cv2.samples is missing

[Maosef]

I was trying to run one of the scripts on background subtraction: https://docs.opencv.org/3.4/d1/dc5/tutorial_background_subtraction.html

(maskrcnn_benchmark) C:\Users\pazzu>python
Python 3.7.1 | packaged by conda-forge | (default, Nov 13 2018, 19:01:41) [MSC v.1900 64 bit (AMD64)] :: Anaconda, Inc. on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> cv2.samples
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'cv2' has no attribute 'samples'

Module version is opencv: 3.4.2-py37h40b0b35_0
samples does exist when I install it from pip.

Yea, I don't think we install the samples correctly. There might be a certain flag we would need to specify.

Do you want to try and find it?

The second problem I see is that it would make the package much larger. Personally, I would want to separate it from the main package. Split packages might help with that but cmake+split packages is a little annoying

As an immediate solution: If you are simply learning opencv, they just released a pip installable module. Try that for a bit, then you can probably use the conda-forge build after your "learning" period to install the package on many computers.

Fair enough, I ended up using pip opencv-python and it worked fine.

We would need to enable https://github.com/opencv/opencv/blob/master/CMakeLists.txt#L859
