Only one image comes out of the 9 x9 plot even though `data_augmenter()` passes the tests

@anon57530071 Thanks for writing. I think there are two issues happening:

  1. The images appear identical (not even slightly the same) – I also opened up another thread on this here
  2. the for loop in that plot appears to only be plotting the same augmented image 9 times, which was my main question here. I thought maybe I was missing something and wanted to ask.
