Got a small basic question. I use a Mac, and I used to work in .py files with Sublime 3. One of the things I liked was that when Sublime is closed, for a given file in a folder--if I'm looking for a bit of code--I could hit the spacebar and Macs open a quick preview of the .py document.
Now I'm working in Jupyter Notebook and saving everything as .ipynb files. Now I can't hit the spacebar and glance at files--I launch JN from the command land and it's far slower.
I suspect there are quicker ways to open .ipynb files in browser windows, but what I really want to know is is there a way to quickly preview those file contents from my desktop? Alternatively, is there a way to work in Jupiter Notebook but save the files as .py (and later seamlessly reopen in JN), such that I could still use the great old spacebar trick?
Thanks for you patience with a pretty small question :)
It's been a while since the last answer, but just in case anyone else is looking to use Mac Quicklook to preview Jupyter Notebooks .ipynb files, this app does the job:
Jupyter Notebook Viewer - https://github.com/tuxu/nbviewer-app
You can either download the app from that page or install using brew cask
brew cask install jupyter-notebook-viewer
If the preview is not working you should reload quicklook.
Just open a terminal windows and run. It worked for me on macOS High Sierra.
qlmanage -r
Now enjoy quicklook preview for Jupyter Notebook files :)
I had this same question at the weekend.
I came across two things:
a) this project on Github: https://github.com/jendas1/jupyter-notebook-quick-look
and
b) The Jupyter app which allows you to open Notebooks in Finder on the mac: https://github.com/jendas1/JupyterApp
Caveat - I book marked these, but due to other work I have not had time to download, install or test these.
If you do, please let me know how you get on!
As an update to the previous answers, I'd like to recommend nbviewer.js which is a client-side ipynb renderer. You can use it online at https://kokes.github.io/nbviewer.js/viewer.html
In case anyone wants to do the same on linux, you can check this out
nb-viewer which lets you preview Jupyter notebooks with a double click!
Update for the most recent version of MacOS (tested on macOS Big Sur v11.6) & newer brew versions:
To install Jupyter Notebook Viewer - https://github.com/tuxu/nbviewer-app follow these steps:
brew install --cask jupyter-notebook-viewer
Manually start /Applications/Jupyter Notebook Viewer.app using command + open (to allow a third-party app to be started)
qlmanage -r

PyCharm not recognizing .ipynb files:
I installed 'jupyter notebook' using pip3 but whenever I create a jupyter notebook file on pycharm professional, it doesn't recognize it.
Check File Type settings for Jupyter notebooks - ipynb should be assigned to it.
I know this question was asked almost two years ago but for anyone with the same problem going forward, it appears as of Dec. 22, 2022, .ipynb files are only supported in PyCharm Professional:
https://www.jetbrains.com/help/pycharm/jupyter-notebook-support.html
From the link it says, "Available only in PyCharm Professional: download to try or compare editions."
The link suggests DataSpell as an alternative and the trial version is free. DataSpell also supports anaconda, R, and SQL.
I've been using Juptyer Notebook for more than a year now with python3 and I recently saw through the Anaconda Navigator that an update to the 5.7.0 version was available. I installed it but the first Notebook that I tried to launch wouldn't work : I run the most simple expressions such as:
test = [1,2,3]
print(len(test))
It keeps buffering and nothing comes out of this. Additionally, when I try to define a function, the font doesn't become green and bold like always.
Then I tried to go back to the older version, and that didn't work too. Now I'm back with the up-to-date version but still doesn't work.
I'm on a Windows machine and I don't know very much about source code or precise things to look for in this case.
Could you please follow the below steps and share the feedback. It seems that new update installed in a different path.
Step 1:- Get an Anaconda command prompt and run jupyter notebook in it, It will probably won't work, but you could get a detail error message saying what's failing.
Step 2:- After your anaconda update, if that's left over from the older version of Anaconda. The shortcut properties might tell you what it's trying to call - there may be a wrong path to Anaconda or something wrong, so you can go to anaconda desktop shortcut, then right click on it and check the properties. And also run the %appdata% command in windows 'Run' and check the installed anaconda app data directory.
Stop 3:- If the shortcut was the issue. You can manually change the "Shortcut target" (in windows) to the following
Eg: C:\Users\'yourusername'\AppData\Local\Continuum\Anaconda2\Scripts\jupyter-notebook.exe
Previously, I had Canopy installed and at that time, I could simply double click on ipynb files and open them into the browser.
However, later I needed Anaconda and once I installed it, this feature was gone.
Now I just want to be able to simply double click on ipynb files and the file gets open into the Firefox. Is it possible?
I read about this:
nbopen
pip install nbopen
python -m nbopen.install_win
But it didn't solve my problem. I appreciate any help.
Yes, this is possible. Running python -m nbopen.install_win installs the executable nbopen.exe in the Scripts folder of your anaconda directory. For me this is:
PS> (gcm nbopen).Path
E:\Programs\anaconda\Scripts\nbopen.exe
The first line gets the path of the nbopen command (using PowerShell). If you are not using PowerShell you can find your conda directory by right-clicking on any (I)Python executable in your start menu and look at where it links to.
You can then associate the nbopen.exe file with the .ipynb filetype:
Right-click on a .ipynb file.
Click on Properties
Click on the Change button next to "Open With:"
Click on Browse, browse to the path you found out and select nbopen.exe.
Double-clicking on .ipynb files now checks if a notebook server is running and opens the notebook. If no server is running, one is started in the active directory.
Checkout this Firefox plugin. Python Notebook Viewer.
This plugin lets you view/render python notebooks without running notebook server. Once installed, set Firefox as default app to open ipynb files. From now onwards, you can simply open ipynb files by simply double clicking on it!
This saves a lot of time as most of the time developers are just keen on seeing a code. It also saves a hassle of browsing directories in Jupyter Notebook window to reach to a specific file.
If m00am's solution doesn't work and nbopen.exe file doesn't show up then do the following:
Uninstall Anaconda.
Install Anaconda again and make sure you add Anaconda to Windows path during the installation.
Then try m00am's solution again.
This worked for me:)
I need to open a ipython notebook (.ipynb extension file) to look for some work done by a previous colleague. However, I do not have a knowledge of how the python structure works. Can someone guide me on what should be the easiest way to look at the file?
You'll need to install iPython, either on its own or as part of a prepackaged distribution such as Anaconda. You can then open iPython Notebook with your browser and find the notebook of your interest on your drive.
I'm having a lot of trouble getting Eclipse to recognise PyDev when using the PyDev zip file. (I need to use the zip file as the Dev machine does not have internet access).
I have Eclipse installed and have downloaded the PyDev zip. I've Googled a fair bit and tried the following based on suggestions I found:-
Unzipped the .zip into ECLIPSE/helios/dropins and restarted eclipse.
Unzipped the .zip into ECLIPSE/helios/plugins and restarted eclipse.
Neither makes Python appear as a selection in the Eclipse, Window, Preferences.
Helios contains the executable eclipse file I use to load eclipse.
I'm using eclipse in Redhat linux.
One suggestion was to extract the zip over the eclipse plugins and features folders, but I don't see how that would work as the zip just produces a heap of files and no folders.
Any help to get this working would be great.
Just unzipping the Pydev zip file under C:\eclipse\dropins should be enough. So:
1) Unzip the zip file in C:\eclipse\dropins
2) Launch Eclipse
3) Test your installation: Go to Window -> Preferences -> PyDev
I just did this today and a far easier way to do it is to use the built-in installer. Go to Help -> Install New Software and then type pydev in the software filter. Since you already have the zip, if you extract it in the dropins folder, you'll skip the download portion and go straight to installing it.
I have been able to use the zip to install it manually before. I would extract its contents in the eclipse folder overwriting the features and plugins folder. I suggested this to a coworker earlier today and it didn't work for her. She had to download the newest version of eclipse for this method to work. She downloaded the classic version.
I've been playing with PyDev and Eclipse. Reinstalled Eclipse on a fresh machine and unzipped the standard PyDev over it (not the source version) and it worked fine. Did the same thing on the same machine having the problems but in a different location (/home) also worked fine. So it looks like a configuration problem on the machine not a PyDev/Eclipse issue. Sorry for the run around and thanks for the help. Dog.
For whatever it's worth, I was having the same problem running eclipse 3.6 on RHEL 6. When I ran eclipse as myself, I didn't get any PyDev options; however, when I ran eclipse as root, everything showed up. So permissions could be an issue fyi.
Open the eclipse and navigate in the below format of the menu bar of the eclispe
Window > Perspective > Open Perspective and select Pydev. As a result when next time you open eclipse you will be using it with python.Please follow the below screen shot in the link I am Using python 3.7 with eclipse photon ide.
