Training error

[admeliora]

I trained on a 30 MB text file that has been successfully preprocessed with num_layers = 3 and rnn_size = 500. It ran without any issues for around 12 hours, but then I got a write error:

/home/ubuntu/torch/install/share/lua/5.1/torch/File.lua:235: in function 'writeObject' /home/ubuntu/torch/install/share/lua/5.1/torch/File.lua:235: in function 'writeObject' /home/ubuntu/torch/install/share/lua/5.1/nn/Module.lua:188: in function 'write' /home/ubuntu/torch/install/share/lua/5.1/torch/File.lua:210: in function 'writeObject' /home/ubuntu/torch/install/share/lua/5.1/torch/File.lua:235: in function 'writeObject' /home/ubuntu/torch/install/share/lua/5.1/torch/File.lua:388: in function 'save'

Any ideas what the issue might be?
