How to covert a file to .gz extension

Question

I am working with MNIST data in ML(for digit recognistion) and I want to convert my 'mnist.pkl' to 'mnist.pkl.gz' because the turtorial I am watching uses that extension.

also if possible please tell me what are those ..... that he has before the file name('.../data/mnist.pkl.gz', 'rb') if you are familiar with it Thank You

Answer 1

The extension .gz indicates that the file was compressed using gzip which you can do by invoking

gzip mnist.pkl

on the command line. The command will remove the original file and replace it with a compressed version named mnist.pkl.gz.

That said, you don't have to compress/decompress the file in your particular case. Just use

f = open('../data.mnist.pkl', 'rb')

instead of

f = gzip.open('../data.mnist.pkl.gz', 'rb')
