[FIXED] Access OpenCV documentation in spyder

Issue

I have Python 2.7.9 and OpenCV 3.1.0 installed on a Windows System. I'm using Spyder 2.3.2 and would love to access documentation for OpenCV in the IDE, however using Ctrl+I on cv2 functions/objects only shows No documentation available.

According to this question, OpenCV documentation should be available since Spyder 2.3.1.

Do I need to install additional modules, copy some files or update packages? If I need to upgrade Spyder, how do I do that? (it seems to be part of my pythonxy installation and the python setup on windows often seems so fragile that I'm hesitant to mess around with it)

Solution

Support for Jedi in Spyder was added in Spyder 2.3.3, released more than two years ago. Jedi is the library used to get completions and documentation from compiled modules like OpenCV.

The latest Spyder version is 3.1.0, which has better integration with Jedi, so I recommend you to update to that version instead.

However, I don't know how to do it using PythonXY, sorry. You should use the Anaconda distribution instead, which is more up to date than PythonXY.
