This means Cairo/Pango failed to find fonts for some reason. Most probably just restarting the PC should fix this. Try deleting media/ in cwd and run again and report the output.

2 years ago What's is the version of Cairo used? The below snippet should tell you the version.
import manimpango
manimpango.cairo_version()Also, how did you install Cairo?
Does this snippet run?
import manimpango
print(manimpango.list_fonts())(if yes, can you paste the output?)

2 years ago Hello Naveen,
Thank you again. I installed Cairo using Homebrew with:
brew install cairoThe following is the Python code snippet of what I tried:
import manimpango
manimpango.cairo_version()
# output was '1.16.0'
a = manimpango.list_fonts() # this runs alright
print(len(a)) # so there were 316 fonts
for font in a:
if "Noto" in font:
print(font)
''' The following are the ones I found (Noto Sans wasn't found)
Noto Mono for Powerline
Noto Nastaliq Urdu
Noto Sans Anatolian Hieroglyphs
Noto Sans Egyptian Hieroglyphs
Noto Sans Kannada
Noto Sans Myanmar
Noto Sans Oriya
Noto Serif Myanmar
'''Because I could not find Noto Sans font in the list, I retried the algorithm as below:
from manim import *
import manimpango
class FontsExample(Scene):
def construct(self):
ft1 = Text("Noto Mono for Powerline", font="Noto Mono for Powerline")
self.add(ft1)However, this still gave me the same error as below:

2 years ago Hmm, I think you would need to report a bug upstream as they may help you better debug it. First, let's check whether we can reproduce this with a C program: https://raw.githubusercontent.com/GNOME/pango/main/examples/cairosimple.c Try downloading and building it by
curl -OL https://raw.githubusercontent.com/GNOME/pango/main/examples/cairosimple.c
gcc cairosimple.c `pkg-config --libs --cflags pangocairo` -o test
./test test.pngAnd see if the error happens there. If it happens there too please reply.

2 years ago Thank you for the quick reply.
I just tried it immediately and confused that with GCC it somehow works quite well.
(I got a pretty picture with Tests and Salems on as attached :) )
Guess my Python 3 interpreter is experiencing some trouble seeing what my GCC is seeing
(and any advice on how to report a bug upstream? I never tried it)
Thank you again!

2 years ago I just tried it immediately and confused that with GCC it somehow works quite well.
Hmm, that makes it even more confusing, since you can't report it upstream. They would ask for a C-reproducer.
Maybe GCC finds a different version of Pango and Cairo than what ManimPango was compiled with? I would need the output of the following commands to verify that, run these whichever terminal you used to run manim (I hope you ran that GCC command in the same shell too).
which pkg-config
pkg-config --libs --cflags pangocairo
which python
python --version --version
python -c 'import manimpango; print(manimpango.__file__)'
python -c 'import manim; print(manim.__file__)'
python -c 'import manim; print(manim.pango_version())'
python -c 'import manim; print(manim.cairo_version())'Hello Naveen,
The last two lines of the suggested code gave me a peculiar error.

It's me who typed it wrong, it should be
python -c 'import manimpango; print(manimpango.pango_version())'
python -c 'import manimpango; print(manimpango.cairo_version())'From the other things I noticed, do you conda-forge python by default? Can you run pip install manimpango --force --no-binary :all: and see if that fixes the problem (it recompiles the binding, maybe it should work)? Can you also try install Manim on homebrew provided Python?

2 years ago Hello Naveen,
Sorry for the late response to the comment. I just tried the commands you suggested, and I got:
khan ~/fun_codes/manim_tutorial > python -c 'import manimpango; print(manimpango.pango_version())'
1.50.6
khan ~/fun_codes/manim_tutorial > python -c 'import manimpango; print(manimpango.cairo_version())'
1.16.0I do use conda-forge by default as well.
And I did try the
pip install manimpango --force --no-binary :all:as well, but didn't solve the problem.
And... it might be a very silly question, but how do I install Manim on homebrew provided python?
Thank you again!

ExpatError: no element found: line 1, column 0@naveen521kk @kyunghoon-han I finally got manim working with Text(..) on M2. So far I was using conda env. But now I switched to using the system python and used venv. That seemed to solve the problem. I installed all libraries same way as before. Although I am not 100% sure if environment switching is indeed responsible for the fix. If I will investigate further and post here.
Description of bug / unexpected behavior
Hello all,
I was following the tutorial provided by the Manim Community web-page, and noticed that somehow Cairo was not behaving as I expected...
The following is the code I copied from the tutorial
and the following is the error message I received: Assertion failed: (!"reached"), function _cairo_hash_table_lookup_unique_key, file cairo-hash.c, line 251.
Any idea on how this problem can be resolved?
Thank you in advance,
Best, K
