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
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
