I am having issues with changing the starting folder of Jupyter notebooks, as I would like to run the notebooks on a shared server. I am running Windows 10. I have already tried several of the options online:
I have tried changing the "Start in" property of the jupyter
shortcut: now the shortcut just quickly opens the terminal, then
immediately closes again and nothing more happens.
I have tried running the "jupyter notebook --generate-config"
command, both in and outside python: in the first case it tells me
that jupyter is not a recognised command, and in the second that
there's a syntax error at notebook.
I have made a .bat file with the instructions of the shortcut ('''C:\Users\USERNAME\AppData\Local\Continuum\anaconda3\python.exe
C:\Users\USERNAME\AppData\Local\Continuum\anaconda3\cwp.py
C:\Users\USERNAME\AppData\Local\Continuum\anaconda3
C:\Users\USERNAME\AppData\Local\Continuum\anaconda3\python.exe
C:\Users\USERNAME\AppData\Local\Continuum\anaconda3\Scripts\jupyter-notebook-script.py
Z:\Test''') but it
simply opens the terminal in python, and nothing more.
If I try to launch jupyter from the anaconda interface it works, and I can also start it from the terminal, but not in any other way.
The "jupyter notebook --generate-config" method, explained well in this answer from #marneylc, worked, I just had to start in the Anaconda Promt, rather than in cmd.
I hope this is the right way of answering my own question...

I am placing a .py file in Jupyter Notebook profile_default/startup folder. It has some problems, I want to debug and see the logs. Is there any way I see the output or logs generated by that file. I am on windows 10. There are a few methods .py file. I am using keyboard module to generate a hotkey whenever the notebook starts. It isn't working for me. Please suggest a good way to at least debug that file. My ipykernel is 5.3.4 and ipython 7.16.1
The easiest way I've found so far is to fire up ipython from your console.
Assuming the error is not specific to how Jupyter starts the kernel, you will see the error with the stacktrace before the ipython shell starts.
If the error is specific to jupyter kernel, use jupyter kernel. It will start the kernel you specify, and drop a log line if there's an error.
I imagine this question is rather silly.
I'm using VS code and Jupyter notebooks within it. Is it possible to have the output sent to the interactive python interpreter instead/at the same time as the output beneath the Jupyter notebook cells? I tried searching, google but failed.
The answer in short is unfortunately 'no'. The Interactive window can be used with the #%% magic line or using the 'Jupiter.execSelectionInteractive' command (⇧ + ↩ on Mac). However, the later is not available in a notebook, only in .py files.
If open a python jyputer notebook in vscode, then try to execute the notebook (so a kernel starts) and realize I need to activate a different environment, there doesn't seem to be a way to switch environments without completely quitting VSCode and coming back in.
If can switch environments in the terminal window or using the environment picker in the lower left, but it there doesn't seem to be a way to quit the current kernel and have it re-launch under the new environment. I've tried using the "Restart Kernel", closing the notebook and re-opening.
Is there a way to do this?
I'm a developer on this extension. The intention was for this feature to function as the Python Interactive Window did, where you could use the VSCode Interpreter picker to change out an open notebook to a new kernel. However it appears that we have a hitch that we shipped with this functionality. There is already an issue open in our github here which I believe that you filed (just going on user name match :)):
https://github.com/microsoft/vscode-python/issues/7862
That will be the right place to track our progress on fixing this, and it's on our immediate backlog.
When I code in jupyter notebook/lab, if I press enter, two new lines will be
generated, like this:
If I press tab, the code hint appears, but the cursor jump to
the next cell, like this:
These two problem appear recently, I have uninstalled all ipython & jupyter
and reinstall, change browser from chrome to firefox, even when I code in
google colaboratory and coursera's deeplearning exercise, except in pycharm.
I find a great tool solved these problem partly--nteract, I can run local jupyter notebook in it, but the online jupyter notebook run in browser remains unnormal.
New in April 6, I finally find it! This is caused by a script of tempermonkey, which called remove-web-limits, just disable it and everything OK!
Been using the safe and easy confines of PyCharm for a bit now, but I'm trying to get more familiar with using a text editor and the terminal together, so I've forced myself to start using iPython Notebook and Emacs. Aaaaand I have some really dumb questions.
after firing up ipython notebook from terminal with the command 'ipython notebook', it pops up on my browser and lets me code. but can i not use terminal while it's connected to ipython notebook server?
after writing my code in ipython notebook, i'm left with a something.ipynb file. How do I run this file from terminal? If it was a .py file, i know i could execute it by tying python something.py from the command line; but it doesn't work if i type python something.ipynb in the command line. And of course, I assume I hit Control-C to quit out of the running server in terminal first? or do I run the command without quitting that? Or am i doomed to test it in iPython and then copy and paste it to a different txt editor like Emacs and save it in a .py file to run it?
what good is the .ipynb file if i can't run it in terminal or outside the iPython Notebook browser? Could I get my code in a .py from iPython Notebook if I wanted to? (i assume I'll be able to easily run it in terminal by tying something.py then)
thanks in advance. I'm still very much trying to figure out how to use this thing and there aren't many answers out there for questions this elementary.
Yes, you can not use the same terminal. Solutions: open another terminal or run ipython notebook inside screen. If you use Windows you might want to take a look into this question
Notebook documents (ipynb files) can be converted to a range of static formats including LaTeX, HTML, PDF and Python. Read more about converting notebooks in manual
Notebooks are great, because you can show other people your interactive sessions accompanied with text, which may have rich formatting. And if someone can run notebook server he can easily reproduce your computations and maybe modify them. Check out awesome notebook on traveling salesperson problem by Peter Norvig as an example of what you can do with ipynb. Or this notebook. More examples are available here
You can run your IPython notebook process in background.
On Unix platforms you can perform that with (note the leading &):
ipython notebook &
Or after a "normal" run, hit [Control+z] and run the bg command
(some lecture).
you can convert .ipynb file into .py file using nbconvert
with Ipython notebook 2.x (some lecture):
ipython nbconvert --to python mynotebook.ipynb
with Ipython notebook 3.x (some lecture):
ipython nbconvert --to script mynotebook.ipynb
.ipynb contains your script AND results AND formatted text.
You can compare it to a literate script (but using "machine programming language").
