The code completion in the editor is not working

[FuZhiyu]

Description

What steps will reproduce the problem?

1. type "import os"
2. type long_name_for_completion = 1
3. type long_name, press tab (or control + space), nothing happens.
4. type os., press tab, nothing happens.

What is the expected output? What do you see instead?
There should be a list of possible variable names for me to choose when I press tab.

Please provide any additional information below
It works in the IPython console, but not the editor.

Actually one hour ago it works well in the editor. Just after a dinner it is not working.
I've tried reinstalling spyder, rebooting, updating the packages, etc. It still doesn't work.

If you are using Anaconda, please run in a terminal

conda update jedi

and try again.

[FuZhiyu]

Thanks for your reply. I've updated it to the latest version but it still not working.

Besides, the object inspector is not working either. When I press cmd+I at an object in the editor, the Help will show nothing. However, if I do the same thing in the IPython Console, it still works.

I have the same problem. I use WinPython. This problem does not exist with Spyder 3.1.3 and jedi 0.9.0 on my computer.

Let's consolidate this on issue #4410.

[ccordoba12]

@arman00, the problem seems to exclusive to WinPython, at least on Windows.

[arman00]

I am not sure if it is Windows specific or not. FuZhiyu says it happens on MacOS.

[ccordoba12]

@arman00, I'm not saying it's a Windows only issue. What I'm saying is the this problem seems to occur only with WinPython on Windows.

Could you try with Anaconda and report on issue #4410? Thanks!

[stonebig]

hum, jedi-dev trunk has about 3 performance patches since jedi-0.10.2. maybe shall we just switch to jedi-dev until jedi-0.10.3 is out

[stonebig]

ipython 6 claims for jedi>=0.10. Even jedi0.10.3_trunk_of_2017-05-24 doesn't resolve the issue on Windows/WinPython (make it worth than jedi-0.10.2).

So the choice is between ipython-6.0 (and 6.1 in a few days) or jedi-0.9.0, until problem goes away.

[arman00]

@ccordoba12 , oh I see.. I don't use Anaconda, may try to install it and test if I find time. Thank you!

[stonebig]

apparently, the auto-completion works again with ipython-6.1.0 and Spyder-3.2dev

[FuZhiyu]

@ccordoba12
here it doesn't work again. I have done nothing. No update and no change of setting. It seems very unstable.

[arman00]

@stonebig
It doesn't work with ipython-6.1.0 and Spyder 3.1.4. Is there a particular reason for Spyder 3.2dev , or do I need to update to this version?

[stonebig]

In pure truth, I don't know what improved things:

• either a practice of waiting 5 minutes after start (until all processes have calm down) before first try,
• either an update in ipython-6.1 or spyder-3.2dev.

Here is the reference I see on the underlying issue
ipython/ipython#10493 (comment)

[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.

Following issue #5782 for spyder=3.2.6 and python 3.6.3 Anaconda, Windows 8.1 x64:

pip uninstall enum34
restarting spyder

was able to solve my problem with missing autocomplete.

[thomiko]

@EonSin Thanks a million for the hint with enum34! I uninstalled it with pip and code completion works perfectly after restarting spyder.
