RuntimeError:Matplotlib动画中没有MovieWriters [英] RuntimeError: No MovieWriters available in Matplotlib animation

问题描述

我遇到的问题是类似于以下示例的代码: https://matplotlib.org/examples/animation/basic_example_writer.html

The problem I am getting is in code similar to this example: https://matplotlib.org/examples/animation/basic_example_writer.html

错误:

运行时错误:在上面的示例中，Writer = animation.writers['ffmpeg']处没有可用的MovieWriters .

RuntimeError: No MovieWriters available occurs at Writer = animation.writers['ffmpeg'] in the example above.

我正在使用Mac，已经使用brew安装了ffmpeg，甚至使用conda进行了安装，即使我没有为该特定代码使用anaconda.

I am using mac, I have installed ffmpeg using brew, and even installed it with conda even though I am not using anaconda for this particular code.

我肯定它已安装-我已经在终端中使用它来更改文件，但是它在程序中不起作用.

I am positive that it is installed - I have used it in terminal to change files but it is not working within the program.

谢谢！

推荐答案

尝试像

import matplotlib.pyplot as plt
plt.rcParams['animation.ffmpeg_path'] = '/usr/local/bin/ffmpeg'

您必须将这些代码行放在脚本的开头，然后使用动画Writer.

You have to put these code lines at the beginning of a script and then use animation Writer.
