Need jupyter-matplotlib 0.11 but can't upgrade

Empieza reproduciendo %matplotlib widget con las versiones de Python y Jupyter indicadas y, a continuación, inspecciona la salida de jupyter labextension list y las rutas de labextension del usuario y del entorno virtual que se muestran en el informe. Determina por qué la versión registrada de jupyter-matplotlib difiere de la versión instalada de ipympl; se considerará completado cuando la extensión se cargue sin el error MPLCanvasModel después del flujo de instalación o actualización indicado en el informe.

Describe the issue

When trying to plot something with %matplotlib widget I get the following error:

However python -m jupyter labextension update jupyter-matplotlib returns Extension 'jupyter-matplotlib' already up to date. And python -m jupyter labextension uninstall jupyter-matplotlib returns JupyterLab cannot uninstall jupyter-matplotlib since it was installed outside of JupyterLab. Use the same method used to install this extension to uninstall this extension.. Seems like some pip module is stopping me from modifying jupyter-matplotlib, but I can't see which. I've tried uninstalling and installing ipympl but no difference
