Using manim by 3Blue1Brown

I first tried 3Blue1Brown's repository and then try the community manim.

• Switch Python 3.7 in Kubuntu 18.04 How to upgrade to python 3.7 on Ubuntu 18.10
• sudo apt-get install python3.7
• sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 1
• sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.7 2
• sudo update-alternatives --config python3
  choose /usr/bin/python3.7 manual mode (for me it was 2.)
• For picairo build: sudo apt-get install python3.7-dev
• sudo apt-get install python3.7-dbg
• Install manimlib| Install doc|Fodora 29/Ubuntu 18 manim installation
  • git clone https://github.com/3b1b/manim.git
  • Cairo: sudo apt-get install libcairo2-dev
  • ffmpeg: sudo apt-get install ffmpeg
  • sox: sudo apt-get install sox
  • ffmpeg: sudo apt-get install ffmpeg
  • also venv, sudo apt-get install python3-venv
  • at manim dir, python3 -m venv manim-venv
    I failed this by the following error.
    

    The virtual environment was not created successfully because ensurepip is not
    available.  On Debian/Ubuntu systems, you need to install the python3-venv
    package using the following command.
    
      apt-get install python3-venv
    
    You may need to use sudo with that command.  After installing the python3-venv
    package, recreate your virtual environment.
            

    Thus, I installed venv. note: python3-venv will be python 3.6's venv, so,
    apt-get install python3.7-venv
  • source manim-venv/bin/activate
  • I am in the virtual environment, the prompt is (manim-env) hioshi...[120]bash %
  • Under the virtual environment, python3 -m pip install -r requirements.txt
  • run example:
    python -m manim ${manim_prog.py} ${ManimFunc} -pl
    Ex: python -m manim func_01.py AddUpdaterFunc -pl
• Windows manim install
• Download and install
  • MikTex: basic-miktex-2.9.7342.exe (32bit), add path: C:\Program Files\MiKTeX 2.9\miktex\bin\x64
  • python3, python-3.8.1-amd64.exe, add path automatically if checked at the install panel
  • ffmpeg, ffmpeg-4.2.2-win64-static.zip, expand and add path: C:\Program Files\ffmpeg-4.2.2\bin
  • sox, sox-14.4.2-win32.exe, Add path C:\Program Files (x86)\sox-14-4-2
  • pycairo, downloaded pre compiled whl file, pycairo-1.19.0-cp38-cp38-win_amd64.whl from https://www.lfd.uci.edu/~gohlke/pythonlibs/. pip install pycairo-1.19.0-cp38-cp38-win_amd64.whl
  • manim, zip download, pip install -r requirements.txt (but I found visual studio compiler dependency. I recommend to download precompiled version for each requirements manually.)

Using manim by community

I tried the cloned repository instead of pip package on Linux.

• See the community manim documentation. Install binaries
  • git clone https://github.com/ManimCommunity/manim.git
  • sudo apt install libcairo2-dev
  • sudo apt install ffmpeg
  • sudo apt install texlive texlive-latex-extra texlive-fonts-extra texlive-latex-recommended texlive-science texlive-fonts-extra tipa
  • sudo apt install python3-pip
  • sudo apt install curl
  • curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python3
  • # cd manim directory ${HOME}/.poetry/bin
  • # add path ${HOME}/.poetry/bin
  • poetry env use 3.7
  • # At the directory where you see the pyproject.toml file
  • poetry install
• Use poetry
  1. # At the directory where you see the pyproject.toml file
  2. poetry shell
  3. # move to your project dir
  4. python3 -m manim scene.py -p -ql
• Tips
  • Disable console color output: set environment variable NO_COLOR (see python rich module: rich console API)

Tutorials and resources

• Tutorials, Examples
  • Manim-Tutorial on github
  • Talking physics manim tutorial
  • Manim tutorial by Theorem of Beethoven, Manim tutorial video series by Theorem of Beethoven (YouTube channel)
  • 3b1b_manim_examples
• Internationalization
  • Manim has a switch to use xelatex at manim/manimlib/constants.py, TEX_USE_CTEX option, set to True for use xelatex.
  • With utf-8, German Umlaute and some Japanese was accepted, but 「対頂角」 failed. To solve this problem add following usepackages to manim/manimlib/ctex_template.tex.

              % For German, add ngerman (there is a babel line in the template.)
              \usepackage[english,ngerman]{babel}
    
              % for Japanese
              \usepackage{xeCJK}
              \setCJKmainfont{IPAexGothic}
              \setCJKsansfont{IPAexMincho}
              

• Set a video player on KDE
  • On KDE, manimlib/constants.py's STREAMING_CLIENT (= "ffplay") is not respected. The KDE's file association was chosen. To set the file association on KDE (tested 18_04), System Settings -- Applications -- File Associations, on Configire file associations: video -- mp4. e.g., VLC media player
