Automatically run matplotlib inline in IPython Notebook

Question

Every time I launch IPython Notebook  the first command I run is   matplotlib inline   Is there some way to change my config file so that when I launch IPython  it is automatically in this mode

In your ipython config py file  search for the following lines    c InteractiveShellApp matplotlib   None   and    c InteractiveShellApp pylab   None   and uncomment them  Then  change None to the backend that you re using  I use  qt4   and save the file  Restart IPython  and matplotlib and pylab should be loaded - you can use the dir   command to verify which modules are in the global namespace

The setting was disabled in Jupyter 5 X and higher by adding below code  pylab   Unicode  disabled   config True      help           DISABLED  use  pylab or  matplotlib in the notebook to enable matplotlib               observe  pylab   def  update pylab self  change          when --pylab is specified  display a warning and exit        if change  new       warn           backend      s    change  new       else          backend          self log error    Support for specifying --pylab on the command line has been removed         self log error             Please use   pylab 0   or   matplotlib 0   in the notebook itself    format backend            self exit 1    And in previous versions it has majorly been a warning  But this not a big issue because Jupyter uses concepts of kernels and you can find kernel for your project by running below command    jupyter kernelspec list Available kernels    python3     Users tarunlalwani Documents Projects SO notebookinline bin    share jupyter kernels python3   This gives me the path to the kernel folder  Now if I open the  Users tarunlalwani Documents Projects SO notebookinline bin    share jupyter kernels python3 kernel json file  I see something like below      argv        python      -m      ipykernel launcher      -f       connection file          display name    Python 3     language    python      So you can see what command is executed to launch the kernel  So if you run the below command    python -m ipykernel launcher --help IPython  an enhanced interactive Python shell   Subcommands -----------  Subcommands are launched as  ipython-kernel cmd  args    For information on using subcommand  cmd   do   ipython-kernel cmd -h    install     Install the IPython kernel  Options -------  Arguments that take values are actually convenience aliases to full Configurables  whose aliases are listed on the help line  For more information on full configurables  see  --help-all         --pylab  lt CaselessStrEnum gt   InteractiveShellApp pylab      Default  None     Choices    auto    agg    gtk    gtk3    inline    ipympl    nbagg    notebook    osx    pdf    ps    qt    qt4    qt5    svg    tk    widget    wx       Pre-load matplotlib and numpy for interactive use  selecting a particular     matplotlib backend and loop integration  --matplotlib  lt CaselessStrEnum gt   InteractiveShellApp matplotlib      Default  None     Choices    auto    agg    gtk    gtk3    inline    ipympl    nbagg    notebook    osx    pdf    ps    qt    qt4    qt5    svg    tk    widget    wx       Configure matplotlib for interactive use with the default matplotlib     backend          To see all available configurables  use  --help-all    So now if we update our kernel json file to      argv        python      -m      ipykernel launcher      -f       connection file       --pylab      inline        display name    Python 3     language    python      And if I run jupyter notebook the graphs are automatically inline    Note the below approach also still works  where you create a file on below path     ipython profile default ipython kernel config py  c   get config   c IPKernelApp matplotlib    inline    But the disadvantage of this approach is that this is a global impact on every environment using python  You can consider that as an advantage also if you want to have a common behaviour across environments with a single change   So choose which approach you would like to use based on your requirement

The configuration way  IPython has profiles for configuration  located at    ipython profile    The default profile is called profile default  Within this folder there are two primary configuration files    ipython config py ipython kernel config py   Add the inline option for matplotlib to ipython kernel config py   c   get config         Any other configurables you want to set c InteractiveShellApp matplotlib    inline    matplotlib vs  pylab  Usage of  pylab to get inline plotting is discouraged   It introduces all sorts of gunk into your namespace that you just don t need    matplotlib on the other hand enables inline plotting without injecting your namespace  You ll need to do explicit calls to get matplotlib and numpy imported   import matplotlib pyplot as plt import numpy as np   The small price of typing out your imports explicitly should be completely overcome by the fact that you now have reproducible code

Further to  Kyle Kelley and  DGrady  here is the entry which can be found in the   HOME  ipython profile default ipython kernel config py  or whichever profile you have created   Change    Configure matplotlib for interactive use with the default matplotlib backend    c IPKernelApp matplotlib   none   to    Configure matplotlib for interactive use with the default matplotlib backend  c IPKernelApp matplotlib    inline    This will then work in both ipython qtconsole and notebook sessions

I think what you want might be to run the following from the command line   ipython notebook --matplotlib inline   If you don t like typing it at the cmd line every time then you could create an alias to do it for you
