问题 I want to send alerts if a long running cell fails, but I don't want to try/except because then I will send needless messages when I am looking at the error. Is there a way to do this? Desired workflow: 1) run status=train() cell 2) see no error in first 15 seconds 3) execute next cell send_alert('done or error') that will execute regardless of the outcome of cell 1. 4) Go do something else Here is a one cell solution that is annoying to code every time: try: start = time.time() train(...)

问题 I'm a bit embarrased to even ask this, but I need to be 100% sure: Does basic usage of a jupyter notebook (running on localhost:8888) trigger any web traffic? I've found it surprisingly hard to find good info on this in the docs or elsewhere. 回答1: If you are just running localhost:8888, and accessing it from your own computer, then no you are not actually generating web traffic, since you can access it even when you have no internet connection. There will still be traffic when you interact

问题 I found similar questions but none relate to my issue in MacOS Showing all possible methods on Jupyter notebook how to show all methods that i can choose in ipython notebook? Many people didn't find those answers useful in MacOS as you can see in the comments. I'm trying to use . + tab to display all the possible methods any initialized object in Jupyter notebook like this: (example image of a list object for context) and none will show up. But in memory variables can be shown. I'm launching

问题 I have some experience with Jupyter Notebook tweaking, but not with JupyterLab. Basically, I want to add a subset of commands to a side tab. Let's say I've registered the command "sample" under the heading "DTLA" function addCommands(app: JupyterLab, tracker: ICommandPalette): void { const category = 'DTLA'; let command = CommandIDs.sample; app.commands.addCommand(command, { label: 'sample', execute: () => { console.log('hellow!'); } }); tracker.addItem({ command, category }) } /** * The

问题 I was just wondering, if there's some way how to automatically save the content of the cell (including the cell output) to a PNG/PDF/JPG/GIF. I'd be happy with any of the alternatives. For documentation purposes I'd like to save the state of a VBox/Hbox containing multiple iPython Widgets. There are many possible combinations of the widgets settings, I can iterate over these settings with my code, but I'd like the corresponding visual setting of the widgets to any of the possible above

问题 This may sound like a silly question, but how do I make use of the autoclose brackets in Jupyter notebook? For example, when I type print( Jupyter notebook auto-closes the brakets print() and places the cursor inside. Then I could type the argument, say print(1 + 1) now my cursor is between the second 1 and the right bracket ) . What is the key to navigate to the right of ) ? Of course I can press End or → or even ) to achieve this, but it does not seem to save time, which is the purpose of
