In recent years, the multimedia community has witnessed an emerging usage of deep learning in computer vision, such as image caption\cite{Vinyals_2015_CVPR}, object detection, instance segmentation and etc, and many companies are adopting deep learning into their commercial products. Developing and Deploying a fast and reliable deep learning system is complex and involves labour-intensive works, like image annotation\cite{Ratner_2017}, data and models versioning and etc. To facilitate such a process, we proposed CVFlow, which is a suite of versatile computer vision libraries and toolkits for handling computer vision tasks, including intelligent annotation toolkit, deep learning package manager, models sharing platform and computer vision serving program.
