Instead of  matplotlib inline it is not a python script so we can write like this it will work from IPython import get ipython get ipython   run line magic  matplotlib    inline

This is the case you are using Julia    The analogue of IPython s  matplotlib in Julia is to use the PyPlot package  which gives a Julia interface to Matplotlib including inline plots in IJulia notebooks   The equivalent of numpy is already loaded by default in Julia   Given PyPlot  the analogue of  matplotlib inline is using PyPlot  since PyPlot defaults to inline plots in IJulia

If you include the following code at the top of your script  matplotlib will run inline when in an IPython environment  like jupyter  hydrogen atom plugin      and it will still work if you launch the script directly via command line  matplotlib won t run inline  and the charts will open in a pop-ups as usual    from IPython import get ipython ipy   get ipython   if ipy is not None      ipy run line magic  matplotlib    inline

There are several reasons as to why this wouldn t work   It is possible that matplotlib is not properly installed  have you tried running    conda install matplotlib   If that doesn t work  look at your  PATH  environment variable  does it contain your libraries and python paths   Similar problem on github anaconda

Because line magics are only supported by the IPython command line not by Python cl  use   exec  matplotlib inline   instead of  matplotlib inline

Line magics are only supported by the IPython command line  They cannot simply be used inside a script  because  something is not correct Python syntax   If you want to do this from a script you have to get access to the IPython API and then call the run line magic function   Instead of  matplotlib inline  you will have to do something like this in your script   from IPython import get ipython get ipython   run line magic  matplotlib    inline     A similar approach is described in this answer  but it uses the deprecated magic function   Note that the script still needs to run in IPython  Under vanilla Python the get ipython function returns None and get ipython   run line magic will raise an AttributeError

The syntax     in  matplotlib inline is recognized by iPython  where it is set up to handle the magic methods   but not Python itself  which gives a SyntaxError   Here is given one solution
