Hi there,

Just found this rework of the awesome char-rnn and I think it would be very useful in my case. I tried using it but after the installation I got some errors.

I did

th train.lua -gpuid -1

on a debian and got this is the error

/home/deep/torch/install/bin/luajit: /home/deep/torch/install/share/lua/5.1/trepl/init.lua:389: /home/deep/torch/install/share/lua/5.1/trepl/init.lua:389: /home/deep/torch/install/share/lua/5.1/trepl/init.lua:389: module 'cudnn' not found:No LuaRocks module found for cudnn no field package.preload['cudnn'] no file '/home/deep/.luarocks/share/lua/5.1/cudnn.lua' no file '/home/deep/.luarocks/share/lua/5.1/cudnn/init.lua' no file '/home/deep/torch/install/share/lua/5.1/cudnn.lua' no file '/home/deep/torch/install/share/lua/5.1/cudnn/init.lua' no file './cudnn.lua' no file '/home/deep/torch/install/share/luajit-2.1.0-beta1/cudnn.lua' no file '/usr/local/share/lua/5.1/cudnn.lua' no file '/usr/local/share/lua/5.1/cudnn/init.lua' no file '/home/deep/.luarocks/lib/lua/5.1/cudnn.so' no file '/home/deep/torch/install/lib/lua/5.1/cudnn.so' no file '/home/deep/torch/install/lib/cudnn.so' no file './cudnn.so' no file '/usr/local/lib/lua/5.1/cudnn.so' no file '/usr/local/lib/lua/5.1/loadall.so' stack traceback: [C]: in function 'error' /home/deep/torch/install/share/lua/5.1/trepl/init.lua:389: in function 'require' train.lua:37: in main chunk [C]: in function 'dofile' ...deep/torch/install/lib/luarocks/rocks/trepl/scm-1/bin/th:150: in main chunk [C]: at 0x00405d50

So I tried to do this

luarocks install cudnn

and this is the error:

Any help with this?

Thanks

I encountered this problem as well. It encounters the error on line 37 of train.lua which is: local SDRNN = require 'model.SDRNN'

This variable is only used if your model type is set to 'sdrnn'. I got around this by just commenting out line 37 since I plan to only use LSTM anyways.
