Issue Details

Provide a clear description of the problem, including the following key questions:

I install opencv-4.1.0 with python support (python3.7) and use it in some scripts, but autocomplete is wrong for module cv2 For example:

#!/usr/bin/python3
import numpy as np
import cv2

img = cv2.imread('cat.jpeg', 0)

When I set cv2. then all possible variants it is:

bootstrap       f def bootstrap()                                       
config          m module config                                         
load_config_py2 m module load_config_py2                                
load_config_py3 m module load_config_py3                                
numpy           m module numpy                                          
os              m module os                                             
sys             m module sys                                            
 __doc__         i instance __doc__                                      
 __file__        i instance __file__                                     
 __name__        i instance __name__                                     
__package__     i instance __package__

Include steps to reproduce here.

Include description of a minimal test case, including any actual code required to reproduce the issue.

I expect that I see all complition variants for cv2 like imshew, waitKey, imwrite and other.

Include description of the expected behaviour.

Unfortunately, for cv2 I see some not valid functions. But for other modules, like numpy, sys or os all works fine.

Include description of the observed behaviour, including actual output, screenshots, etc.

I couldn't reproduce this with python 3.7.

Your cursor wasn't in a python file when you executed :YcmDebugInfo, so please post that again.

Yes it is my mistake, thank. I already fix that.

Autocomplete for cv2 working on you machine? I also uses python3.7, but it not work for cv2 module (but work with others, like numpy).

Yes, for example, cv2.wkex leaves only waitKeyEx as the suggestion.

Here's my debug info, I think there might be something wrong with your python path:

I think it is not. Paths is right, cv2 module is there. What about .ycm_extra_conf.py? I see you have this, can I look it?

bstaletic commented 5 years ago

Sure, but there's nothing python related in it.

  return { 'flags': [
    '-std=c++17',
    '-I/home/bstaletic/Temp/test/whereami/src',
    '-Wunused-macros'
    ] }
andrejlevkovitch commented 5 years ago

This is c++ settings, right?

bstaletic commented 5 years ago

Right, like I said, nothing python related.

andrejlevkovitch commented 5 years ago

I found how fix problem: need install opencv-python from pip3. Previous, I uses cv2 module, compiled and installed with opencv.

bstaletic commented 5 years ago

Great. In that case, we can close this.
