imagezmq has been tested with:
- Python 3.5, 3.6, 3.7 and 3.8
- PyZMQ 16.0 and 17.1
- Numpy 1.13 and 1.16
- OpenCV 3.3 and 4.0
- Raspbian Buster, Raspbian Stretch and Raspbian Jessie
- picamera 1.13 (used to capture images for the tests)
- imutils 0.4.6 and 0.5.2 (used to capture images from PiCamera)
OpenCV is challenging to install. I recommend using the installation instructions at PyImageSearch. Adrian Rosebrock's PyImageSearch blog and books are great resources for learning about and installing OpenCV on Raspberry Pi's, Macs and Linux computers.
