No completions for opencv-python/cv2 3.4.0.12

[brettcannon]

This is with NumPy 1.14.2 also installed (see microsoft/vscode-python#606 as to why NumPy versions might matter).

It works perfectly fine for me:

• Ubuntu 16.04
• Python 3.5
• cv2 3.4.0
• numpy 1.11.0

Can you please run this code? I suspect that you didn't specify the right environment and jedi doesn't find the library.

[brettcannon]

Yep, we screwed up on this one. Sorry about wasting your time. 😢

[davidhalter]

No problem. :)
