Can I ran it in Colab?

[qo4on]

I have a bunch of errors with this:
!pip3 install jupyter-manim

[krassowski]

Previously users have run it in Colab, so you should be fine. Please paste the errors that you see - otherwise this would is a guessing game.

Seems resolved based on #2 (comment)... @qo4on, if you open a bunch of issues in different repositories without providing the details, it may frustrate the maintainers. Please mind our time - no one pays us for this.

Also, if you have already found a solution for your problem, please post it in the issues/close them, so that others can benefit. This is all about helping each other. You are very welcome here, but please do help us help you.

I did this thing in Colab:

!rm -rf sample_data
!sudo apt-get -qq install texlive-full
!sudo apt-get -qq install ffmpeg
!sudo apt-get -qq install sox
!sudo apt-get -qq install libcairo2-dev libjpeg-dev libgif-dev python3-dev libffi-dev
!python3 -m pip install -q pyreadline
!python3 -m pip install -q pydub
!git clone -q https://github.com/3b1b/manim.git > /dev/null
%cd manim
!python3 -m pip install -qr requirements.txt

It took awhile. After that it seems to work fine and the code below generates a video:
!python3 -m manim example_scenes.py SquareToCircle -pl

Then I did this:
!pip3 install jupyter-manim
with some errors:

ERROR: manimlib 0.1.10 has requirement numpy==1.15.0, but you'll have numpy 1.16.4 which is incompatible.

And Colab asks to restart environment.
Finally I managed to get it work. The code below showed a video inside the notebook.

import jupyter_manim

%%manim Shapes --base64
from manimlib.scene.scene import Scene
from manimlib.mobject.geometry import Circle
from manimlib.animation.creation import ShowCreation

class Shapes(Scene):

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

Is that ok, can I safely ignore these errors?

[krassowski]

Thank you! I cannot tell for certain, but these mostly seem as minor version bumps, you may be fine - and as you said it's working.

This errors/warnings steam from the fact that you installed a development version of manim from GitHub, rather than the one available via pip3. Was this your choice, or was it that the pip version did not work?

[qo4on]

I did not succeed with pip3, but maybe I did something wrong there. I spent a couple of hours looking for right commands. I think it's worth putting Colab example in the installation guide.

• Some features doesn't work: I noticed that full screen button is gray, can't turn on.

• Is it possible to change fps to 15 for preview? Changing resolution -r 480,854 works perfectly.

[krassowski]

• I think that the full-screen button is a browser-dependent thing.
• most (but not all) of the standard parameters/toggles of the manim should work. Get a full list of those with

%%manim -h
pass

For example, the online example uses --low_quality to render faster.

Thank you!

• I'm not sure if it's the browser's fault. I have latest Chrome 79.0.3945.130 (Official Build) (64-bit) (cohort: Stable).

• There's no framerate in help. I'm a new to Manim, need to delve deeper in it.
