storing MNIST data file and results image

[lonnietc]

Hello,

I have recently come across your Python implementation of SOINN and as I am not too good yet with Python, I am wondering if there is a way to adjust the code so that it only downloads the MNIST samples data file one time and stores it locally so that I do not have to keep downloading it with each test?

Also, I was able to generate visualization of the image for the MNIST data as shown on your github site, but do not know how to interpret the our put since the image does not show any useful error for each test cluster and am not sure what the output within my Debian Linux console is relaying in that there seems to be no explanation in the README

I am trying to determine the accuracy and error associate with the training set and test set which is why I would like to have them in 2 different image files or some way to let me find the accuracy of your implementation.

Any help that you could provide would be greatly appreciated.
