How to load an existing ipython notebook?

Question

I'm missing something really obvious here but I want to load an existing .ipynb file in my own ipython session. I've tried the following:

$ ipython dream.ipynb 
---------------------------------------------------------------------------
NameError Traceback (most recent call last)
/home/me/develop/deepdream/dream.ipynb in <module>()
 33 {
 34 "cell_type": "code",
---> 35 "collapsed": false,
 36 "input": [
 37 "# imports and basic notebook setup\n",
NameError: name 'false' is not defined

(Google's deepdream notebook) but the json syntax isn't good? I am using the ipython from Anaconda 2.3.0, python 3.4.0 and ipython qtconsole 3.2.0.

• Mikko Ohtamaa: 2024 update: This happens for me if I try to use ipython with Python's multiprocessing module. Jupyter notebook and Visual Studio code are fine. More here: stackoverflow.com/q/77453594/315168

Answer 1

You must start ipython notebook, otherwise ipython tries to execute dream.ipynb as though it were a file containing Python code:

ipython notebook dream.ipynb

Answer 2

You should try to launch an ipython notebook server via ipython notebook, i.e. specifically this command and not the name of the notebook, and to simply load the specific notebook from your webbrowser.

Answer 3

It's better to use jupyter notebook dream.ipynb.

The ipython notebook command will be deprecated in the future.
