Tex File doesn't exist in example_scenes.py example

Describe the error

The display of example scene went wrong while running. Tex File doesn’t exist.

Code and Error

Code:

1. Clone the repo
2. cd into and pip install -e .
3. manimgl example_scenes.py OpeningManimExample as described in the README

Error: The first line is from print(f"opening {os.path.dirname(tex_file)}") in utils/tex_file_writing.py:text_to_dvi function, I think this is where the problem is: something went wrong when parsing the IntegerMatrix’s brackets string and got it into the text_file variable.

 LaTeX Error!  Not a worry, it happens to the best of us.

I’m getting the same error. I have

I had the same problem. And today I finally solved it. You have “~” sign in your directory name. I have changed my path and some modified the source code and then it worked for me.

Can you share the changes you made to the path/source code?

Hi,

Sorry for adding to a closed ticket but if you face this issue too, there is a simpler solution which is to specify a temp path in the manim config (<PATH_TO_MANIM_SRC>/manimlib/default_config.yml). You’ll find a parameter named “temporary_storage”, just give a valid path for this one.

If not present the librairy will fetch this from your TMP environment variable, which may contains a ~ causing this issue, by providing the path you bypass this problem.
