Error when trying to run Opening Manim Scene

[sydelcid]

Description of bug / unexpected behavior

Hi, I am facing an error when trying to run Opening Manim Scene. Other examples seem to run fine. The issue seems to be on the "Tex" function. However, I'm also getting a lot of warnings even before this. I don't seem to face issues when not using "Tex", for example "MathTex" and "Text" work fine in various examples. However, when using "Text", it doesn't seem to fit the text on the canvas and it runs out of screen.

Expected behavior

Expected to produce the gif provided in the examples section.

How to reproduce the issue

Copied same code as provided in the Examples section "Opening Manim Scene".

Additional comments

Maybe the problem is conversion from dvi to svg.

[naveen521kk]

Looks like a problem with miktex. Where it didn't provide the necessary svg file. Maybe try reinstalling?

[sydelcid]

Thanks for looking into it. It seems to work perfectly fine with MathTex and Text. The "Tex" command gives error somehow, not sure why. Also, the warnings may be about the rendering, but the main error seems to be in substring split, if someone could comment on this:

File "openmanim.py", line 4, in construct
title = Tex("This is some \LaTeX")
File "c:\users\syd\anaconda3\envs\qclearnz\lib\site-packages\manim\mobject\svg\tex_mobject.py", line 362, in init
self.break_up_by_substrings(config)
File "c:\users\syd\anaconda3\envs\qclearnz\lib\site-packages\manim\mobject\svg\tex_mobject.py", line 399, in break_up_by_substrings
sub_tex_mob.move_to(self.submobjects[last_submob_index], RIGHT)
IndexError: list index out of range

[behackl]

title = Tex("This is some \LaTeX")

You either need to duplicate backslashes (\\LaTeX) or use raw strings (Tex(r"This is some \LaTeX")). The example in our documentation uses double backslashes (https://docs.manim.community/en/v0.1.1/examples.html#openingmanim).

In case this is just a display bug and you actually have double backslashes: can you please paste the full source code that you are trying to render, along with the full output of

manim .\openmanim.py OpeningManim -v DEBUG  --disable_caching

in a comment here?

[naveen521kk]

Also, please clean your media directory. --disable_caching doesn't check for it.

[behackl]

@sydelcid any update on this?

[wurmfood]

Not the original person, but I'm seeing the same behavior.

Code:

from manim import *

class Opening(Scene):
    def construct(self):
        title = Tex("Text")
        self.play(Write(title))
        self.wait()

Terminal output:

Using Text instead of Tex works just fine. MathTex also works. However:

title = MathTex("\\text{Text}"}

will also fail with the same error as using Tex.

Finally, using latex commands from the terminal to render it as a PDF works just fine.

tldr: dvisvgm is broken with the default miktex install. If you get the version from the dvisvgm website (v. 2.11), it works.

Trying to find more information about this, I tried using dvisvgm directly.

PS D:\David\Repositories\manim\media\Tex> dvisvgm -p 1 .\9d34656f5a56ec89.dvi -n -v2 -o .\math.svg
PS D:\David\Repositories\manim\media\Tex> dvisvgm -p 1 .\a5bd540987ea901a.dvi -n -v2 -o .\tex.svg
WARNING: failed to create ecrm1000.gf
PS D:\David\Repositories\manim\media\Tex> dvisvgm -V
dvisvgm 2.8.2

Both DVIs work just fine (tested using yap from MikTex). It looks like it's the conversion that's the problem.

In the SVGs created, the ones that don't work are missing the paths under defs. That's why it can't find them. It looks like this might be a problem with dvisvgm. Assuming this to be true I downloaded the latest dvisvgm from https://dvisvgm.de/Downloads/. Replacing that version with the one from MikTex worked.

[tmelorc]

I also got problem with dvisvgm. So hat I did was run pdflatex instead of latex. I don't know what is advantage to use dvi instead of pdf.

[pinjuf]

Also had the exact same problem, replacing dvisvgm didn't help. I replaced MikTeX with TeX Live and everything worked perfectly fine.

We've had this report less often in recent times. The usual solution is to install the cm-super LaTeX package.
