Introduction

Manim is a powerful Python library used for creating mathematical animations. The Manim Cell extension is a Jupyter Notebook extension that allows users to create interactive Manim animations directly within their notebooks. However, some users have reported issues with the Preview Manim Cell feature, where it crashes after displaying a single frame. In this article, we will explore the possible causes of this issue and provide a step-by-step guide to troubleshoot and resolve it.

Description of the Issue

The Preview Manim Cell link boots up Manim, but only displays a single frame at the scene location before crashing with the error AttributeError: 'InteractiveShellEmbed' object has no attribute 'magic'. This issue occurs on a Windows 10 machine with the latest Manim (1.7.2) installed in a fresh Python 3.12 virtual environment, where only setuptools and manimgl were installed via pip.

Possible Causes

Based on the stack trace and log file, it appears that the issue is related to an IPython "autoreload all" command. This command is used to automatically reload modules when they change, which can cause issues with the Manim Cell extension.

Troubleshooting Steps

To troubleshoot and resolve this issue, follow these steps:

Step 1: Check the Manim Version

Ensure that you are using the latest version of Manim (1.7.2) by running the following command in your terminal:

pip install --upgrade manim

Step 2: Check the Python Version

Ensure that you are using the latest version of Python (3.12) by running the following command in your terminal:

python --version

Step 3: Check the IPython Version

Ensure that you are using the latest version of IPython by running the following command in your terminal:

pip install --upgrade ipython

Step 4: Disable Autoreload

Disable the autoreload feature in IPython by adding the following line to your ~/.ipython/profile_default/ipython_config.py file:

c.InteractiveShellEmbed.autoreload = 0

Step 5: Reinstall Manim Cell

Reinstall the Manim Cell extension by running the following command in your terminal:

pip uninstall manimcell
pip install manimcell

Step 6: Restart Jupyter Notebook

Restart Jupyter Notebook by running the following command in your terminal:

jupyter notebook restart

Conclusion

In conclusion, the Preview Manim Cell feature crashing after displaying a single frame on Windows is likely caused by an IPython "autoreload all" command.
