Autocomplete in PyCharm for Python compiled extensions

Question

When writing Python code using compiled extensions (the OpenCV Python bindings, for example), PyCharm doesn\'t seem to be aware of their availability. The imports are marked

Answer 1

I have noticed a difference in pycharm behavior depending on the way to import. using:

import cv2

the auto completion doesn't work,

while with:

from cv2 import cv2

auto completion works

Answer 2

I hate to give a "works for me" answer, but maybe the details on my environment will help you identify the problem on your end.

I've never used PyCharm before, but I just did a test on Mac 10.6.6 using PyCharm 1.1.1, with Macports opencv +python26. The autocomplete worked fine for me the first time. I also closed and re-ran PyCharm and was able to autocomplete without doing anything further. I also had no issue with autocomplete for other native extensions I tried like cjson, procname.

.

Perhaps it is a platform-specific issue (Windows?), or a bug affecting an older version of PyCharm?

Answer 3

In my case on OS X 10.8 and PyCharm 3, IDE was automatically picking different installations of Python. I noticed this in Eclipse Pydev, which picked up the one right one and worked as expected. It was not easy to notice the difference between the two: /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/python
