Pain Point #3: Exporting MNIST images as files

We often need to work within the image directly and not as an array vector. This section will guide us through converting our arrays to .png images.

Getting ready

Exporting the vectors to images requires importing the following library:

import image from matplotlib

How to do it...

This section walks through the steps to convert a sample of MNIST arrays to files in a local folder.

Create a subfolder to save our images to our main folder of MNIST/ using the following script:

if not os.path.exists('MNIST/images...
