The Control channel is similar to Shell but operates on a separate socket so that messages are not queued behind execution requests, and have a higher priority. to forward the content of the standard output streams (stdout and stderr). the IOPub channel, which is a one-directional communication channel from the kernel to the client, and is used e.g.the Shell channel, which is a request/reply channel for e.g.Several communication channels exist, such as Jupyter kernels (the part of the infrastructure that executes the user's code) communicate with the rest of the infrastructure with a well-specified inter-process communication protocol. The Jupyter Debug Protocol New message types for the Control and IOPub channels Note: Depending on the platform, PyPI wheels are available for xeus-python, but they are still experimental. Once xeus-python and the debugger extension are installed, you should be all set to use the Jupyter visual debugger! (Support for the debugger protocol in ipykernel is also on the roadmap). The only kernel implementing this protocol, for now, is xeus-python a new Jupyter kernel for the Python programming language. In the back-end, a kernel implementing the Jupyter Debug Protocol (which will be detailed in the next section) is required.Jupyter labextension install debugger front-end will be included in JupyterLab by default in a future release. The debugger front-end can be installed as a JupyterLab extension.Click on the binder link to launch the demo Installation
