MNIST example error #19

Open vcodreanu opened 8 years ago

vcodreanu commented 8 years ago

I'm trying to run the MNIST example and I get this:

[valeriuc@gcn2 examples]$ th mnist.lua

Do you know what the problem could be?

Can you try removing the cached files? We store temporary files in your user directory:

rm -rf ~/.torch

Thanks.

I tried it, but the error persists:

Any ideas?
