# ipython-client
Notes about ipython backend and client
On a Mac, ipython uses the default backend `MacOS`
Spawning a server `ipython kernel` and connecting, the backend is still `MacOS`
Connecting via ipython client, code or Jupyter, this changes to
`module://matplotlib_inline.backend_inline`
The Jupyter commands:
* `%notebook inline` -> `backend=module://matplotlib_inline.backend_inline`, low res embedded PNG image
* `%notebook notebook` -> `backend=nbAgg`, live figure widget with buttons, probably related to ipython.Displays
by default it is `%notebook inline`
```
% ipython kernel
NOTE: When using the `ipython kernel` entry point, Ctrl-C will not work.
To exit, you will have to explicitly quit this process, by either sending
"quit" from a client, or using Ctrl-\ in UNIX-like environments.
To read more about this, see https://github.com/ipython/ipython/issues/2049
To connect another client to this kernel, use:
--existing kernel-71888.json
```
```
% ipython --existing kernel-71888.json
```

%notebook widget
seems to be the same as %notebook ipympl
%matplotlib --list
On Colab is agg by default
Each cell ends with an implicit show. The current axes is cleared, plt.gca()
