MNIST example error

[vcodreanu]

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

[valeriuc@gcn2 examples]$ th mnist.lua  
/hpc/sw/torch7-2016.03.10/bin/luajit: cannot open </home/valeriuc/.torch/dataset/3015872663> in mode r  at /home/vc0057/torch/pkg/torch/lib/TH/THDiskFile.c:640

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:
