However, it says that notebook is too new to install and even when I installed the older versions of the notebook, still it did not work out.
I am using Windows 10, so the install procedure is a bit different.
However I found out that when I do the following command
jupyter contrib nbextension install --user
I receive the following error.
File "C:\Program Files\Python310\lib\site-packages\jupyter_nbextensions_configurator\__init__.py", line 18, in <module>
from notebook.base.handlers import APIHandler, IPythonHandler
ModuleNotFoundError: No module named 'notebook.base'
According to Bing AI, I have to user older Jupyter Notebook.
In Jupyter Notebook version 7.0 or later, this error occurs because the notebook.base module has been removed.2 Therefore, downgrading the Jupyter Notebook version to 6.5 or lower may resolve the issue. Therefore, downgrading the Jupyter Notebook version to 6.5 or lower may resolve the issue.
