Launch IPython notebook with selected browser

问题:

I am trying to start IPython with a non default browser (in my case Firefox) and thought I could replicate the replicate the script given in this blog

I am on Windows 7

I put the following code in a file say "module.py"

import subprocess
subprocess.call("ipython notebook --no-browser", shell=True)
subprocess.call([r'C:\Program Files (x86)\Mozilla Firefox\Firefox.exe', '-new-tab', 'http://127.0.0.1:8888/'])

However when I run it from the command line

 python C:\Users\mugabal\Desktop\module1.py

It execute the first line but not the second one (both lines work fine individually)

My question (in a more general term) how can I launch a process and tell it not to highjack the console window?

I apologize in advance if I have overseen an obvious explanation but I looked both in the subprocess documentation and on this platform

----- UPDATE -----

I should have added that I tried to launch IPython with selected browser but could not figure out how to get it work

>ipython notebook --browser='C:\Program Files (x86)\Mozilla Firefox\Firefox.exe'
... 
[NotebookApp] The IPython Notebook is running at: http://127.0.0.1:8888/
...
**[NotebookApp] No web browser found: could not locate runnable browser.**

To be precise, the following command in a Windows command prompt window works as expected:

start firefox 

but

ipython notebook --browser=firefox 

does not work (same error as above).

I had the same problem on windows and got it work this way:

• Create a config file with command ipython profile create default

• Edit ipython_notebook_config.py file, search for line

#c.NotebookApp.browser =''

and replace it with

import webbrowser
webbrowser.register('firefox', None, webbrowser.GenericBrowser('C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe'))
c.NotebookApp.browser = 'firefox'

then it works for me.

Hope it will help you.

On my mac, I got the following command to use Firefox instead of my default Chrome:

jupyter notebook --browser firefox

回答3:

Why not use

--browser=<Unicode> (NotebookApp.browser)
    Specify what command to use to invoke a web browser when opening the
    notebook. If not specified, the default browser will be determined by the
   `webbrowser` standard library module, which allows setting of the BROWSER

This is not a real answer. I just want to share with the less computer savvy what JPG's answer looks like step-by-step. Presumably, on Windows Explorer (screen capture attached below), the file jupyter_notebook_config.py is listed:

In my case, the directory for the file (on top menu of Explorer) was C:\Users\My_name\.jupyter

The second part of the answer can be implemented by simply pasting:

import webbrowser
webbrowser.register('firefox', None, webbrowser.GenericBrowser('C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe'))
c.NotebookApp.browser = 'firefox'

in the space on the space seen on the screen capture below, corresponding to the jupyter_notebook_config.py opened within PyCharm:

... only that I set it up to open in Opera:

import webbrowser
webbrowser.register('opera', None, webbrowser.GenericBrowser('C:\\Program Files (x86)\\Opera\\launcher.exe'))
c.NotebookApp.browser = 'opera'

回答5:

I uncomment this line and change into False, not to make ipython notebook open a web browser at start, so we can point the ipython notebook address in an active web browser.

# Whether to open in a browser after starting. The specific browser used is
# platform dependent and determined by the python standard library `webbrowser`
# module, unless it is overridden using the --browser (NotebookApp.browser)
# configuration option.
c.NotebookApp.open_browser = False

Better still, I pin the address in my Firefox to make it active everytime I open the browser.

回答6:

I set the environment variable BROWSER to the the executable of the browser (in my case Google Chrome), and Ipython Notebook started in the browser I liked.

PS H:\> $env:BROWSER = "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"
PS H:\> $env:BROWSER
C:\Program Files (x86)\Google\Chrome\Application\chrome.exe

I tried what JPG and norfeldt suggested. It worked perfectly on my Windows 7 computer. Here is a copy of the modified section of ipython_notebook_config.py (located under C:\Users\'your username'\.ipython to use Safari as the default browser for notebook. As norfeldt said, please notice the u before 'C:\...)

# c.NotebookApp.certfile = u''

import webbrowser
webbrowser.register('safari', None, webbrowser.GenericBrowser(u'C:\\Program Files (x86)\\Safari\\safari.exe'))
c.NotebookApp.browser = 'safari'

Without coding, you can just set your default browser to Chrome or Firefox etc. It works for my windows system.
