I'm getting the same error. I am able to call -h and -prb and -d successfully.

I am actually unable to do anything

So it's failing at import cv2 and again at if not args.sw and not ocl.compat_ocl_device_available():. Probably a packaging thing (a missing DLL in the package or PATHS weren't set right).

I didn't change much code so I figured I didn't have to test this latest version, but thanks for the report I'll try to get it fixed sometime today. Use the latest "stable" version (0.2.3) for now. If you're getting device detection errors look at #103 (comment) for a fix.

Just pushed a fix (I hope it works). You can download 0.2.4a3 from the Latest Releases page and test it out. I don't have a second Windows machine to test on a clean environment so I mostly depend on user reports.

Update: Never mind, just got a report that it's not working. Hang tight while I try to get this working.
