Need steps and procedure to avoid the problem of launching Jupyter-notebook at event later times.

Unexpected behavior observed with launching of “jupyter-notebook and jupyter notebook” command:
box@box-virtual-machine:~/python_programs$ jupyter notebook
Traceback (most recent call last):

Look up here :

It is due to problem in traitlets module latest version. Work around is to revert traitlets from 5.10.0 to 5.9.0

Traitlets is a pure Python library enabling:

the enforcement of strong typing for attributes of Python objects (typed attributes are called “traits”);
dynamically calculated default values;
automatic validation and coercion of trait attributes when attempting a change;
registering for receiving notifications when trait values change;
reading configuring values from files or from command line arguments - a distinct layer on top of traitlets, so you may use traitlets without the configuration machinery.

After reverting from 5.10.0 to 5.9.0 , jupyter notebook got launched

thank you for resolving issues.
