Summary
Version:
- jupyter_matlab_proxy: 0.15.2
- MATLAB: R2024a Update 6 (24.1.0.2689473)
- Python: 3.10.13
- Jupyter Lab: 4.3.0
Environment:
- OS: Arch Linux
- Browser: Firefox
Description:
The rendering of the symbolic toolbox fails when executing even the simplest symbolic expression. The expected output is not produced, and an error message is displayed instead.
Steps to Reproduce:
- Launch Jupyter Lab.
- Create a new MATLAB notebook.
- Execute the following code:
sym x x
Expected Behavior:
The expected behavior is that the symbolic variable x should be displayed without any errors.
Actual Behavior:
The following error message is displayed instead:

Additional Information:
- The issue seems to persist across different sessions and with various symbolic expressions.
- No modifications have been made to the MATLAB installation that could affect the symbolic toolbox.

The langchain_core.pydantic_v1 module was a compatibility shim for pydantic v1, and should no longer be used. Please update the code to import from Pydantic directly.
For example, replace imports like: `from langchain_core.pydantic_v1 import BaseModel`
with: `from pydantic import BaseModel`
or the v1 compatibility namespace if you are working in a code base that has not been fully upgraded to pydantic 2 yet. from pydantic.v1 import BaseModel
