Suppose we have various .ipynb files in different directories.
I know that I wrote some specific code lines in one of these ipynbs.
How can I search in which .ipynb this code was written from Jupyter notebook interface?
Try opening notebooks in visual code and Ctrl+shift+f for searching multiple files.

I am very new to Voila and Jupyter. I understand Jupyter notebook files (i.e. files with extension .ipynb) can be loaded in either Voila server or Jupyter server.
To elaborate, for instance, we have files below in the same folder: -
a.ipynb
b.ipynb
My question is that if it is possible for me only to load "a.ipynb" in Voila? The example is just for purpose of demonstration. We could have a large number of files / folders in the folder.
I have scanned through Voila website but doesn't look like there is any existing feature I can use to support this.
Thank you.
I work with Jupyter Notebooks with VSCode as my editor. I have noticed that my checkpoint files are not being properly saved in the .ipynb_checkpoints folder as should be.
To illustrate, I made a notebook called test.ipynb, and after starting to work on it (added a few lines of code), the following notebooks were autogenerated in the same directory (not in the .ipynb_checkpoints folder):
test-d636f411-dc52-42c3-8fd5-3ff98a144a25.ipynb
test-804fd168-59a6-40f4-bdb1-fcf1b2fe899f.ipynb
test-1dbb5747-9833-40cb-a382-4a42cae0008a.ipynb
This happens with all my notebooks and, as a result, crowds my working space. I keep manually deleting these redundant files (which by the way have no code in them), but I think there may be something wrong with my settings.
Has anyone experienced this before and how did you solve it? Thanks in advance!
I can't reproduce your problem, but it could be an issue with the Jupyter Notebook.
Some people have met this kind of problem, you can refer to this page for more details.
Could you try to install another version of the Jupyter Notebook to make a try?
I have written some Jupyter notebooks using original Jupyter notebook web interface. All notebooks are synced nicely in this way.
But now, I would like to edit my notebooks in the VSCode. But I cannot configure syncing notebook file with its python script.
I tried this using jupytext:
created file jupytext in the folder ~/.config
put the next code into this file:
# Always pair ipynb notebooks to py:percent files
default_jupytext_formats = "ipynb,py:percent"
But no effect!
(Update) Can this be achieved, as a first solution, using VSCode Tasks (I am not used tasks yet)?
May be it possible to run the task with jupytext command if the notebook file is opened/saved/modified?
Currently, VSCode does not support such a function. The Jupyter function in VSCode is provided by a Python extension, which supports us to convert between .ipynb files and .py files in VSCode.
.ipynb files to .py files : Export as python script.
.py files to .ipynb files : Right click, "Export Current Python File as Jupyter Notebook"
I have submitted the requirement you described, and we look forward to the realization of this feature. Giuhub link: How to synchronize the jupyter file and python file of VSCode.
Every time when I try to run a file in the JupiterLab console I get the following message:
ERROR:root:File 'thing.py' not found.
In this case, my file is called thing.py and I try to run it with the trivial run thing.py command in the console. The code is running and it gives me correct results when executed in the console, but I wanted to have it saved, so I put it in a JupiterLab text file and changed the extension to .py instead of .txt. But I get the aforementioned message regardless of which file I try to run. I am new to JupiterLab and admit that I might have missed something important. Every help is much appreciated.
If you're running Jupyterlab you should be able:
to create a new file & paste in your commands
Rename that file to "thing.py"
And then open a console in the same Jupyterlab instance and run that file. Notice that you can see "thing.py" in the file explorer on the left:
Alternatively, you can use the %load magic command in a notebook to dynamically load the code into a notebook's cell.
You might want to understand exactly what a Jupyter Lab file is, and what a Jupyter Lab file is not. The Jupyter Notebooks have the extension, .ipynb.
So anyway, the Jupyter Notebooks are not saved or formatted with python extensions. There are no Jupyter Notebooks or Jupyter Labs ending with the .py extension. That means Jupyter will not recognize an extension having .py, or .txt or .R or etc.... Jupyter opens, reads, and saves files having the .ipynb extension.
Jupyter Notebooks are an open document format based on JSON.
Jupyter can export in a number of different formats. Under the File tab, is the Export feature. The last time I looked there were about 20 different export formats. But there isn't a python or .py export format. A Jupyter file can also be Downloaded. Also under the File tab is the Download feature. This will download a standard text formatted JSON file. JSON files are mostly unreadable unless you've spent years coding JSON.
So there's not much purpose in downloading the Jupyter file unless you are working on a remote server and cannot save your work at that site. And it makes much more sense to save and copy the Jupyter file in its native Jupyter format - that means having the extension, .ipynb . Then just open and use that file on another PC.
Hopefully this should clarify why Jupyter won't open any .py or .txt files.
This is a bit hard to explain so bear with me! Suppose I have a Jupyter notebook in some directory. The only way I know to open it is to click repeatedly through the web based directory structure. Is there a nice way to do this using the mac finder. In other words I would like a simple dialogue box to open from Jupyter to navigate to my notebook.
edit: thanks, I realized that I can start in certain directories, but what if I'm opening a bunch of different notebooks from different directories. It sure would be nice to be able to jump to my favorites easily.
As #GiantsLoveDeathMetal mentions... if you navigate to a specific directory in your terminal and then type jupyter notebook the notebook will open and display in your browser, just the content of that folder.
For example:
$ cd /path/to/the/folder/with/your/notebook.ipynb
$ jupyter notebook
