Pycharm/Python OpenCV and CV2 install error

Question

I've been trying to install both OpenCV and cv2 from both Pycharm and from the terminal as suggested using:

pip install --user opencv pip install --user cv2 

but I'm getting the following error for them:

Collecting opencv   Could not find a version that satisfies the requirement opencv (from versions: ) No matching distribution found for opencv 

and

Collecting cv2   Could not find a version that satisfies the requirement cv2 (from versions: ) No matching distribution found for cv2 

How can I fix these and install the packages properly? I'm using python 3.4.

Answer 1

You are getting those errors because opencv and cv2 are not the python package names.

These are both included as part of the opencv-python package available to install from pip.

If you are using python 2 you can install with pip:

 pip install opencv-python 

Or use the equivilent for python 3:

pip3 install opencv-python 

After running the appropriate pip command your package should be available to use from python.

Answer 2

This the correct command that you need to install opencv

pip install opencv-python 

if you get any error when you are trying to install the "opencv-python" package in pycharm, make sure that you have added your python path to 'System Variables' section of Environment variables in Windows. And also check whether you have configured a valid interpreter for your project
