matplotlib python inline on/off

由 心已入冬 提交于 2019-11-26 20:18:23
问题 If I start an ipython notebook with matplotlib inlined, is there a way to subsequently plot a figure so that it shows in the "standard", non-inlined, way, without having to reload the notebook without the inline command? I'd like to be able to have some figures inlined int he notebook, but others in the traditional interactive mode, where I can zoom and pan. 回答1: You can switch the matplotlib's backend by %matplotlib <backend> . To switch back to your system's default backend use %matplotlib

Thanks, 回答1: JMann's solution didn't work for me.

Converting to (not from) ipython Notebook format

由 天大地大妈咪最大 提交于 2019-11-26 18:49:08
问题 IPython Notebook comes with nbconvert, which can export notebooks to other formats. But how do I convert text in the opposite direction? I ask because I already have materials, and a good workflow, in a different format, but I would like to take advantage of Notebook's interactive environment. A likely solution: A notebook can be created by importing a .py file, and the documentation states that when nbconvert exports a notebook as a python script, it embeds directives in comments that can be

How to pickle or store Jupyter (IPython) notebook session for later

由 百般思念 提交于 2019-11-26 18:46:53
问题 Let's say I am doing a larger data analysis in Jupyter/Ipython notebook with lots of time consuming computations done. Then, for some reason, I have to shut down the jupyter local server I, but I would like to return to doing the analysis later, without having to go through all the time-consuming computations again. What I would like love to do is pickle or store the whole Jupyter session (all pandas dataframes, np.arrays, variables, ...) so I can safely shut down the server knowing I can

由 浪子不回头ぞ 提交于 2019-11-26 16:33:56
问题 Is it possible to hide the index when displaying pandas dataframes, so that only the column names appear at the top of the table? This would need to work for both the html representation in ipython notebook and to_latex() function (which I'm using with nbconvert). Ta. 回答1: Set index=False For ipython notebook: print df.to_string(index=False) For to_latex: df.to_latex(index=False) 回答2: As has been pointed out by @waitingkuo, index=False is what you need. If you want to keep the nice table
