in command prompt above shown message. problem in faulthandler module. how should rectify it? installed jupyter notebook using "pip". new python programming , jupyter. please me resolve this.

we accidentally made release of ipykernel package doesn't work on python 3.5 on windows. once realised this, made new release (version 4.3.1) fix it.

you can upgrade running:

pip install --upgrade ipykernel

if had installed ipykernel using conda, command be:

conda update ipykernel
