Pressing Tab creates a space instead of autocomplete

[hardianlawi]

With Jedi autocomplete in Jupyter, when you press TAB, it will simply show a list of suggestions but after installing TabNine, pressing Tab would give you a whitespace. The first picture is what I would expect, but I got the second pic instead which is a complete deal breaker for me.

Is there any way to get the behaviour of first picture while still using TabNine?
