Error in forwardbackward() function while training the data

[hardik2396]

After setting up dependencies, on execution of th train.lua -encoder lf-ques -decoder gen -gpuid 0 error as shown in the snapshot below, is raised. I tried on the different PC configurations and the error still persists hence it is not a system specific problem.

I got the same error. I think the error occurs due to change in the module of rnn installed by LuaRocks. Recently, the previous module (https://github.com/Element-Research/rnn) has been deprecated and the new module (https://github.com/torch/rnn) is being used. Try to install the deprecated module and I guess this error will not occur.

Installation steps

git clone https://github.com/Element-Research/rnn.git
cd rnn
luarocks make rocks/rnn-scm-1.rockspec
