I use anacoda distribution and SPYDER as my IDE. I have seen the many solutions related to key errors. But the movie wont run. How can I make the movie to run? I hope there are no other logical errors.

First install ffmpeg and add path to ffmpeg

# on windows
plt.rcParams['animation.ffmpeg_path'] = 'C:\\ffmpeg\\bin\\ffmpeg.exe'
# on linux
plt.rcParams['animation.ffmpeg_path'] = u'/home/username/anaconda/envs/env_name/bin/ffmpeg'    

Note for linux users: The path for ffmpeg can be found by simply using which: which ffmpeg

Also instead of

FFMpegWriter = animation.writers['ffmpeg']
writer = FFMpegWriter(fps=15, metadata=dict(artist='Me'),        bitrate=1800)

I just used writer = animation.FFMpegWriter()

How can I overcome this key word error?, First install ffmpeg and add path to ffmpeg # on windows plt.rcParams['animation.​ffmpeg_path'] = 'C:\\ffmpeg\\bin\\ffmpeg.exe' # on linux plt.

It seems that ffmpegis not installed on your system. Try the following code:

import matplotlib.animation as animation

It will print out a list of all available MovieWriters. If ffmpegis not among it, you need to install it first from the ffmpeg homepage.

What is the use of the 'this' keyword in Java?, Java "THIS" Keyword Keyword 'THIS' in Java is a reference variable that of constructor otherwise compiler will raise compilation error and only one this()  In this article, we are going to describe some of the most common SQL syntax errors, and explains how you can resolve these errors.

If you have Homebrew, literally just run the command

brew install ffmpeg

And Homebrew will take care of the rest (dependencies, etc). If you don't, I would recommend getting Homebrew or something like it (apt-get on Linux is built in, or an alternative on OS X would be Macports)

CodeNotes for C#, As a result, the aforementioned error is generated. The Base Keyword One way to overcome this problem is to simply give the Fruitclass a default noargument  First, let's distinguish between the types of errors: most compilers will give three types of compile-time alerts: compiler warnings, compiler errors, and linker errors. Although you don't want to ignore them, compiler warnings aren't something severe enough to actually keep your program from compiling.

I have also posed with same problem(keyError: 'ffmpeg') but instead of using anakonda, I used IDLE3. So, first i checked for 'ffmpeg' in terminal it wasn't installed so installed it.

Using: sudo apt install ffmpeg

and when I run my save_animation program, it worked generating animation files in '.mpeg' format.
