Environment data

VS Code version: Version 1.18.0-insider
Commit: 509630ffe3fabf2e1f49b416bb83f5ff0877b042
Python Extension version: 0.7.0
Python Version:
python2.7 --version
Python 2.7.14 (which is the one I want)

python --version
Python 3.6.2 (which is the default os system)

OS and version: Arch Linux (Rolling Release, updated)

Actual behavior

AFAIK Ctags file is correctly generated, but CTRL+R is not showing any symbol.

Expected behavior

Explore against the symbols of the file.

Steps to reproduce:

• Open any Python file
• Press CTRL+R
• Wait until it says "No symbols found"

Sorry, but what command does Press CTRL+R invoke.
Is this Go to symbol in file or Go to symbol in workspace.
Also, please could you provide a screen sample of the message No symbols found

Hi there again,

AFAIK the CTRL+R is trying to invoke the Go to symbol in file.

On the other hand, here I attach a gif with that section of the screen, I attach it as a gif, so you can see how it responds.

Which I found weirder, is that the Go to symbol in workspace is working.

[DonJayamanne]

Have you configured your workspace/user settings to ensure it points to Python2.7 (the one you want)?
Please could you upload the code for the above file?
Does the feature Go to symbol in file work for other files or does it not work at all?

i've got the same issue. i've made sure that the tags file has been generated, and python.pythonPath points to the right installation, however the go to symbol in file does not work. it works for other files, e.g. markdown. also go to definition cannot be used, while intellisense is working all right.

As @Tantalus13A98B5F described.

I've made sure the tags are generated, and the python.pythonPath is ok, it works with Markdown, ruby, etc... but not here in python. Also tried to disable every linter/stuff non-python related but still :(

As for your questions, @DonJayamanne for now the config is like this:

As for the settings, here are they
settings.json.txt
attached as a json.

Well. I looked into the code today. I'm using jedi 0.11.0, which is just incompatible with the current extentsion:
The error occurred in pythonFiles/completion.py.
In JediCompletion._extract_range, it goes:

if jedi.__version__ in ('0.9.0', '0.10.0'):
    return self._extract_range_jedi_0_9_0(definition)
else:
    return self._extract_range_jedi_0_10_1(definition)

The fallback behavior uses the following module:

from jedi.parser.python import parse

However, it doesn't exists there for jedi 0.11.0.
Then I switched to the preview version of jedi in the repo and the problem is gone.

@JustDevZero maybe you should check the version of your jedi, and it's ok if python.jediPath is not configured.
@DonJayamanne the current code cannot work with jedi 0.11.

[JustDevZero]

Hi there again,

I've tried the advice from @Tantalus13A98B5F, reverting the version of jedi, from 0.11 to 0.8 (the old one), but now, instead of "No symbols", I've got an eternal loading...

Here's gif attached.

We have updated the version of Jedi in the extension. Is this still an issue for people?

[brettcannon]

Closing due to lack of response for more info. If the info is provided in the future we will be happy to re-open this.
