“Could not find a version that satisfies the requirement opencv-python”

Question

I am struggling with Jetson TX2 board (aarch64).

I need to install python wrapper for OpenCV.

I can do:

$ sudo apt-get install python-opencv
         


        

Answer 1

We were getting the same error.For us, it solved by upgrading pip version (also discussed in FAQ of OpenCV GitHub). Earlier we had pip-7.1.0, post upgrading it to "pip-9.0.2", it successfully installed.

pip install --upgrade pip
pip install opencv-python

Answer 2

It happened with me on Windows, pip was not able to install opencv-python==3.4.0.12.

Later found out that it was due to the Python version, Python 3.7 has some issue with not getting linked to https://github.com/skvark/opencv-python.

Downgraded to Python 3.6 and it worked with:

pip3 install opencv-python

Answer 3

Use this and it will work:

pip install --upgrade pip
pip install opencv-python

Answer 4

I had the same error. The first time I used the 32-bit version of python but my computer is 64-bit. I then reinstalled the 64-bit version and succeeded.

Answer 5

As there is no proper wheel file in http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv?

Try this:(Worked in Anaconda Prompt or Pycharm)

pip install opencv-contrib-python

pip install opencv-python

Answer 6

Install it by using this command:

pip install opencv-contrib-python
