使用 Conda 在 Python 3.5 上安装 OpenCV

Question

I tried to install OpenCV Conda with Python 3.5.

I read this and also tried the solutions but nothing worked. I guess that this is because OpenCV hasn't been supported by Python 3.5 yet, does it?

Maybe someone of you knows a solution? Or, do I have to use an earlier version of Python (v2.7)?

Answer 1

I have installed OpenCV using python 2.7 version.

You have to use the command conda install opencv in the command prompt.

If you want a particular version of OpenCV mention the version as follows:

conda install opencv=3.0.0

Answer 2

i just use below command, and it works for me. ( windows 10 pro 64-bit, Anaconda 4.6.8, Spyder 3.3.2)

(base) C:\\Windows\\system32> conda install opencv

output like this:

finally, i tested it in IPython console and Spyder editor and run, both of them works fine.

The use of conda install , as posted earlier, is the way I would prefer. However, if it didn't work, you might consider using Homebrew, as outline in this webpage .

## Install latest Homebrew, if haven't already
which brew #command line; check if installed
## Run the line below in command line terminal
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

## Since you already have python3, no installation necessary
## Install gcc
brew install gcc
## Install necessary python packages
sudo pip3 install -U numpy scipy matplotlib scikit-learn scikit-image

## OpenCV3, specific for python 3
## and "register" to your machine
brew install opencv3 --with-python3
ln -s /usr/local/opt/opencv3/lib/python3.5/site-packages/cv2.cpython-35m-darwin.so /usr/local/lib/python3.5/site-packages/
