matplotlib line magic causes SyntaxError in Python script

Question

I try to run the following codes on Spyder  Python 2 7 11      - - coding  utf-8 - -  import numpy as np import pandas as pd   matplotlib inline  import matplotlib pyplot as plt import matplotlib cm as cm  import tensorflow as tf    settings LEARNING RATE   1e-4   set to 20000 on local environment to get 0 99 accuracy TRAINING ITERATIONS   2000          DROPOUT   0 5 BATCH SIZE   50    set to 0 to train on all available data VALIDATION SIZE   2000    image number to output IMAGE TO DISPLAY   10   But I got this error   line 10      matplotlib inline       SyntaxError  invalid syntax    I appreciate if anybody gives me an explanation   P S  the code is from Kaggle competition project  Digit Recognizer

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?

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

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

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

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

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

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

[python] %matplotlib line magic causes SyntaxError in Python script
