Module 'torch-rnn' not found

[baricks]

Hi,

Newbie here. I'm trying to get densecap running on the pre-trained model but my system can't seem to locate the torch-rnn module. I suspect something's up with the pathways.

I run:

th run_model.lua -input_image imgs/elephant.jpg -gpu -1

This is the error I'm getting:

run this command again: luarocks install https://raw.githubusercontent.com/jcjohnson/torch-rnn/master/torch-rnn-scm-1.rockspec I had the same issue. Perhaps it updates the dependency.

Additionally - I had this error when trying to run the model on files in a folder:

PANIC: unprotected error in call to Lua API (not enough memory)

So, I updated lua with: cd ~/torch ./clean.sh TORCH_LUA_VERSION=LUA52 ./install.sh

and then updated these: luarocks install https://raw.githubusercontent.com/qassemoquab/stnbhwd/master/stnbhwd-scm-1.rockspec luarocks install https://raw.githubusercontent.com/jcjohnson/torch-rnn/master/torch-rnn-scm-1.rockspec

and I could run the model again perfectly.
