How to re-import a jupyter html file? - python

A coworker sent a jupyter notebook converted into html format. I want to edit it, how can I open the html in my jupyter environment?

This is possibly a dublicate of other Question, you might also ask your college to send you the original file, or open the html in your browser and copy the code into a new notebook

You cannot open it directly. It needs to be converted back into an executable .ipynb Jupyter file.
Take a look at this code example to do the conversion:

.ipynb file not displaying properly in GitHub

I've uploaded a .ipynb jupyter notebook in GitHub but it doesn't display the exact same output as I've written in jupyter notebook.
Here's the link to my repo: ipynb file
You need to view the notebook as "rendered blob" not as "source blob". In GitHub, this is done by selecting the second rendering option in the top right:
It is mostly issue with Github backend. Try this way instead uploading directly
Go to --> https://nbviewer.org/
Paste your .ipynb github link here.
You can downlaod or embedded your file directly from here..

File not found when running a file in JupiterLab console

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.

How to directly open Jupyter from cmd instead of copying link

I often use jupyter for classes, and use the commmand python -m notebook to open the notebook. The tab that opens up shows an error, and then I have to copy one of the links in the terminal window instead. Is there a way or a command that I can use so that one of those links automatically opens up?
NOTE: It opens the file location (first address in the picture) and fails, and I use the links below to open jupyter. I want the terminal to open the links directly if possible to save time.
This is the error that I get.
jupyter notebook notebook.ipynb
Taken from this documentation.
It shouldn't matter whether you install it using conda or pip.
Or you can just type jupyter notebook which should open up a your file directory in the browser and let you navigate to the notebook file you want to open.
Edit: For this error, it really is hard without knowing the full context of the commands you are running, the directory you are calling from, and where this file you want to open is located. Make sure you are in the folder that contains your notebook file. If not, you should specify the entire path to the notebook file. Finally, does the command jupyter notebook by itself work?

Open IPython notebooks (*.ipynb) in read-only view (like a HTML file)

Nowadays with more and more IPython notebook files (*.ipynb) around, it is very disturbing every time when I want to peek at some notebook I have to open a server for it, and cannot do it in read-only mode. Due to auto-save I can accidentally change the file when reading it if not in read-only mode.
I hope something like this: ipython notebook mynb.ipynb --read-only would work, but sadly it doesn't (although still it creates a server which I don't really want in read-only view). What I really want is to open an ipynb file like a HTML file for reading; currently it seems a missing view of ipynb file, and now the notebook is more like a black-box or near-binary file alone.
(P.S. I am using Linux/Ubuntu.)
When you change the notebook files' permissions, jupyter's auto-save doesn't touch them:
chmod a-w *.ipynb
Then jupyter goes into read-only mode:
Try this ipynb Viewer. This renders ipython notebook as a static web-page.
Also ypu can convert ipyhton notebook to other formats using
ipython nbconvert --to FORMAT notebook.ipynb.
Refer Convert Ipython notebook to other formats. Using this you can convert ipython notebook to HTML.
You may also want to try nteract app (https://nteract.io)
nteract is a desktop application that allows you to develop rich documents that contain prose, executable code (in almost any language!), and images.
Here you can find more detailed review of the app.
It is completely free and very convenient tool by itself and I use it quite often to see other ipynb files if needed and for quick development.
The best I can suggest - unfortunately still a bit verbose - is using nbconvert to create a HTML version of the file, then opening it with your browser. Below are commands to do this (assuming that your browser is set up as the default program to handle .html files). Just replace yournotebook.ipynb with your real Notebook name.
Linux
jupyter nbconvert --to html yournotebook.ipynb --output /tmp/notebook.html &&
xdg-open /tmp/notebook.html
macOS
jupyter nbconvert --to html yournotebook.ipynb --output /tmp/notebook.html &&
open /tmp/notebook.html
Windows
jupyter nbconvert --to html yournotebook.ipynb --output "%TEMP%\notebook.html" && start "" "%TEMP%\notebook.html"
(Note that if you want to do this in bulk, perhaps in a loop in a script, you'll probably want to modify the commands above to not always use the same filename for the HTML file, to avoid the race condition where the HTML file has been overwritten by the time the browser actually gets round to starting to read it.)
Intellij IDEA (which is also available as free open-source community edition) can render ipynb files as well. In fact it also allows to author notebooks, so it's not just a viewer.
It can be used via file type associations or via the command line launcher (e.g. idea foo.pynb).
I use Github Gist for that. You'll need a Github account.
If you specify *.ipynb file extension there for your content copy/paste, it'll detect it and format as html view. You'll be able even sharing it with someone using link if that's interesting. No tools required other than having a browser.
I've found some glitches in formatting though, mostly with output plots, but it's reasonably rare.
Random example here: https://gist.github.com/Clockware/aa7e01722579841d5888ca83385a5f1d
I was able to read .ipynb files as html in visual code. You would need a python plugin for it which visual code auto detects. Fairly straight forward after that.
This most convenient method to take a peek at jupyter notebooks is by using nb-viewer, with this utility, you will be able to open notebooks (in read-only mode) with a double click.

Opening a .ipynb.txt File

I have got downloaded a file that got downloaded in a format .pynb.txt extension. Can anyone help me to figure how to make it in a readable format?
Attaching a screenshot of the file when i tried opening in python notebook.
What you have on your hands is an IPython Notebook file. (Now renamed to Jupyter Notebook
you can open it using the command ipython notebook filename.ipynb from the directory it is downloaded on to.
If you are on a newer machine, open the file as jupyter notebook filename.ipynb.
do not forget to remove the .txt extension.
the file has a series of python code/statements and markdown text that you can run/inspect/save/share. read more about ipython notebook from the website.
if you do not have IPython installed, you can do
pip install ipython
or check out installation instructions at the ipython website
If you have a unix/linux system I'd just rename the file via command line
mv file_name.pynb.txt file_name.ipynb
worked like a charm for me!
These steps work for me:
Open the file in Jupyter Notebook.
Rename the file: Click File > Rename, change the name so that it ends with '.ipynb' behind, and click OK
Close the file.
From the Jupyter Notebook's directory tree, click the filename to open it.
Try the following steps:
Download the file open it in the Juypter Notebook.
Go to File -> Rename and remove the .txt extension from the end; so now the file name has just .ipynb extension.
Now reopen it from the Juypter Notebook.
I used to read jupiter nb files with this code:
import codecs
import json
f = codecs.open("JupFileName.ipynb", 'r')
source = f.read()
y = json.loads(source)
pySource = '##Python code from jpynb:\n'
for x in y['cells']:
for x2 in x['source']:
pySource = pySource + x2
if x2[-1] != '\n':
pySource = pySource + '\n'
print(pySource)
Below is the easiest way in case if Anaconda is already installed.
1) Under "Files", there is an option called,"Upload".
2) Click on "Upload" button and it asks for the path of the file and select
the file and click on upload button present beside the file.
The trick that works is this:
Open the file with jupyter notebook. It is not going to display properly, don't work.
Click on file > rename and remove the ".txt" attached to the file's name immediately after ".ipynb"
Close the file and reopen it.
Enjoy it.
go to cmd get into file directory and type
jupyter notebook filename.ipynb in my case it open code editor and provide local host connection string copy that string and paste in any browser!done
I faced a similar situation what I did is created a blank .ipynb file via Jupyter and replacted the code in the blank file.
CMD in Windows machine type jupyter notebook
Then Opened new IPY kernal
In the new IPY Kernal went to file>>Download as>> Notebook(.ipynb)
This will create a blank .ipynb file
opened that file in notepad and replaced the code.
I faced a similar issue recently. (Using Linux)
What I did is-
searched for jupyter support in VsCodium(Visual Studio Code)
the package named "ms-python" is the support for jupyter which opens ".ipynb" file.
Click on the second ext in the image
Another way of opening a ".ipynb" file is simply opening it on the jupyter online Jupyter online you can upload your files and continue
Upload the file on Jupyter Notebook with (.ipynb.txt) format.
Single click on the file name.
Rename it.
Click Save.
Works for me as of 9/17/2022
