Issue submission checklist
- This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
- I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
- The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")
- I'm using the latest version of
opencv-python
