%matplotlib widget run time error

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:

RuntimeError Traceback (most recent call last)

414 except Exception: # KeyError ?
--> 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

Commence par reproduire %matplotlib widget dans l’environnement indiqué avec Linux, Python 3.12.4 et VS Code, puis examine le chemin de résolution du backend affiché dans matplotlib/backends/registry.py. Compare le comportement avec la configuration de l’intégration d’ipympl et de Jupyter ; le travail est terminé lorsque la cause et une résolution reproductible pour cette configuration ont été identifiées.
