opencv3 3.1.0 requires numpy 1.11.0 which breaks cx_freeze #10

Open hschokker opened 8 years ago

As the title states, when installing opencv3 3.1.0 it requires to update numpy to 1.11.0. This version of numpy gives me errors when using cx_freeze to create an executable under windows 7 64 bit. I am running python 3.4 64 bit (anaconda).

If there is a way to install opencv3 3.0.0 I would be helped.

Oh - what is the error exactly? The issue is that our automated Windows build are all shared by a single account and only one build can run at a time. Therefore, have huge build matrices that take a long time to build really starts to hurt the other packages we provide as we end up being stuck waiting for other projects to complete.

Therefore, providing builds for OpenCV for many numpy versions across 3 Python versions becomes prohibitively expensive for the project. You are welcome to build OpenCV yourself using the recipe, or alternatively you could wait for conda-forge to merge in OpenCV 3 where both numpy 1.10 and 1.11 builds will be provided.

I have to type it by hand since logging in batch doesn't work when I get this error:

Traceback (most recent call last): File "setup.py", line 2, in import numpy as np File "C:\Users\myname\AppData\Local\Continuum\Anaconda3\lib\site-packages\numpyinit.py", line 180, in from . import add_newdocs File "C:\Users\myname\AppData\Local\Continuum\Anaconda3\lib\site-packages\numpy\add_newdocs.py", line 13, in

..And similar for these: from numpy.lib import add_newdoc from .type_check import * import numpy.core.numeric as _nx from . import multiarray ImportError: DLL load failed: The specified module could not be found.

I get this error when I installed opencv3 3.1.0 and had the numpy version updated to 1.11.0. I will next try to downgrade numpy to 1.9.3 which worked for me with opencv3 3.0.0 before. (Probably this won't work)
