Is there a way to mark a cell in the ipython notebook readonly using the json format in the ipynb file? (E.g., a cell attribute "readonly":false or some such.) If not, is there a jquery hack to find suppress the double click event in the cell? Yes, Use the steps below Select view on the menubar Point to Cell Toolbar and select Edit Metadata An "Edit Metadata" button will appear at the top-right corner of the cell. Click on that button and edit the json that pops up. Set the editable key to true of false to get the desired effect. There is an extension for IPython that is supposed to that: Read

I've tried multiple animation sample codes and cannot get any of them working. Here's a basic one I've tried from the Matplotlib documentation: """ A simple example of an animated plot """ import numpy as np import matplotlib.pyplot as plt import matplotlib.animation as animation fig, ax = plt.subplots() x = np.arange(0, 2*np.pi, 0.01) # x-array line, = ax.plot(x, np.sin(x)) def animate(i): line.set_ydata(np.sin(x+i/10.0)) # update the data return line, #Init only required for blitting to give a clean slate. def init(): line.set_ydata(np.ma.array(x, mask=True)) return line, ani = animation

I have an ipython notebook which starts with import sklearn When I run it, I get : ImportError: No module named sklearn indeed if I run the following snippet on the notebook, it's not showing scikit_learn: import pip installed_packages = pip.get_installed_distributions() installed_packages_list = sorted(["%s==%s" % (i.key, i.version) for i in installed_packages]) print installed_packages_list However when I run the snippet from command line, scikit_learn is in the list. I thought of a version problem (module installed for one version and not on the other one), bur both on notebook and command

I want to customize my notebook, make it more readable and stylish. So for that, I want to start with centering my headers. Is it possible? You can actually use the markdown mode for the cell and use the normal HTML code, as in <h1><center>Centered text!</center></h1> Not directly with markdown i think, but you can just enter HTML in the markdown cells: <h3 align="center">This is a centered header</h3> Knowing that in jupyter (ipython) notebook markdown cells the title level is identified by the number of # ( # for top level headings or h1, ## for h2, ....), I use the following combination of

I'm using a dark background for ipython. I would like to have sympy expressions pretty-printed with LaTeX. Problem is the current LaTeX font is black. How can I change LaTeX font colors in the ipython terminal? asmeurer You can set the forecolor and backcolor options in sympy.init_printing . For example, to print the equations in blue, use In [1]: init_printing(forecolor="Blue") 来源： https://stackoverflow.com/questions/18257270/control-latex-expression-color-in-ipython-qtconsole
