Problem Description

Jupyter qtconsole displays docstrings while spyder 4.0.0 b2 instelled in the same environment
does not, which I expected.

What steps reproduce the problem?

1. import numpy as np
2. numpy.abs(

What is the expected output? What do you see instead?

Expected to see docstring as in jupyter qtconsole:

Instead I see an empty box:

All run from the same python 3.7 env (see below for conda list

[ccordoba12]

Thanks for reporting, I noticed this too. It's a regression from our refactoring of editor and console calltips.

@dalthviz, please take a look at this one. The idea is to try to detect the object's signature and also display a bit of its docstring (which is very similar to the way things are working on the editor).

[BjornFJohansson]

Thanks for the attention and for editing the title!
