Merge pull request #1946 from tkf/terminal-image-handler Add image message handler in ZMQTerminalInteractiveShell This change introduces several handlers for messages which contain image in ZMQTerminalInteractiveShell. This is useful, for example, when connecting to the kernel in which pylab inline backend is activated. This PR will fix #1575.
