ipython

问题 Does anybody know how to check the status of the last executed command (exit code) in ipython? 回答1: I assume that you are talking about running commands from IPython using the ! escape: In[1]: !echo hello hello In[2]: Using Google I found the documentation and there is no mention of the exit status of the command being captured anywhere. Using dir() I looked for a variable name that might be holding that information and I didn't find anything. I tried the x = !ls syntax and x gets set to a

问题 I am using the following code to insert an image in Jupyter notebook which is compatible with html conversion: from IPython.display import Image Image(filename="picture.jpg") This works nicely except the fact that it is left aligned and I need it centre/middle aligned. Is there any method that I can set it to be aligned correctly? 回答1: You can set the cell as markdown and use this content: <img src="picture.jpg" width="240" height="240" align="center"/> Then run it. Edit1 Alternatively, you

问题 I want to display 2 PNG images in iPython side by side. My code to do this is: from IPython.display import Image, HTML, display img_A = '\path\to\img_A.png' img_B = '\path\to\img_B.png' display(HTML("<table><tr><td><img src=img_A></td><td><img src=img_B></td></tr></table>")) But it doesn't output the images, and instead only displays placeholders for the 2 images: I tried the following as well: s = """<table> <tr> <th><img src="%s"/></th> <th><img src="%s"/></th> </tr></table>"""%(img_A, img

问题 I´m using the new Jupyter notebook (neé ipython notebook) and the docs indicate that it renders MathJax from a CDN. I have some situations when outside connections are blocked, so I need to configure a local copy of MathJax for all notebooks. How can I accomplish that? 回答1: On Arch Linux, installing 'community/mathjax' solves the problem. 回答2: As of 4.0 mathjax is part of the notebook as a dependency. There is no need for any extra installation. I am currently experimenting with jupyter on a

问题 My question is similar to the one asked here. I have a cell in a jupyter notebook that runs for a long time. I want to run the next cell (variables not dependent on the previous cell) along with the previous one. I am not asking for multiprocessing or sharing jobs across CPUs. I want to run the contents of multiple cells run simultaneously. By default, they run sequentially. It is like running two different notebooks but for the sake of continuity and shared objects, variables I want to run

问题 Can ipython notebook be used when not connected to the internet? My installation doesn't open a web browser tab if not online. Thanks! 回答1: Yes, it should work without needing an internet connection. If a browser tab doesn't open automatically, open a browser and go to the URL it gives you in the terminal where you started the notebook (by default, this is http://127.0.0.1:8888/ ). It uses the 'loopback' network interface, which stays within your own computer. 来源： https://stackoverflow.com
