"The one feature the notebook currently doesn't support as a Frontend is the ability to send data to the Kernel's standard input socket. That is, if the Kernel requires information to be typed interactively by calling the builtin `raw_input` function, the Notebook will be blocked. This happens for example if you run a script that queries interactively for parameters, and very importantly, is how the interactive IPython debugger that activates when you type `%debug` works.\n",
|
||||
"\n",
|
||||
"So, in order to be able to use `%debug` or anything else that requires `raw_input`, you can either use a Terminal Console or Qt Console connected to a Notebook's Kernel as described above.\n"
|
||||
"The Notebook has added support for `raw_input` and `%debug`, as of 1.0."
