How to show all methods possible in jupyter notebook in MacOS?

Question

I found similar questions but none relate to my issue in MacOS

Many people didn't find those answers useful in MacOS as you can see in the comments.

I'm trying to use . + tab to display all the possible methods any initialized object in Jupyter notebook like this:

(example image of a list object for context)

and none will show up. But in memory variables can be shown.

I'm launching Jupyter Notebook from my MacOS terminal from a virtual environment with the following versions

jupyter==1.0.0
jupyter-client==5.3.1
jupyter-console==6.0.0
jupyter-core==4.5.0

How can I configure Jupyter Notebook in order to show all possible methods when I use tab?

UPDATE

Upgraded to notebook==6.0.1 and still doesn't work
In the same environment, ipython displays methods when using tab
%config IPCompleter.greedy=True was set and still doesn't work
pyreadline installed still doesn't work
it worked with lists but with a pandas empty data frame df. + tab wont display possible methods neither with an Axessubplot object.
This issue was replicated in a linux distro and the notebook hangs in kernel busy by using one thread by 100% until it finally displays the possible methods. In MacOs it doesn't hang in 'kernel busy' and won't display anything only when you add a hint (like df.h + tab will show head and hist)

You have initialized `a`, right? – Sam Chats Aug 30 '19 at 14:34 — Sam Chats, Aug 30 '19 at 14:34
Yes, the object I'm 'tabing' is initialized already – Gonzalo Garcia Aug 30 '19 at 14:50 — Gonzalo Garcia, Aug 30 '19 at 14:50

I found that this issue was discussed here Autocomplete not working

You should downgrade your ipython version to 6.2.1 by running in your virtual environment:

pip install ipython==6.2.1

and then restart the jupyter notebook. Now it should display the methods of any object including pandas and seaborn ones like this

`! jupyter notebook --version: 5.7.8` and it's not working by replicating your example with `time` library. I will try to downgrade my Jupyter notebook version and update my comment. Thanks – Gonzalo Garcia Aug 30 '19 at 14:55
Downgraded to `5.7.4` with `tornado 4.2.0` and it didn't work neither – Gonzalo Garcia Aug 30 '19 at 15:02
@GonzaloGarcia have you installed `readline`? https://stackoverflow.com/questions/33665039/tab-completion-does-not-work-in-jupyter-notebook-but-fine-in-ipython-terminal – ComplicatedPhenomenon Aug 30 '19 at 15:17

Yes. I have installed `pyreadline` and also added `%config IPCompleter.greedy=True` And still doesn't work – Gonzalo Garcia Aug 30 '19 at 15:28
@GonzaloGarcia Did it work when you use `Ipython` in the terminal? – ComplicatedPhenomenon Aug 30 '19 at 15:30

Now it works with lists but not with an empty dataframe of pandas or axesublplot of seaborn, neither in ipython nor jupyter – Gonzalo Garcia Aug 30 '19 at 15:39

It worked with the first link, do you want to update your answer ? by downgrading ipython to version 6.2.1. – Gonzalo Garcia Aug 30 '19 at 15:55

@GonzaloGarcia Glad to hear that, you can edit my answer or you can give your own answer. – ComplicatedPhenomenon Aug 30 '19 at 15:59

I have Jupyter notebook on Ubuntu Server running with Python3

Here what helped in my case:

Infastructure update

I had fresh install, so update pip3 package

python3 -m pip install --upgrade pip
See if there are any outdated packages

python3 -m pip list --outdated --format=freeze
If there are any (which is highly possible) use this to update everything

python3 -m pip list --outdated --format=freeze | grep -v '^-e' | cut -d = -f 1 | xargs -n1 python3 -m pip install -U
In my case I've also installed python3-cairo-dev

Also it is important to remember, that you better have item defined first. Like

myAwesomeList = []
myAwesomeList.<- here we press "Tab"
