Leginon

Hi,

Our RCT bails with a CV module error on when the RCT node gets to the "CV-Stuff" line (see below). I'm hoping someone can help.

We tried recompiling OpenCV according to the following post and it didn't work.
https://emg.nysbc.org/boards/6/topics/2603?r=2604#message-2604
- The recompiled version uses numpy vrs 6 and other parts of our install use vrs 9.
- When I try testing 'detector = cv2.FeatureDetector_create("SIFT")' in python I still get the no attribute 'FeatureDetector_create' error using the newly compiled version.

Error occured on RCT node. Last operation was CV stuff.
