Issues getting SIMA to recognize OpenCV

[Matthew Shtrahman]

I recently installed SIMA on Mac OS 10.10.3 as well as all the prerequisites including OpenCV @3.1.0_1 using macports as recommended in the installation instructions. I figured that I would start by working through with the "Complete Example" workflow.py on Tutorial page and I am consistently getting errors when I run the segmentation routines. Specifically:

>>> dataset.segment(segmentation_approach, 'auto_ROIs')

File "/Users/mshtrahman/Library/Python/2.7/lib/python/site-packages/sima/segment/ca1pc.py", line 109, in _clahe
   raise ImportError('OpenCV >= 2.4.8 required')
ImportError: OpenCV >= 2.4.8 required

I installed and reinstalled OpenCV several times as well as installed the legacy version OpenCV 2.4.9 from source code, with no success. Any suggestions or advice you might have would be greatly appreciated.

Thanks,

Matt

Hi Matt,

I think SIMA may require OpenCV version 2.* i.e. not version 3.*

Hope that helps,
Patrick
