The issue names no files, tests, or dependency entry point. Start by locating Carnets' Python package and dependency setup, then determine whether OpenCV or another image library and Keras can be installed through pip in the supported environment. Done means the selected dependency is installable and usable for the requested machine-learning image workflows.
