How to show source code of a package function in IPython notebook

由 ╄→гoц情女王★ 提交于 2019-12-08 15:29:42
问题 For teaching purposes I want an IPython notebook that displays (as output from a cell) the function source code, but I want to be able to reference this in multiple notebooks. Hence I would like to display the function code, in a similar way to using the %psource magic, but appropriately syntax highlighted. This is a similar question to this question, but I want to be able to apply it to a single function within a file, rather than to the complete file at once. Using the suggestion from the

Error “GraphViz's executables not found” when calling GraphViz layout from NetworkX in iPython notebook

问题 I received the error "InvocationException: GraphViz's executables not found, error GraphViz's executables not found" when trying to use the method graphviz_layout in my code. The code works fine when graphviz_layout is replaced by spring_layout. From the throwback exception information, it looks like it calls pydot_layout.

IPython notebook in zc.buildout not using eggs path

由 倖福魔咒の 提交于 2019-12-08 07:40:56
问题 I've build an environment with zc.buildout including IPython script. My problem is simple: if I launch IPython in console, everything is OK and I get all my eggs in sys.path but if I launch IPython notebook, I only get default system path. Is there any way to include all my eggs while starting notebook? Regards, Thierry 回答1: So, I guess somewhere in the notebook startup a process is forked, which means sys.path will get reset and buildout's tricks won't help. I solved the problems as follows,

I am aware of the %whos
