EOF Error

When I try to run this snippet, I am getting an EOFError.

images = mnist.train_images()

# scipy.misc.toimage(scipy.misc.imresize(images[0,:,:] * -1 + 256, 10.))

Tracebacks are:

check what tempfile.gettempdir() returns, and that’s where the temporary files are. The names are train-images-idx3-ubyte.gz and similar, *-idx3-* should detect them.

Oh god, thank you so much!

It is fixed. I found them in my C:\Users\User\AppData\Local\Temp folder and the zips there were incomplete/corrupted (?). Deleting them solved the issue.
