Manjaro 安装使用manim

一开始按照这个教程做,但是他的教程是对于debian用户的。

malhotra5/Manim-Tutorial

Clone Manim

git clone https://github.com/3b1b/manim

manjaro 安装ffmpeg, sox, cairo, latex:

sudo pacman -S ffmpeg sox cairo 
sudo pacman -S texlive-core texlive-humanities texlive-latexextra texlive-publishers texlive-fontsextra texlive-science texlive-langchinese
sudo pacman -S scipy

(对latex不是很熟悉所以就把textlive-most相关的全装了)

我还把requirements.txt里面的部分版本号给去掉了, 避免出现版本不匹配的错误.

测试

安装完成之后可以在项目目录执行

python3 -m manim example_scenes.py SquareToCircle -pl

来测试是否安装成功。

测试通过之后也可以通过这份代码来测试latex是否安装成功。

from manimlib.imports import *

class Equations(Scene):
    def construct(self):
        #Making equations
        first_eq = TextMobject("$$J(\\theta) = -\\frac{1}{m} [\\sum_{i=1}^{m} y^{(i)} \\log{h_{\\theta}(x^{(i)})} + (1-y^{(i)}) \\log{(1-h_{\\theta}(x^{(i)}))}] $$")
        second_eq = ["$J(\\theta_{0}, \\theta_{1})$", "=", "$\\frac{1}{2m}$", "$\\sum\\limits_{i=1}^m$", "(", "$h_{\\theta}(x^{(i)})$", "-", "$y^{(i)}$", "$)^2$"]

        second_mob = TextMobject(*second_eq)

        for i,item in enumerate(second_mob):
            if(i != 0):
                item.next_to(second_mob[i-1],RIGHT)

        eq2 = VGroup(*second_mob)

        des1 = TextMobject("With manim, you can write complex equations like this...")
        des2 = TextMobject("Or this...")
        des3 = TextMobject("And it looks nice!!")

        #Coloring equations
        second_mob.set_color_by_gradient("#33ccff","#ff00ff")

        #Positioning equations
        des1.shift(2*UP)
        des2.shift(2*UP)

        #Animating equations
        self.play(Write(des1))
        self.play(Write(first_eq))
        self.play(ReplacementTransform(des1, des2), Transform(first_eq, eq2))
        self.wait(1)

        for i, item in enumerate(eq2):
            if (i<2):
                eq2[i].set_color(color=PURPLE)
            else:
                eq2[i].set_color(color="#00FFFF")

        self.add(eq2)
        self.wait(1)
        self.play(FadeOutAndShiftDown(eq2), FadeOutAndShiftDown(first_eq), Transform(des2, des3))
        self.wait(2)

执行

python3 -m manim pythonFile.py className -pl
