Parameters of python's functions doesn't appear when I hit 'tab'

Question

It might sound stupid, but the jupyter notebook I'm using is, probably, not configured as it should.

Everytime I hit 'tab' when the cursor is within a function, the parameters doesn't appear in the top of the list. Any tip here?

Found this on stack over flow TAB completion does not work in Jupyter Notebook but fine in iPython terminal

the solution seems to be to run:

pip3 install jedi==0.17.2
