class nn.SpatialGlimpse has been already assigned a parent class

When I run command th> require 'dpnn' or when I try to run th main.lua --help from feedback networks, I get the following error:

/home/mobeen/torch/install/bin/luajit: /home/mobeen/torch/install/share/lua/5.1/trepl/init.lua:389: /home/mobeen/torch/install/share/lua/5.1/trepl/init.lua:389: /home/mobeen/torch/install/share/lua/5.1/trepl/init.lua:389: /home/mobeen/torch/install/share/lua/5.1/trepl/init.lua:389: /home/mobeen/torch/install/share/lua/5.1/torch/init.lua:102: class nn.SpatialGlimpse has been already assigned a parent class

I have installed

luarocks install rnn
luarocks install dpnn
luarocks install nn
luarocks install cutorch

but still not working.

Having the exact same problem here.

@ahmadmobeen So apparently the problem is with the 'rnn' package. It used to be based on https://github.com/Element-Research/rnn but that package is now deprecated, and rnn is now from https://github.com/torch/rnn. The problem is, that torch's rnn ALSO implements some of the functionalities in 'dpnn', while Element-Research's rnn does not implement these functionalities! Therefore, if you want to use both rnn and dpnn, you have to use the deprecated package of Element-Research for now using:

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

instead of

luarocks install rnn

cause that will install torch/rnn.

Thank you for replying @noodlez04 but when I try to run:
git clone git@github.com:Element-Research/rnn.git

I get the following error:

My bad. Use the HTTPS version, and not the SSH one:
git clone https://github.com/Element-Research/rnn.git
