BUG : MESA 2.3

[AlABarazi]

Hi,
I am getting this error when I run the code with mesa2.3. No problems with 2.1
`

Thanks for reporting a potential bug. Which exact Mesa version are you running? If not 2.3.2, could you update to it (with pip install --upgrade mesa)?

FutureWarning: The Mesa Model class was not initialized. In the future, you need to explicitly initialize the Model by calling super().__init__() on initialization.

Do you understand this warning? If you do this, it might already solve your problem.

If that doesn’t help, could you post a minimal reproducible example?

[AlABarazi]

Thanks for the answers. Yes I understand the warning . I will update the code. I am using 2.3.0 . Also 2.3.1 has the same issue.
I can post minimal reproducible code if nothing worked out.

The problem was caused because I have used a customized schedule instead of the one that come with MESA library. I have stoped working on this project for a year and forgot about this.
The problem has nothing to do with mesa 2.1 or 2.3.
Please delete the whole issue if possible.
