Poetry:

Pip and poetry should show the same things by virtue of poetry environments just being pipenvs under the hood:

In [3]:

!poetry config --list

In [4]:

!poetry env list

In [5]:

!poetry show

I didn’t do this programmatically, but it seems clear that poetry and pip are on the same page, but poetry gives more detailed information.

Container specifics

In [8]:

!cat /proc/cpuinfo

In [9]:

!cat /etc/os-release

In [10]:

!apt list

Watermark

This is a helpful tool in summarising Python environment from what might have been missed in previous output.

TODO: Use options from watermark…

In [12]:

%load_ext watermark

In [13]:

%watermark

Manim

Now that manim is installed, let’s try and configure a test video for our extension.

https://github.com/RickDW/manim-revealjs

In [5]:

# Need to import into Jupyter Kernel before we can call cell magic
# We could do something similar with watermark FWIW
import manim as mn
from manim_revealjs import PresentationScene, COMPLETE_LOOP

Manim Community v0.17.3

In [6]:

%%manim -qm -v WARNING DemoScene

mn.config.video_dir= "./videos"

class DemoScene(PresentationScene):
    def construct(self):
        # TODO find out why end_fragment has the t parameter
        rect = mn.Rectangle(fill_color=mn.BLUE, fill_opacity=1)
        self.play(mn.Create(rect))
        self.end_fragment()

        self.play(rect.animate.shift(mn.UP).rotate(mn.PI / 3))
        self.end_fragment(fragment_type=COMPLETE_LOOP)

        self.play(rect.animate.shift(3*mn.LEFT))
        self.end_fragment()
