Hi,

I tried installing OpenCV-2.4.10 for Python-3.4.1 (Anaconda distribution) for Windows-7, 64-bit from the source.

I used CMake and Visual Studio 2012. The whole process went well with no errors in building ALL-BUILD and INSTALL projects. However, I don't see the cv2 module working in Python yet. Is there something more I need to do before I can import the cv2 module in Python? Any help is highly appreciated.

The log file CMakeErrors.log is attached for troubleshooting. I can't attach a log file, so I am cutting and pasting the content of the CMakeError.log:

can you check the cmake-output again ? maybe it got disabled for one or the other reason.

just edit your question, paste it there, and then let's throw out the parts unnessecary, i guess.

"Could the errors in these builds be the reason for this problem" - yes, most likely.

i.e, if it does not find a valid numpy install, it will just disable the python bindings, and everything will compile and install without any visible error

I am attaching the CMakeErrors.log file. Could you please take a look at it and tell me what is missing? I am attaching the file under my main question above

Did anybody get a chance to diagnose what the problem might be? Could somebody please suggest who might be the right person to clarify this issue I am facing?
