Installing opencv on Windows 10 with python 3.6 and anaconda 3.6

Question

How to install opencv with python 3.6 and anaconda 3.6?

I tried conda install -c https://conda.binstar.org/menpo opencv3

but i get the following error:

UnsatisfiableError: The following specifications were found to be in conflict:
  - opencv3 -> python 2.7*
  - python 3.6*
Use "conda info <package>" to see the dependencies for each package.

I am using Windows 10 64-bit, with python 3.6, and anaconda 3.6 installed.

Is it even available for python3.6 at the moment or should i rollback my python version to 3.5.*?

Solution 1

open and run the command.

> pip install opencv-python

this single command help's you to install opencv easily.
you can take help from the video link below. video link

From menpo file page, it shows that the OpenCV 3.2 binary there are only for Python 2.7/3.4/3.5 and on linux-64 platform

You may go to the this site to get the exact version you need.

• opencv_python‑3.2.0‑cp36‑cp36m‑win_amd64.whl is the basic one.
• opencv_python‑3.2.0+contrib‑cp36‑cp36m‑win_amd64.whl is the one with opencv-contrib modules such as the text module for binding to tesseract OCR engine and many others.

Both binary are for OpenCV 3.2 with Python 3.6 binding for Windows 64-bit. To install it, 1) download the binary to local drive, 2) open your Anaconda command prompt and 3) type the command below in the directory the binary locates.

pip install opencv_python‑3.2.0+contrib‑cp36‑cp36m‑win_amd64.whl

Hope this help.

I managed to get it working by doing the following:

1. Download and install python3.6 from official python site https://www.python.org/downloads/release/python-360/

2. Download and install Anaconda 4.4.0 from the official anaconda site https://www.continuum.io/downloads

3. Open command line and run: pip install opencv-python

4. Open command line and run: pip install opencv-contrib-python

   I am using Windows 10 and it worked for me.

It's pretty simple..

Install Anaconda 3.6. Check anaconda is added to System Variable Path.

Open CMD and type conda install -c conda-forge opencv. This will install latest OpenCV version available (3.6).

Open IDE editor and try import cv2. It will probably don't work...don't worry.

You have to add cv2 command to editor.

For Eclipse (with PyDev):

Create firs a project and then do the following:

For PyCharm:

cv2 module probably won't work. Go to the Anaconda folder/Lib/site-packages/cv2 and copy the file cv2.cp36-win_amd64.pyd to the site-packages folder. Rename it cv2.pyd

Now try to write a command... cv2.imread(). If auto-completition don't work, try cv2.cv2.imread(). This will work for sure.

I am using Python 3.6.2 and Anaconda 4.3.23 (It should also work with your case).

I did the following:

• Download the Numpy version corresponding to your Python installation from here. In my case, I’ve used numpy-1.13.1+mkl-cp36-cp36m-win_amd64.whl

• Download the OpenCV version corresponding to your Python installation from here. In my case, I’ve used opencv_python-3.3.0-cp36-cp36m-win_amd64.whl

• Now go to the folder where you downloaded these files and run the following:

  pip install numpy-1.13.1+mkl-cp36-cp36m-win_amd64.whl

  pip install opencv_python-3.3.0-cp36-cp36m-win_amd64.whl

Note the Successfully installed … message after each command.

At this point, you should be able to play with OpenCV and Python. Let’s try a small test first. Start the Python interpreter or Jupyter Notebook and write:

import cv2 
print(cv2.__version__)

If everything was correctly installed, you should see the version number of your OpenCV install, in my case this was 3.3.0.
