huge error like this:
ages\django\conf\__init__.py", line 113, in __i nit__
[shenk#LUCY2 mytest]$ python manage.py runserver

Please excuse the formatting it is not cooperating 100%, working pretty good though.
Anyway I want to create a site with django and add on to it a bunch of hard coded basic modules which I can do. What I need help with as I believe I mentioned is why I cant do python manage.py runserver? Or the other question I had was the tutorials I found for blogs and such on Django were either out of date or did not work well. Please guide me towards the best way to create a company website with Django. For now I need basic skills similar to word press without and plugins (comments, blog, etc.) I can add more advanced functionality myself once this is working. The info on the Django Doc's only works like 20% of the time.
Any help would be appreciated, my preferred answer is a bit of an explanmation how to use it, as well as what could be causing my runserver issues.
Any response is much appreciated. I know this isn't the place, but send me a message on SO and perhaps we can work out payment in order to learn from you, get the base application done. After that I can write the other modules myself. (Yes, you'll be complicated and you can telecommute as I'm in PA outside Philly.
P.S. I'm an advanced C/C++ dev, a bit of C#, JS, Java, and mainly Python.
If you need any more info I can help. I'm great with python and even .NET MVC but django is a bit different so any guidance is appreciated.
Thanks in advance.

It says you've not configured the SECRET_KEY setting. You need to set the value of the SECRET_KEY variable in your_app_name/settings.py - if you used the command python manage.py startproject to create your Django project, it should have done this for you.
See here: https://docs.djangoproject.com/en/1.8/ref/settings/#secret-key

open settings.py
add
SECRET_KEY = "IWANTDJANGO4SUMREASON"
to the bottom

According to your error log, you've improperly configured your Django application. The SECRET_KEY setting must not be empty. Please check your settings.py which is loaded by manage.py and make sure the SECRET_KEY contains an appropriate value. That should get you somewhere further.
On the other hand, I would suggest reading the official documentation aswell as follow the official tutorial on how to get started. These are more often up-to-date and follow the official guidelines.

Pycharm 3.4.1 - "AppRegistryNotReady: Models aren't loaded yet". Django Rest framewrok

I'm using DRF and Pycharm 3.4.1 and Django 1.7. When I try to test my serializer class via Pycharm django console, it gives me the following error:
Code
from items_app.serializers import ItemSerializer
s = ItemSerializer()
print(repr(s))
then cause the following error traceback:

AppRegistryNotReady: Models aren't loaded yet.
but when I'm using my terminal(instead of pycharm django console), It works properly! I know there is a problem with Pycharm but I don't know how to fix it!

Loading the app registry is part of the django.setup method. If the app registry is not loaded when you start using the console, the most likely reason is that it is a plain python console instead of a fully blown Django console.
Try the following code. If that solves it, you are indeed using a plain python console.
>>> import django
>>> django.setup()

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.

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?
