I want to update opencv from 3.1.0 to 3.2.0

I run "conda install -c menpo opencv3=3.1.0" to install opencv 3.1.0

when I run "conda install -c menpo opencv3=3.2.0", I got error.

C:\Users\eason>conda install -c menpo opencv3=3.2.0
Fetching package metadata .............


PackageNotFoundError: Package not found: '' Package missing in current win-64 ch
annels:
- opencv3 3.2.0*

You can search for packages on anaconda.org with

anaconda search -t conda opencv3

https://anaconda.org/menpo/opencv3

When I run "anaconda search -t conda opencv3"... enter image description here

I found opencv3=3.2.0 , but I can't install it?

Is anyone helps ? thanks!

The menpo file page shows only OpenCV 3.2.0 for Python 2.7/3.4/3.5 on linux-64 platform is available.

If you are using Python 3.4, you may try this:

conda install -c daleydeng opencv=3.2.0

  • UnsatisfiableError: The following specifications were found to be in conflict: - opencv 3.2.0* -> python ==3.5 - python 2.7* Use "conda info " to see the dependencies for each package. – eason Mar 02 '17 at 01:00
  • I read the menpo file page... I'm using win7...OK,It can't install... Thanks! – eason Mar 02 '17 at 02:40
  • If you can tell you are using 32-bit or 64-bit Windows, Win7 or Win10 doesn't matter, may be someone can help to advise if there is a binary/package fits you. – thewaywewere Mar 02 '17 at 15:04
  • I'm using Win7 64 – eason Mar 03 '17 at 00:21

Just pushed my OpenCV 3.2 binary to github. It compiled with opencv_contrib modules and runs on Win10 64-bit with Python 2.7.

You may have a trial. Good Luck!

  • What are the installation paths of your 1) Anaconda and 2) OpenCV3.2.0? Do you use `conda-env` in your Anaconda setup? – thewaywewere Mar 07 '17 at 09:37
  • You may refer to **Atlas7**'s reply in [http://stackoverflow.com/questions/23119413](http://stackoverflow.com/questions/23119413/how-to-install-python-opencv-through-conda?rq=1). The `cv2.pyd` and `OPENCV_DIR` setup is pretty much the same. The difference is that my `OpenCV 3.2.0` binary with `contrib` modules is complied with VC14 (i.e. Visual Studio 2015) instead of VC12 (i.e. Visual Studio 2013). – thewaywewere Mar 07 '17 at 13:59
  • I tried it. the same result. When updating the cv2 from 3.1.0 to 3.2.0,I got DLL load failed. – eason Mar 08 '17 at 00:43
  • Seems there is some setting conflicts. What are the Windows environment variable settings and.install paths of your OpenCV 3.2, Anaconda/Python 2.7 and ...? – thewaywewere Mar 08 '17 at 06:27
  • Opencv: C:\Program Files\OpenCV 3.2.0 . Windows environment: C:\Program Files\OpenCV 3.2.0\x64\vc14; I think it's right. – eason Mar 08 '17 at 07:15
  • Have you defined this `OPENCV_DIR = C:\Program Files\OpenCV 3.2.0\×64\vc14` and added this `%OPENCV_DIR%\bin` to Windows environment? For `cv2.pyd`, has it been copied to `C:\ProgramData\Anaconda2\lib\site-packages` (per your screenshot above)? – thewaywewere Mar 08 '17 at 08:49
  • Added it ... and got the same result. – eason Mar 09 '17 at 01:16

  1. Open Anaconda terminal
  2. Navigate to the folder in Anaconda main folder which contains Python Scripts
  3. Download the un-offical opencv + contrib binaries from here
  4. In the Anaconda terminal do pip install
