Autocomplete not working in editor

[nbroers]

Description of your problem

Autocomplete stopped working in the Spyder editor (it worked before, but no longer).

What steps will reproduce the problem?

1. Fresh install of Spyder and upgrade all dependencies
2. Reset Spyder to factory settings
3. Type the following in a new file:

jannie = 'aaa'
jann

(Followed by CTRL + SPACE to activate autocomplete). Nothing happens. No output in Python console.

Also, no results when attempting auto-complete for built-in modules, functions, etc.

If I go to Consoles -> Open a Python Console and do the same, then autocomplete does work.

I can confirm that CTRL + SPACE also works correctly in the Sublime Text editor.

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

Expected popup of autocomplete dialog. No popup appeared.

Thanks for reporting. This is a duplicate of issue #4410.

We still don't know why but autocompletion is working fine for Anaconda users and broken for some users that don't use it.

So my suggestion is to use Anaconda instead of your own Python installation, if possible.

[kepy97]

I just reinstalled anaconda and auto completion working now.

Steps that I followed:

1> Uninstall Anaconda from control panel
2> Restart Computer
3> Download and install anconda from [https://www.anaconda.com/download/#windows]
4> Restart again before it you start anaconda.
5> done.

Have faced the same problem today. Auto-completion works fine in IPython console but not working in Editor for Pandas functions.

What steps will reproduce the problem?
-- Fresh install from Anaconda
-- When I type in a new line
jannie = 'aaa'
jann

It works fine in Editor (either by TAB or CTRL+SPACE) and IPython Console.

But in another example:

import re
import pandas as pd

time_sentences = ["Monday: The doctor's appointment is at 2:45pm.", 
                  "Tuesday: The dentist's appointment is at 11:30 am.",
                  "Wednesday: At 7:00pm, there is a basketball game!",
                  "Thursday: Be back home by 11:15 pm at the latest.",
                  "Friday: Take the train at 08:10 am, arrive at 09:00am."]

df = pd.DataFrame(time_sentences, columns=['text'])

When I type

df.te

and strike TAB (or CNTR+SPACE), nothing happens in Editor, though it works fine in IPython Console.

Autocompletion does not work for me either in editor nor in Ipython console. Sometimes it does sometimes not. And it is very slow if it happens to work.

I'm seeing a slight variation of this. On my system, Autocomplete works fine when I first start Spyder, but then after a while (I am not sure what, maybe some form of power event), it ceases to work. Everything else seems to be working fine.

Is there a separate issue related to that? Or should I create one?

I am on Anaconda 3, very latest, Spyder:

[ccordoba12]

@lleeoo, please don't open more issues about this. Right now we're working on replacing our current completion architecture for a new one, but that work is going to land in Spyder 4. Due to that, we're not going to try to fix this problem in Spyder 3.

[sparkstars]

Auto completion was working for me on Console but not in the editor (SPYDER).
updated the Jedi using below command in terminal and its working fine now:
conda update jedi

[mehtadarshak]

On my mac, it wasn't working earlier when I was keeping spyder IDE open and anaconda (its parent window) close.
I reopened spyder and this time kept anaconda open as well, and autocomplete started working.

No complications needed.

Cheers

I have solved this issue removing and installing again the "rope" pkg for python.

sudo pip3 install rope

This fixed the issue for me

sad to say but spyder has by far proven to be the most unstable IDE I ever used. Have been trying to fix things around since morning and stuff keeps breaking one after the other. And now I am again trying to look for why autocomplete isn't working :(
This is not the first time this issue has happened, seems more like Spyder’s internal decision decides when autocomplete should work and when not depending on the day of the week.
