ipynb import another ipynb file

Question

Interactive Python  ipython  is simply amazing  especially as you are piecing things together on the fly    and does it in such a way that it is easy to go back   However  what seems to be interesting is the use-case of having multiple ipython notebooks  ipynb files    It apparently seems like a notebook is NOT supposed to have a relationship with other notebooks  which makes sense  except that I would love to import other ipynb files   The only workaround I see is converting my   ipynb files into   py files  which then can be imported into my notebook   Having one file hold everything in a project is a bit weird  especially if I want to really push for code-reuse  isn t that a core tenet of python     Am I missing something  Is this not a supported use case of ipython notebooks  Is there another solution I can be using for this import of an ipynb file into another notebook  I d love to continue to use ipynb  but it s really messing up my workflow right now

There is no problem at all using Jupyter with existing or new Python .py modules. With Jupyter running, simply fire up Spyder (or any editor of your choice) to build / modify your module class definitions in a .py file, and then just import the modules as needed into Jupyter.

One thing that makes this really seamless is using the autoreload magic extension. You can see documentation for autoreload here:

http://ipython.readthedocs.io/en/stable/config/extensions/autoreload.html

Here is the code to automatically reload the module any time it has been modified:

# autoreload sets up auto reloading of modified .py modules
import autoreload
%load_ext autoreload
%autoreload 2

Note that I tried the code mentioned in a prior reply to simulate loading .ipynb files as modules, and got it to work, but it chokes when you make changes to the .ipynb file. It looks like you need to restart the Jupyter development environment in order to reload the .ipynb 'module', which was not acceptable to me since I am making lots of changes to my code.

Run   pip install ipynb  and then import the other notebook as  from ipynb fs full  lt notebook name gt  import    or  from ipynb fs full  lt notebook name gt  import  lt function name gt   Make sure that all the notebooks are in the same directory   Edit 1  You can see the official documentation here - https   ipynb readthedocs io en stable   Also  if you would like to import only class  amp  function definitions from a notebook  and not the top level statements   you can use ipynb fs defs instead of ipynb fs full  Full uppercase variable assignment will get evaluated as well

Please make sure that you also add a   init   py file in the package where all your other  ipynb files are located   This is in addition to the nbviewer link that minrk and syi provided above   I also had some similar problem and then I wrote the solution as well as a link to my public google drive folder which has a working example     My Stackoverflow post with step by step experimentation and Solution   Jupyter Notebook  Import  ipynb file and access it  39 s method in other  ipynb file giving error  Hope this will help others as well  Thanks all

The above mentioned comments are very useful but they are a bit difficult to implement  Below steps you can try  I also tried it and it worked      Download that file from your notebook in PY file format  You can find that option in File tab   Now copy that downloaded file into the working directory of Jupyter Notebook You are now ready to use it  Just import  PY File into the ipynb file

You can use import nbimporter then import notebookName

If you want to import A ipynb in B ipynb write import import ipynb import A  in B ipynb  The import ipynb module I ve created is installed via pip  pip install import ipynb  It s just one file and it strictly adheres to the official howto on the jupyter site  PS It also supports things like from A import foo  from A import   etc

It is really simple in newer Jupyter    run MyOtherNotebook ipynb

Install ipynb from your command prompt   pip install import-ipynb   Import in your notebook file  import import ipynb   Now use regular import command to import your file  import MyOtherNotebook

User · Answer

run YourNotebookfile ipynb is working fine  if you want to import a specific module then just add the import command after the ipynb i e YourNotebookfile ipynb having def Add   then you can just use it  run YourNotebookfile ipynb import Add

The issue is that a notebooks is not a plain python file  The steps to import the  ipynb file are outlined in the following  Importing notebook  I am pasting the code  so if you need it   you can just do a quick copy and paste   Notice that at the end I have the import primes statement   You ll have to change that of course   The name of my file is primes ipynb   From this point on you can use the content inside that file as you would do regularly   Wish there was a simpler method  but this is straight from the docs  Note  I am using jupyter not ipython   import io  os  sys  types from IPython import get ipython from nbformat import current from IPython core interactiveshell import InteractiveShell   def find notebook fullname  path None          find a notebook  given its fully qualified name and an optional path      This turns  foo bar  into  foo bar ipynb      and tries turning  Foo Bar  into  Foo Bar  if Foo Bar     does not exist              name   fullname rsplit      1  -1      if not path          path            for d in path          nb path   os path join d  name     ipynb           if os path isfile nb path               return nb path           let import Notebook Name find  Notebook Name ipynb          nb path   nb path replace                   if os path isfile nb path               return nb path   class NotebookLoader object          Module Loader for Jupyter Notebooks        def   init   self  path None           self shell   InteractiveShell instance           self path   path      def load module self  fullname              import a notebook as a module            path   find notebook fullname  self path           print   importing Jupyter notebook from  s    path             load the notebook object         with io open path   r   encoding  utf-8   as f              nb   current read f   json               create the module and add it to sys modules           if name in sys modules               return sys modules name          mod   types ModuleType fullname          mod   file     path         mod   loader     self         mod   dict    get ipython     get ipython         sys modules fullname    mod            extra work to ensure that magics that would affect the user ns           actually affect the notebook module s ns         save user ns   self shell user ns         self shell user ns   mod   dict            try          for cell in nb worksheets 0  cells              if cell cell type     code  and cell language     python                     transform the input to executable Python                 code   self shell input transformer manager transform cell cell input                    run the code in themodule                 exec code  mod   dict            finally              self shell user ns   save user ns         return mod   class NotebookFinder object          Module finder that locates Jupyter Notebooks        def   init   self           self loaders           def find module self  fullname  path None           nb path   find notebook fullname  path          if not nb path              return          key   path         if path                lists aren t hashable             key   os path sep join path           if key not in self loaders              self loaders key    NotebookLoader path          return self loaders key   sys meta path append NotebookFinder     import primes
