Description:
When attempting to run "facerec_demo.py" in the opencv samples folder (i.e. /usr/share/opencv/samples/python2) when the python2-numpy package is not installed on the system, user gets an ImportError related to a numpy module. When I install python2-numpy, the program runs correctly. Additional info: package: opencv-samples 2.4.12.2-1 file location: /usr/share/opencv/samples/python2/facerec_demo.py Steps to reproduce: 1. Ensure python2-numpy is not installed on the system. 2. Run "python2 /usr/share/opencv/samples/python2/facerec_demo.py" Program Error Output: ImportError: numpy.core.multiarray failed to import Traceback (most recent call last): File "facerec_demo.py", line 42, in <module> import cv2 ImportError: numpy.core.multiarray failed to import |

Thanks for the report. We actually have that optional dependency
in opencv itself (in fact, I unset optdepends in -samples), but
perhaps it's better to also have it in the samples package. Makes
sense.
