Missing dependency: Numeric

[Mikkel Munch Mortensen]

Binary package hint: python-opencv

I was trying to run the example code from here: <http://www.jperla.com/blog/2007/09/26/capturing-frames-from-a-webcam-on-linux/>

I installed python-opencv, but the module opencv.adaptors wouldn't work, as it tries to import Numeric (which is in python-numeric).

/usr/lib/pymodules/python2.6/opencv/adaptors.py line 66

I don't know what the policy is for package dependencies, but maybe python-opencv should have a dependency on python-numeric?

I'm running Ubuntu 9.10.
"apt-cache policy python-opencv" says:
python-opencv:
  Installed: 1.0.0-6.2ubuntu1
  Candidate: 1.0.0-6.2ubuntu1

Also just ran in to this.

It looks like Numeric USED to be the name for the project which has evolved into NumPy.

Go in to adaptors.py (/usr/lib/pymodules/python2.6/opencv/adaptors.py)
Find: import Numeric
Replace with: import numpy

sudo apt-get install numpy

Hopefully the package maintainer will see this and release a fix

these days python-opencv depends on python-numpy.
