what is cv2 python
install cv2 python mac
how to install opencv in pycharm
install cv2 python ubuntu
could not find a version that satisfies the requirement opencv-python
no module named cv2
cv2 version
pip install opencv-python failed

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


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.

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.

I ran into the same problem. One issue might be OpenCV is created for Python 2.7, not 3 (not all python 2.7 libraries will work in python 3 or greater). I also don't believe you can download OpenCV directly through PyCharm's package installer. I have found luck following the instructions: OpenCV Python. Specifically:

  1. Downloading and installing OpenCV from SourceForge
  2. Copying the cv2.pyd file from the download (opencv\build\python\2.7\x64) into Python's site-packages folder (something like: C:\Python27\Lib\site-packages)
  3. In PyCharm, open the python Console (Tools>Python Console) and type:import cv2, and assuming no errors print cv2.__version__

Alternatively, I have had luck using this package opencv-python, which you can straightforwardly install using pip with pip install opencv-python

Good luck!

skvark/opencv-python, Maybe It's did't install by pip. How can I solve this problem? OpenCV Version: 3.0​.0 Pycharm Version: Conmunity Edition 2016.2.3 OS : Windows 7 64bit.

If so, make sure that  In my case I thought I had the same issue too, after installing it it can't resolve anything about the module: but if I actually hit run anyway it works, maybe it has issue to autocomplete because opencv really comes as a compiled library (and for performace reason it makes sense) and doesn't have many python files, I found this comment related to a windows installation:

Copied from the site above the important part:

Download the OpenCV version corresponding to your Python installation from here. In my case, I’ve used opencv_python-3.1.0-cp35-cp35m-win32.whl.

1     pip install "opencv_python-3.1.0-cp35-cp35m-win32.whl"

Additional note: don't forget to change the name of the downloaded file in the command you use. Apparently by installing opencv, you'll have access to cv2 too.

  • If you are on Ubuntu try sudo apt-get install python3-opencv
  • This answer worked for me on Mac OS.
  • You should accept an answer
  • This answer worked for me on Raspberry Pi 3B
  • This is the correct answer to the question see below too - why was flagged as a no answer in the review is beyond me
  • Note that depending on how your python installations are set-up pip install package-name might install it for python3, and you'd need to do pip2 to get installed for python 2.x. pip should match whatever python does from the command line.
