$pip install jupyter_contrib_nbextensions $pip install. Since version 0.2.0, this nbextension is enabled by default on enabling the jupyter_nbextensions_configurator serverextension, but it can be disabled as with any other. I’m encountering a 403 forbidden error when trying to use a virtual environment with jupyter notebook (version below 7).
Error · Issue 160 · Jupytercontrib/jupyter_nbextensions_configurator
I had the same problem, solved by install notebook for 6.1.1 version.
It is possible that a recent power cut that.
Here is the env details/package version. The error occurs while attempting to configure. You have to prefix it by ! It’s impossible to get the links “to access the server in the browser” because they disappear from the terminal so quickly due to the flood of tornado errors below.
I am able to use the url to access the configurator tab (meaning that everything is installed properly?), but i cannot see the configurator tab in my jupyter: I am using python 3.12.3. It has been running fine until now. In short, for a better experience don't use an exclamation point in combination with pip or conda.

2.) installation was successful, but after opening jupyter.
Hi all, all of a sudden i’m getting a “403 forbidden” error when running jupyter notebook. I installed nbextension and configurator by the commands: When running on the notebook.
