Hi, i am having this issue when i am trying to execute the "Recurrent-Visual-Attention". Following is the command i am running

ubuntuml@ubuntu:~/rnn-master$ th examples/recurrent-visual-attention.lua --useDevice 2 --rho 7 --rewardScale 1 --maxEpoch 2000 --maxTries 200 --learningRate 0.01 --sensorDepth 1 --momentum 0.9 --maxOutNorm -1 --batchSize 20 --saturateEpoch 800 --locatorStd 0.11 --uniform 0.1 --hiddenSize '{256}' --unitPixels 13 --glimpsePatchSize 8

Error output

I looked into other issues. there was some issues with rnn , nn version issues. but the latest comments suggest that now version must not be a problem

Hi, I have the same problem, have u solved it

QaisarRajput commented 7 years ago

@XDUSPONGE Yes. if the error you are receiving is the same. make sure you have the libraries dp, nn, dpnn, torchx installed with luarocks install

After that the what you need to do is, to install rnn package but unlike other packages do not install it like luarocks install rnn (apparently there is some version issue)

But install like this luarocks install rocks/rnn-scm-1.rockspec

Hope this solves your problem. do let us know here
