can't autocomplete for cv2

Environment data

VS Code version: 1.19.2
Python Extension version: 0.9.1
Python Version: 3.5.2
OS and version: ubuntu 16.04.02

Actual behavior

Expected behavior

Expect more autocompletions

Steps to reproduce:

• pip install opencv-python
• import cv2

Some test

I did some interesting test on py-extension's jedi. I new a test.py in the path where jedi locate in extension'~/.vscode/extensions/ms-python.python-0.9.1/pythonFiles/preview/jedi'. Then I import this jedi module.

• In VScode, I excuted the test.py with F5:

      import jedi
      print(jedi.__file__)
      print(jedi.Script("import cv2\ncv2.").completions())

Output from Console window (Help->Developer Tools menu)

~/.vscode/extensions/ms-python.python-0.9.1/pythonFiles/preview/jedi/__init__.py
ImportError: numpy.core.multiarray failed to import
[<Completion: cv2>, <Completion: data>, <Completion: haarcascades>, <Completion: importlib>, <Completion: os>, <Completion: __doc__>, <Completion: __file__>, <Completion: __name__>, <Completion: __package__>]

But when I excuted code in my Terminal using 'python test.py', the output is the correct autocompletion and this is just done by extension's jedi:
Output from Terminal

I had finally find the solution, the key point is about the Numpy's version!!! It seems that in py-extension, the jedi can't work with the Numpy's newest version(1.14.0) and the python3's cv2 module can only be autocompleted when numpy work well. So I changed Numpy version to 1.10.0, then everything OK!!!

It may be worth reporting this directly to jedi

@MikhailArkhipov After more testing and thinking, I found that it may not be the jedi's fault. I both test the jedi module in vscode's F5 and my terminal's 'python test.py'. The terminal one outputs autocompletions really well,which means the jedi is in fact work well. So I found the real fault may be that the vscodePy-extension's python interpreter don't fit the numpy's newest version.(the jedi module I used both were jedi that in py-extension.And I used jedi.__file__ to ensure).

It depends on the jedi version you used. We don't necessarily use the latest one.

I have reported it upstream.

for me, this issue fixes after the feb update
ref #99

I feel like this one was solved. Please retry with the latest release. NumPy completions work for me. Haven't tried cv2.
