how to solve these?

arbaleast commented 2 years ago

Thanks, I'm already work out these problem.

arbaleast commented 2 years ago

but I'm rookies, I don't know how to use fourier.py For example, should I call this function ?

def get_fourier_graph(
    axes, time_func, t_min, t_max,
    n_samples = NUM_SAMPLES_FOR_FFT,
    complex_to_real_func = lambda z : z.real,
    color = RED,
    )

and how to set parameters.Thanks in advance.

can you tell me how to resolve this, I have the same problem

you need manim_imports_ext.py and custom, put them together like this image

Don't use the community version to render 3b1b's video code.

how to solve these?

Part 1 (Error)

In the module error is for not recognize the root folder. The solution is add the module sys and also add sys.path.append('.') in your file if it is in: --root/ ---fourier.py But if your file is in: --root/ ---fourier/ ----fourier.py Then add sys.path.append('..')

Part 2 (Scene)

The principal is the use of the scenes at execute the command manimgl. For example manimgl fourier.py [nameScene].

pyiso80 commented 2 years ago

I've been trying to run 3b1b videos using manimgl. The manim_imports_ext not found can be fixed with 3 methods as far as I could figure out: 1) adding these 3 lines in the newton_fractal.py file for instance

import sys sys.path.append(".") sys.path.append("..")

and running manimgl newton_fractal.py SceneName in Terminal.

2)running the following in Terminal before executing manimgl. Of course you will have to change the path to point to your project folder where 3b1b's src files are placed export PYTHONPATH=${PYTHONPATH}:/Users/john/Manim/videos

3)I use VSCode and my tasks.json file looks like the following. This is my most preferred way since I use VSCode and running the scene files with tasks is easier.

{ "version": "2.0.0", "tasks": [ { "label": "Render", "type": "shell", "command": "export PYTHONPATH=${PYTHONPATH}:${workspaceFolder};manimgl ${file} ${input:Scene} ${input:opt}", "problemMatcher": [], "group": { "kind": "build", "isDefault": true } } ], "inputs": [ { "id": "Scene", "type": "command", "command": "memento.promptString", "args": { "id": "Scene", "description": "Enter Scene:", "default": "", "type": "promptString" } }, { "id": "opt", "type": "command", "command": "memento.promptString", "args": { "id": "opt", "description": "Render options", "default": "-s", } }

],

}

Expanding on option 2 to make it more permanent for windows 10 users: 1) Search for "Edit system environmental variables" in the windows search bar and click that 2) Click the "Environment Variables" option 3) In the User variables section, either click "New" if PYTHONPATH variable doesn't exists already, or "Edit" if it is there 4) Add the path of where manim_imports_ext.py is located 5) Click OK/apply to everything and restart your shell

Don't add anything to PATH.

Include custom_config.yml: and it should be fixed.

Your folder hierarchy should look like this: image

andrewHolsaeter commented 2 years ago

Neither of us suggested adding anything to PATH. We were suggesting adding to PYTHONPATH which is a list of directories python will use to check for locally installed packages/modules, i.e. main_imports_ext.py.

The problem is that each video code calls from manim_imports_ext import * as the first line of code to execute. If python doesn't find main_imports_ext installed globally, it will look for the module/file in the same directory as the executing script. And obviously it doesn't find it due to the nested folder structure of this repo.

Maybe I'm completely missing something here (very much possible), like something in relation to manim, but there is no way a fresh clone of this and the manim repo will be able to run these video scripts based on the current README isntructions.

Perhaps you (and the devs) intstalled mainim_imports_ext.py globally and forgot about this behavior?
