One-liner or short script to run the code inside a Jupyter notebook?
julia-lang,jupyter,ijulia-notebook
Here's what I have written up: using JSON get_code_cells(j::Dict) = filter(x->x["cell_type"] == "code", j["cells"]) function parse_code_cell(c::Dict) buf = IOBuffer() write(buf, "begin\n") map(x->write(buf, x), c["source"]) write(buf, "\nend") src = bytestring(buf) parse(src) end extract_code(cells::Vector) = Expr[parse_code_cell(c) for c in cells] extract_code(j::Dict) = extract_code(get_code_cells(j)) eval_code(j::Dict) = map(eval, extract_code(j)) # get filename, then parse...

Ok, I found the answer. Simply copy the ipython2 file to ipython: cp /usr/local/bin/ipython2 /usr/local/bin/ipython ...
How to manage and communicate with multiple IPython/Jupyter kernels from a Python script?
python,ipython,ipython-notebook,jupyter
A KernelManager deals with starting and stopping a single kernel, and there's a MultiKernelManager to co-ordinate more than one. http://ipython.org/ipython-doc/3/api/generated/IPython.kernel.manager.html http://ipython.org/ipython-doc/3/api/generated/IPython.kernel.multikernelmanager.html Then you can use the .client() method to get a KernelClient instance which handles communications with a kernel: http://ipython.org/ipython-doc/3/api/generated/IPython.kernel.client.html For details of how you communicate with a kernel, see...
django-extensions shell_plus --kernel specify connection file
python,django,ipython,jupyter,django-extensions
For anyone interested, I fixed this by adding a --connection_file option to the shell_plus command in django-extension, which then forwards the filename to the kernel. I can then define my django kernel for Jupyter-hub as the following. { "display_name": "Django", "language": "python", "codemirror_mode": { "version": 3, "name": "ipython" }, "argv":...
Jupyter: how to make simple illustrations
TikZ (prefered solution) If you're already familiar with TikZ the respective magic is probably the best option. To use it, simply clone this repo into your .ipython/extensions directory and load the extension as shown in the example notebook with %load_ext tikzmagic. I just tried with IPython 3.1 and it works...
Open 'ipython notebook' as: IPython notebook vs Jupyter
ipython,ipython-notebook,jupyter
ipython is now called Jupyter so perhaps a different version of Anaconda is installed on the other computer? So Jupyter is what ipython will continue to develop as - they dropped python as it is basically "agnostic": it can load different languages - python 2 or 3, but also R...

Troubles after updating ipython (%matplotlib nbagg)
python,matplotlib,ipython,ipython-notebook,jupyter
I guess this issue is caused by a too old version of matplotlib. Using %matplotlib nbagg with ipython>=3.0 requires matplotlib>=1.4.3 (Note that %matplotlib notebook and %matplotlib nbagg are now synonyms). Updating matplotlib via pip install --upgrade matplotlib will probably fix this issue. See also my issue-7797 on github. Thanks to...
Changing the default port for iPython notebook server / Jupyter
port,ipython,ipython-notebook,anaconda,jupyter
Something is already listening on 80, you cannot bind 2 servers to the same port. Use a proxy that listen to 80, and redirect to your other servers and IPython base on URL, or address. Also don't use 80, use 443, if you are running a public server it should...
How do I add a kernel on a remote machine in IPython (Jupyter) Notebook?
python,ipython,ipython-notebook,ipython-parallel,jupyter
IPython use kernel is a file in ~/.ipython/kernel/<name> that describe how to launch a kernel. If you create your own kernel (remote, or whatever) it's up to you to have the program run the remote kernel and bind locally to the port the notebook is expected.
R not producing a figure in jupyter (IPython notebook)
r,windows-8,ipython-notebook,anaconda,jupyter
I found a solution from the post on this group. Solution I did: I had the most release of R (R 3.2.0) and following the discussion in the above link, I installed R 3.1.3 and copied winCairo.dll from C:\Program Files\R\R-3.1.3\library\grDevices\libs\x64 to C:\Anaconda\R\library\grDevices\libs\x64. Copying winCairo.dll from R 3.2.0 does not work...

How can I see function arguments in IPython Notebook Server 3?
In 1.0, the functionality was bound to ( and tab and shift-tab, in 2.0 tab was deprecated but still functional in some unambiguous cases completing or inspecting were competing in many cases. Recommendation was to always use shift-Tab. ( was also added as deprecated as confusing in Haskell-like syntax to...

~/.ipython/kernels.json is not the right path. And theses files are not ment to be edited by hand. Also the file you have is not valid json, the server will be unable to read it if it was in the right place. use python2.7 -m IPython kernelspec install-self and python3 -m...
Is it possible to speed up interactive IPython Notebook plots by not generating new figures every time?
python,matplotlib,ipython-notebook,interactive,jupyter
Some setup: %matplotlib notebook import matplotlib.pyplot as plt from IPython.html.widgets import interactive from IPython.display import display import numpy as np Create your objects: fig, ax = plt.subplots() ax.set_xlim(0, .25) ax.set_ylim(-2.5, 2.5) ax.set_title('beat frequencies') lnA, = ax.plot([], [], color='r', label='A') lnB, = ax.plot([], [], color='purple', label='B') lnsum, = ax.plot([], [], color='k',...
