54 | Function graphs to updaters : Hi everyone i don't know how to create this animation: add a decimal number "a", With the change of a, y also changes, y=a, and create a rectangular coordinate system with time as the horizontal axis and y as the vertical axis. Updater and ValueTracker seems to have no effect. Elteoremadebeethoven made a tutorial about updaters. (without graphs) But it's still hard to make this animation with graph. Here is my code:
```
class UpdaterTest9(GraphScene):
def construct(self):
# global number_value
numberplane = NumberPlane()
self.add(numberplane)
self.setup_axes()
line = Square()
line2 = Circle()
number = DecimalNumber(0, num_decimal_places=5)
# number.add_updater(lambda m: m.set_value(get_area(line)))
def number_updater(obj):
obj.add_updater(lambda m: m.set_value(get_area(line)))
# self.get_graph(lambda x: x.set_value(get_area(line)))
number.add_updater(number_updater)
# if number.get_value() != 0:
number_value = number.get_value()
graph = self.get_graph(
x_values=[0, number_value],
y_values=[0, number_value],
# func=lambda x: 0
func=number_value
)
graph.add_updater(number_updater)
self.add(number, graph)
self.play(Transform(line, line2), rate_func=linear, run_time=8)
self.wait(2)
```
```
class UpdaterTest10(GraphScene):
def construct(self):
# global number_value
numberplane = NumberPlane()
self.add(numberplane)
self.setup_axes()
line = Square()
line2 = Circle()
vt = ValueTracker(0)
number = DecimalNumber(0, num_decimal_places=5)
# numberv = ChangeDecimalToValue(decimal_mob=number)
# numberv = CountInDecimal()
# number.add_updater(lambda m: m.set_value(get_area(line)))
def number_updater(obj):
obj.add_updater(lambda m: m.set_value(vt.get_value(get_area(line))))
# self.get_graph(lambda x: x.set_value(get_area(line)))
number.add_updater(number_updater)
# if number.get_value() != 0:
number_value = number
# number_value.add_updater(lambda m: m.set_value(number))
def number_value_updater(obj):
obj.add_updater(lambda m: m.set_value(number))
# graph = self.get_graph(
# x_values=[],
# y_values=[],
# # func=lambda x: 0
# func=number_value_updater(obj)
#
# ).add_updater(number_value_updater)

52 | Manim Installation Unsuccesfull "IndexError: list index out of range" : after the installation of manim I tried to use the command line in the command promt
python -m manim example_scenes.py SquareToCircle -pl
this works just fine, the problem araise when i try to use the command
python -m manim example_scenes.py WriteStuff -pl

I can tell that if I do as it is said it works for the WriteStuff, but then after even the most basic exercise related to text generation fails which remaind me of this

45 | Positional arguments are missing (kwargs) : I'm learning Manim through your video tutorial. Thank you for giving us such a great opportunity to learn how to use it.
Currently I'm investigating the making use of arrays (Manim tutorial | 3). Almost every one of 26 classes (FormulaColor1, CrossText, etc) from 3_text_like_arrays.py give an error:
` __init__() missing 1 required positional argument: 'kwargs'`
I suppose some configuration parameters are missing, but I don't know how to set them. I use Win10 x64.
For example, when calling FormulaColor1, which is:
```
class FormulaColor1(Scene):
def construct(self):
text = TexMobject("x","=","{a","\\over","b}")
text[0].set_color(RED)
text[1].set_color(BLUE)
text[2].set_color(GREEN)
text[3].set_color(ORANGE)
text[4].set_color("#DC28E2")
self.play(Write(text))
self.wait(2)
```
I receive this error:
```
Traceback (most recent call last):

and added this creatures to the file c_creature (renamed pi_creature) for example this one
```python
class PlusCreature(CCreature):
CONFIG = {
"file_name_prefix": "PlusCreatures"
}
```
and i changed method 'create_c_creatures()' in class TeacherStudentsScene in file c_creature_scene.py (renamed pi_creature_scene.py)
```python
def create_c_creatures(self):
self.teacher = CCreature(color=self.teacher_color)
self.teacher.to_corner(DOWN + RIGHT)
self.teacher.look(DOWN + LEFT)
'''From that
self.students = VGroup(*[
Randolph(color=c)
for c in self.student_colors
])
'''
# To this
print("yessssss its runing, we are creating students.")
self.students = VGroup(*[
random.choice([PlusCreature,
MinusCreature,
MultiCreature,
DivCreature,
RemCreature,
AndCreature,
EqualCreature,
RoundBracketsCreature,
CurlyBracketsCreature,
SquareBracketsCreature,
AngleBracketsCreature,
HashCreature,
QuestionCreature])(color=c)
for c in self.student_colors
])
self.students.arrange(RIGHT)
self.students.scale(self.student_scale_factor)
self.students.to_corner(DOWN + LEFT)
self.teacher.look_at(self.students[-1].eyes)
for student in self.students:
student.look_at(self.teacher.eyes)
return [self.teacher] + list(self.students)
```
i created file manimlib.imports_with_c that imports c_creatures instead of pi_creatures
when i run following code ( i tried self.setup() and self.c_creatures = VGroup(*self.create_c_creatures()) but this lines just create another creatures onto previouse ones)
```python
from manimlib.imports_with_c import *
class ts(TeacherStudentsScene):
def construct(self):
#self.setup()
#self.c_creatures = VGroup(*self.create_c_creatures())
self.teacher_says(
"Something different today!",
run_time = 2
)
```
## Output always shows same students with two EqualCreatures and one QuestionCreature even when rendering code again and again but according to changes in method 'create_c_creatures()' in class TeacherStudentsScene in file c_creature_scene.py it should be create random creatures everytimes i run the code
same output is following
it always print the output from line print("yessssss its runing, we are creating students.") in create_c_creatures() method that means it runs every time between multiple renders. this mean may be there is something wrong with random.choice() method
but i tried following code.
```python
import random
def a1():
return "1"
def a2():
return "2"
def a3():
return "3"
def a4():
return "4"
def a5():
return "5"
numbers = [*[random.choice([a1,a2,a3,a4,a5])() for i in range(0,20)]]
print(numbers)
```
it allways print random numbers.
but when i put this code inside create_c_creatures() like follow
```python
print("yessssss its runing, we are creating students.")
self.students = VGroup(*[
random.choice([PlusCreature,
MinusCreature,
MultiCreature,
DivCreature,
RemCreature,
AndCreature,
EqualCreature,
RoundBracketsCreature,
CurlyBracketsCreature,
SquareBracketsCreature,
AngleBracketsCreature,
HashCreature,
QuestionCreature])(color=c)
for c in self.student_colors
])
def a1():
return "1"
def a2():
return "2"
def a3():
return "3"
def a4():
return "4"
def a5():
return "5"
numbers = [*[random.choice([a1, a2, a3, a4, a5])() for i in range(0, 20)]]
print(numbers)
```
now it always shows same numbers.
# then whats wrong with my code ? why always same students ? | [
"it solved by putting random.seed()\r\n```python \r\nrandom.seed()\r\nself.students = VGroup(*[\r\n random.choice([PlusCreature,\r\n MinusCreature,\r\n MultiCreature,\r\n DivCreature,\r\n RemCreature,\r\n ... |

I met this problem when I was trying to enable Tikz like in your tutorial. I followed every step, but I am using the latest manim not 3 Feb one. And when I compiled ExampleTikz scene, I got
I put Tikz packages in both tex_template.tex and ctex_template.tex.
I have checked all the issues, but my problem exists.
I also see ur responses in other places, so I will follow your step. the *latex* commander can be recognized, but I am not sure if I am missing packages or it might be other problems.

24 | Hola! Tengo una duda respecto a los gráficos en manim : Hola! sin antes disculparme con esta básica pregunta, quería plantearte una duda que me surgió al realizar gráficos de funciones, pues no encontré información en internet respecto esta.
Bien, mi duda es que, ¿Cómo hago para disminuir el tamaño de los ejes y de la función ?, pues si escalo la variable "graph" sólo se escala el gráfico de mi función, mas no los ejes "x" e "y". Además, ¿Cómo hago para animar un movimiento de esta? Había pensado en definir un mismo gráfico dos veces, con distintas posiciones, pero esto resulta imposible pues los "ejes" se definen una sóla vez
Espero se entiendan mis preguntas
Saludos y de ante mano muchas gracias ! | [

# Points to consider before writing your issue
* This repository works with the Manim version of February 3, unless otherwise indicated. If your code does not work, check that you are using the correct version.
* At the moment Manim works with Python 3.7, not with 3.8. This is because several of the dependencies have not yet been updated.
* If the terminal throws an error, please write it completely with the markdown format.
* Be clear and specific with your problem, share the code (and files, if applicable) and the command you use when rendering the video.

8 | Install requirements for Cairo / Ubuntu 18.04 : Hello! I just wanted to report a minor issue that I encountered, to help people in the future. I am running on Ubuntu 18.04, and had both python 3.6 and python 3.7 already installed. When installing the dependencies for Cairo, I encountered no problem. However, when installing Cairo itself, I get an error about a missing header "Python.h". The reason is simply that when executing
```bash
sudo apt install python3-dev

the package manager installed the headers for python 3.6. Installing explicitly the correct version, *i.e.*, `python3.7-dev`, solved the issue.

45 | Positional arguments are missing (kwargs) : I'm learning Manim through your video tutorial. Thank you for giving us such a great opportunity to learn how to use it.
Currently I'm investigating the making use of arrays (Manim tutorial | 3). Almost every one of 26 classes (FormulaColor1, CrossText, etc) from 3_text_like_arrays.py give an error:
` __init__() missing 1 required positional argument: 'kwargs'`
I suppose some configuration parameters are missing, but I don't know how to set them. I use Win10 x64.
For example, when calling FormulaColor1, which is:
```
class FormulaColor1(Scene):
def construct(self):
text = TexMobject("x","=","{a","\\over","b}")
text[0].set_color(RED)
text[1].set_color(BLUE)
text[2].set_color(GREEN)
text[3].set_color(ORANGE)
text[4].set_color("#DC28E2")
self.play(Write(text))

```
i created file manimlib.imports_with_c that imports c_creatures instead of pi_creatures
when i run following code ( i tried self.setup() and self.c_creatures = VGroup(*self.create_c_creatures()) but this lines just create another creatures onto previouse ones)
```python
from manimlib.imports_with_c import *
class ts(TeacherStudentsScene):
def construct(self):
#self.setup()
#self.c_creatures = VGroup(*self.create_c_creatures())
self.teacher_says(
"Something different today!",
run_time = 2
)
```
## Output always shows same students with two EqualCreatures and one QuestionCreature even when rendering code again and again but according to changes in method 'create_c_creatures()' in class TeacherStudentsScene in file c_creature_scene.py it should be create random creatures everytimes i run the code
same output is following
it always print the output from line print("yessssss its runing, we are creating students.") in create_c_creatures() method that means it runs every time between multiple renders. this mean may be there is something wrong with random.choice() method
but i tried following code.
```python
import random
def a1():
return "1"
def a2():
return "2"
def a3():
return "3"
def a4():
return "4"
def a5():
return "5"
numbers = [*[random.choice([a1,a2,a3,a4,a5])() for i in range(0,20)]]
print(numbers)
```
it allways print random numbers.
but when i put this code inside create_c_creatures() like follow
```python
print("yessssss its runing, we are creating students.")
self.students = VGroup(*[
random.choice([PlusCreature,
MinusCreature,
MultiCreature,
DivCreature,
RemCreature,
AndCreature,
EqualCreature,
RoundBracketsCreature,
CurlyBracketsCreature,
SquareBracketsCreature,
AngleBracketsCreature,
HashCreature,
QuestionCreature])(color=c)
for c in self.student_colors
])
def a1():
return "1"
def a2():
return "2"
def a3():
return "3"
def a4():
return "4"
def a5():
return "5"
numbers = [*[random.choice([a1, a2, a3, a4, a5])() for i in range(0, 20)]]
print(numbers)
```
now it always shows same numbers.
# then whats wrong with my code ? why always same students ? | [
"it solved by putting random.seed()\r\n```python \r\nrandom.seed()\r\nself.students = VGroup(*[\r\n random.choice([PlusCreature,\r\n MinusCreature,\r\n MultiCreature,\r\n DivCreature,\r\n RemCreature,\r\n ... |

I met this problem when I was trying to enable Tikz like in your tutorial. I followed every step, but I am using the latest manim not 3 Feb one. And when I compiled ExampleTikz scene, I got
I put Tikz packages in both tex_template.tex and ctex_template.tex.
I have checked all the issues, but my problem exists.
I also see ur responses in other places, so I will follow your step. the *latex* commander can be recognized, but I am not sure if I am missing packages or it might be other problems.

24 | Hola! Tengo una duda respecto a los gráficos en manim : Hola! sin antes disculparme con esta básica pregunta, quería plantearte una duda que me surgió al realizar gráficos de funciones, pues no encontré información en internet respecto esta.
Bien, mi duda es que, ¿Cómo hago para disminuir el tamaño de los ejes y de la función ?, pues si escalo la variable "graph" sólo se escala el gráfico de mi función, mas no los ejes "x" e "y". Además, ¿Cómo hago para animar un movimiento de esta? Había pensado en definir un mismo gráfico dos veces, con distintas posiciones, pero esto resulta imposible pues los "ejes" se definen una sóla vez
Espero se entiendan mis preguntas
Saludos y de ante mano muchas gracias ! | [
"Puedes crear los ejes que quieras usando `Axes`, ver [aquí](https://github.com/3b1b/manim/blob/48f2a1ec3c86f3ad26b6b1292b6917149005cbab/manimlib/mobject/coordinate_systems.py#L129), ya que este objeto tiene el método [`get_graph()`](https://github.com/3b1b/manim/blob/48f2a1ec3c86f3ad26b6b1292b6917149005cbab/maniml... |

22 | Necesito ayuda para poder instalar manim. Mi problema básicamente es con la instalación de Pycairo. De igual forma instalé ffmpeg de una diferente, pero si se instaló, solo que no me instala el pycairo. : # __**WARNING**__

# Points to consider before writing your issue
* This repository works with the Manim version of February 3, unless otherwise indicated. If your code does not work, check that you are using the correct version.
* At the moment Manim works with Python 3.7, not with 3.8. This is because several of the dependencies have not yet been updated.
* If the terminal throws an error, please write it completely with the markdown format.
* Be clear and specific with your problem, share the code (and files, if applicable) and the command you use when rendering the video.

21 | Error when trying to use text like arrays : I write this in my code, and it works fine:
`title = TexMobject("\\frac{tanx - \\sqrt{3}}{2cosx + 1} = 0")`
But when I write like this:
`title = TexMobject("\\frac{","tanx","-\\sqrt{3}}{","2cosx","+1} = 0")`
I got `Xelatex error converting to dvi`
What's the problem here? | [
"Like I said in my [video](https://www.youtube.com/watch?v=DGSj7weT-y8&t=8m37s) don't use `\\frac` to fragment formulas, use `\\over`."
