%matplotlib widget run time error

首先在所报告的 Linux、Python 3.12.4 和 VS Code 环境中复现 %matplotlib widget，然后检查 matplotlib/backends/registry.py 中显示的后端解析路径。将其行为与 ipympl 和 Jupyter 的集成设置进行比较；确定了此配置的原因和可复现的解决方案后，即表示完成。

Hello,
I saw an old issue about this topic, but I could not find a recent solution.
I am using a Linux machine, Python version 3.12.4. I created my environment and I installed matplotlib by using
pip install matplotlib

But when I run my code in VS code, I get a runtime error related to %matplotlib widget

RuntimeError Traceback (most recent call last)
File ~/.conda/envs/s_i/lib/python3.12/site-packages/matplotlib/backends/registry.py:413, in BackendRegistry.resolve_gui_or_backend(self, gui_or_backend)
412 try:
--> 413 return self.resolve_backend(gui_or_backend)
414 except Exception: # KeyError ?

File ~/.conda/envs/s_i/lib/python3.12/site-packages/matplotlib/backends/registry.py:375, in BackendRegistry.resolve_backend(self, backend)
374 if gui is None:
--> 375 raise RuntimeError(f"'{backend}' is not a recognised backend name")
377 return backend, gui if gui != "headless" else None

RuntimeError: 'widget' is not a recognised backend name

During handling of the above exception, another exception occurred:

--> 415 raise RuntimeError(
416 f"'{gui_or_backend} is not a recognised GUI loop or backend name")

RuntimeError: 'widget is not a recognised GUI loop or backend name

Have you found a solution for this issue?
thank you
