Could you please elaborate on the steps required to install Mask R-CNN? I'm particularly interested in understanding the prerequisites and dependencies that need to be met before beginning the installation process. Would it be necessary to have a specific version of Python installed? Are there any specific libraries or frameworks that are crucial for Mask R-CNN to function properly? Additionally, is there a preferred operating system for installation, or does it work seamlessly across multiple platforms? Clarifying these points would greatly assist me in navigating the installation procedure for Mask R-CNN.
