Re: [spyder] trouble importing openCV on OS X

[Carlos Córdoba]

Hi Daniel,

Probably the best way to do what you want is to change your python
interpreter instead of PYTHONPATH. To do it, you have to go to

Tools > Preferences > Console > Advanced Settings > Python executable

and use the button to the right to select the interpreter where you
installed OpenCV (which seems to be your system's python).

The reason is OpenCV is a shared library which surely is linked against
the python version where it is installed.

Cheers,
Carlos

Hi Carlos,

Thanks for your advise! 

Actually it worked only partly: I was able to import opencv via the console after changing it to my systems's python (v. 2.7.2) and it works fine to run scripts out of the editor. But if i use the console, to call a function, Spyder crashes as soon as I type a open bracket '(' . For example, the autocompletion works fine till 'cv.LoadImage' but as soon as I type '(' it crashes.

I don't know if it's my fault how I installed OpenCV, but I couldn't get it working all day long.  

But don't worry to much, since I have to start working on my project really soon, I will try another IDE in the meantime.

But thank you very much for your help,

Daniel

I can confirm this issue. But it seems related to any dll (.so in this case). 

Auto-completion works, but spyder crashes on the first open bracket '('. 

Strangely enough, it doesn't crash when one or more blank characters are written before '(', e.g. myModule.myMethod ( ... ).

Has anyone looked into this since the last post ?

Thanks,

Thomas
