manim系列教程01-windows平台安装manim

微博@mlln-cn, 并附上文章url链接, 我就能回答你的问题奥!

manim是用python开发的数学可视化的工具, 作者热衷于做一些数学知识的普及视频, 因而做了这个库, 后来开源了这个库, 我们得以使用, 下面这篇文章介绍了如何安装manim以及它所依赖的各种软件, 过程虽然麻烦, 但是并不难。

环境介绍

我使用win10(64位)系统, python3.6已经安装完毕, 并且已经安装好了jupyter notebook ,
所以这两个的安装方法就不再赘述。
由于我们整个系列教程都在jupyter notebook 中完成, 所以我们今天不仅仅要安装manim, 而且要让他在notebook中运行。

使用pip安装manimlib

使用如下命令安装manimlib

1
pip install manimlib

如果你安装失败, 并且提示编码错误, 请先将你的win10系统的默认编码改成”utf-8”。

安装FFmpeg

FFmpeg是一个视频处理工具, 安装方法很简单, 只需要现在文件, 放到一个你喜欢的位置即可。

下载地址: https://www.gyan.dev/ffmpeg/builds/ffmpeg-git-full.7z

解压得到这几个文件:

接下来需要将ffmpeg的所在文件夹添加到Path路径中, 我们文章后面”设置环境变量”中会介绍

安装pycairo

我们首先下载已经编译好的库, 下载地址在这里:

https://www.lfd.uci.edu/~gohlke/pythonlibs/#pycairo

由于我的python是3.6 64位, 因此我下载的是”pycairo‑1.20.0‑cp36‑cp36m‑win_amd64.whl”;

然后在命令行输入:

1
pip install PathToTheFile/pycairo‑1.20.0‑cp36‑cp36m‑win_amd64.whl

很快就能安装完毕, 输出是:

Processing d:\notebooks\pycairo-1.20.0-cp36-cp36m-win_amd64.whl
pycairo is already installed with the same version as the provided wheel. Use --force-reinstall to force an installation of the wheel.

安装Miktex

  • 打开你下载的安装文件, 你会看到这个, 点击”下一步”

  • 首先我们要下载安装包

  • 一般不需要完整安装, 只需要基本功能, 选择第一个

  • 选择一个服务器, 选择China的服务器, 速度比较快

  • 选项下载文件夹, 点击下一步就开始下载了, 记住你的这个下载文件夹, 后面要打开这个文件夹

  • 打开你下载好的文件, 然后双击’setup-4.1.1-x64.exe’来安装:

  • 为所有用户安装

  • 设置安装路径:

  • 到此安装完毕

安装Sox

  • 下载最新版本, 我下载的是14.4

下载地址是: https://sourceforge.net/projects/sox/files/sox/14.4.2/

  • 下载完成以后, 双击文件就可以开始安装:

  • 设置安装路径, 点击”install”, 基本上这样就安装完毕了, 后面需要将sox的安装路径添加到环境变量”path”中, 最后会讲

安装 jupyter-manim

使用pip安装:

1
pip3 install jupyter-manim

我们会看到安装成功的提示:

设置环境变量

上面安装了一些windows软件, 然而我们的python想要调用这些软件(比如ffmpeg)需要将这些软件的安装路径配置到Path环境变量中。

  • 打开”我的电脑”的”属性”

  • 打开”高级系统设置”中的”环境变量”

  • 编辑”Path”这个变量, 然后新增”ffmpeg”的安装路径:

  • 同样的方法添加sox的安装路径:

测试安装是否成功

为了能使用魔法%%manim, 我们首先要引入 jupyter_manim:

1
import jupyter_manim

下面, %%manim就可以使用了, 我们测试一下:

from manimlib.mobject.geometry import Circle
from manimlib.animation.creation import ShowCreation

class Shapes(Scene):

def construct(self):
circle = Circle()
self.play(ShowCreation(circle))
输出(html):
