Intellisense for site-packages doesn't work as intended

[python4ever]

Environment data

VS Code version: Newest
Python Extension version: 2018.1.0
Python Version: 3.6.4
OS and version: Windows 10 x64

Actual behavior

Intellisense does not work, sometimes partially work I guess

Expected behavior

Well I guess it should work all the time

Steps to reproduce:

• I opened a project dir in vs code
• I write a code like this:

• It doesn't even suggest train_data or anything. The pop-up showed up, because after writing a dot I pressed Ctrl+Space

It works good for my own classe (if I make some dummy class Foo then it shows available methods after the dot). It may sometimes show up but like after 5-10 seconds? I guess thats too much and I remember working with this extension without that trouble. It does something like this:

I tried it on multiple machines (with Linux too), fresh installations, new files/folders, nothing does work. My settings.json:

{
    "editor.renderWhitespace": "all",
    "window.zoomLevel": 0,
    "vim.disableExtension": false,
    // Python setting
    "files.exclude": {

    },
    "window.menuBarVisibility": "default",
    "vim.otherModesKeyBindings": [
        {
            "before": [
                "^"
            ],
            "after": [
                "z",
                "z"
            ]
        }
    ],
}

Am I doing something wrong?

Same problem encountered.

VS Code version: 1.20.0
Python Extension version: 2018.1.0
Python Version: 3.6.4
OS and version: Windows 10 x64

Intelligence for function open does not work.

And this is what developer's tool shows

Is this the problem of my network?

• What is the python interperter is used by VS Code?
  The Python version will be displayed on the bottom left of the VS Code status bar.
  Please check the tooltip to identify the path of the python interpreter.
• Confirm pandas is installed in the Python interpreter used by VS Code (see above)
• Finally, please test this the Insiders Build of our extension.
  We've fixed a number of issues related to intellisense and its possible this too has been resolved in the dev version (to be released within a week or so).

@kjgfcdb Please could you too install the Insiders build of the extension.

NOTE: I'm not referring to the Insiders Build of VS Code.

[kjgfcdb]

@DonJayamanne Unfortunately the Insiders build of the extension still fails to fix this problem, here is the screen shot.

Interpreter:
python 3.5.2 (downloaded from python.org)

This problem occurs when I import the numpy library and type "np.". Then the intellisense crashes and error message appears in developer's tool again and again.

import numpy as np
np.

@frynio I unfortunately can't directly reproduce:

I did have to wait for the Jedi cache to warm up, though.

@kjgfcdb What version of NumPy are you running? For me on CPython 3.6.3 and numpy 1.14.1 I am getting intellisense.

[DonJayamanne]

@kjgfcdb
Please could you provide the information requested above, also please could you download and install the latest Insider Build of the extension. It contains a fix for one of the errors reported above.

[kjgfcdb]

@brettcannon The NumPy that I am running is numpy 1.14.1.
@DonJayamanne The latest version of this extension still failed to fix this problem. And this time the error becomes this:

[DonJayamanne]

@kjgfcdb
Please could you try the following:

• pip install jedi
• Then execute the following code:

import jedi
source = """
import numpy as np
np.
"""

script = jedi.Script(source=source, line=3, column=3, path='one.py')
completions = script.completions()
print(len(completions))

[kjgfcdb]

@DonJayamanne OK, the output is 912, and it seems that this problem only occurs when I use numpy. For other packages like jedi,matplotlib and so on, the intelligence works very well.

[brettcannon]

I still can't reproduce, even with from numpy import *. @kjgfcdb do you have any sample code you can provide which consistently triggers this? Otherwise you can wait until our experimental analysis engine becomes available.

[julKali]

I can confirm this bug. For me it's not only numpy but also scipy and matplotlib (these are the ones I tested).

See this issue: microsoft/vscode#47360

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.
