TEChopra1000 opened a new issue #16449: Train Neural Network Python Tutorial - Plot Images code not working 
URL: https://github.com/apache/incubator-mxnet/issues/16449
 
 
   ## Description
   I was not able to get images to plot in **Train the neural network Python** tutorial found [here](http://mxnet.incubator.apache.org/api/python/docs/tutorials/getting-started/crash-course/4-train.html) as the tutorial is written. Some solutions are proposed below.
   
   ## Environment info (Required)
   
   I ran the recommended script but no environment information was returned after the Environment heading. Working on a MacBook Pro.
   
   Package used (Python/R/Scala/Julia):
   ----------Python Info----------
   Version      : 3.7.3
   Compiler     : Clang 4.0.1 (tags/RELEASE_401/final)
   Build        : ('default', 'Mar 27 2019 16:54:48')
   Arch         : ('64bit', '')
   
   ## Steps to reproduce
   (Paste the commands you ran that produced the error.)
   
   1. Follow the commands found in [this tutorial ](http://mxnet.incubator.apache.org/api/python/docs/tutorials/getting-started/crash-course/4-train.html). 
   2. enter code found in code box 3 one line at a time. The issue comes up for me when entering the line `display.set_matplotlib_formats('svg')`. The terminal changes mode after entering this command, and variables defines in previous commands are no longer accessible. 
   3. even when omitting the line above, I get the error about plt not being defined (see solution below). 
   
   ## What have you tried to solve it?
   
   1. to resolve the error message about `plt` not being defined I had to include `from matplotlib import pyplot as plt`
   2. I omitted the line `display.set_matplotlib_formats('svg')` from code block 3
