Create confusion matrix in Python for output from NN model

详细信息

Code found at https://github.com/ejlok1/blogpost.io/blob/master/Episode%204/CNN%20-%20Part%203.ipynb, calculates accuracy etc for a dataset, using CNN. I would like additional few lines of code to produce a confusion matrix for the 7 categories (as well as aggregate performance measures), along with a description of what the matrix is showing.
