OpenNMT not found - google colab

[mtyrolski]

Hi, I am trying to use im2text on google colab and there is a problem with path to opennmt

OpenNMT not found. Please enter the path to OpenNMT: 	 
/content/Im2Text/opennmt
Error: opennmt not found in the specified path!

how can I fix it?

Is the folder there then? Can you try

! ls /content/Im2Text/opennmt

and see if it's there?

[da03]

btw, did you install lua-torch on colab youself? I don't think colab comes with lua-torch, but maybe I'm wrong.

[mtyrolski]

Yes @da03, I have under !ls /content/Im2Text/opennmt everything from https://github.com/OpenNMT/Im2Text/tree/master/opennmt
Also, I have installed lua-torch on colab myself. It was weird because I had to compile some sources but it seems that it is installed.

%cd /content/
!git clone https://github.com/nagadomi/distro.git torch --recursive
import os
os.chdir('./torch/')
!bash install-deps
!./install.sh
!. ./install/bin/torch-activate

and then
!/content/torch/install/bin/luarocks list

!ls you mentioned gives results below:

/content
Constants.lua  init.lua		  ModelSelector.lua  SeqTagger.lua  translate
data	       LanguageModel.lua  modules	     tagger	    utils
Factory.lua    Model.lua	  Seq2Seq.lua	     train

so it seems that it works

[da03]

Hmm weird, can you directly try

require 'opennmt.init'

in th?

[da03]

such as th -e 'require opennmt.init' and see what's the error msg.

[mtyrolski]

Ok, tried !/content/torch/install/bin/th -e 'require opennmt.init' and got: attempt to call a nil value

[da03]

Hmm it might be due to the opennmt installed in rocks, can you remove /root/.luarocks/lib/luarocks/rocks/opennmt? Like by

!rm -rf /root/.luarocks/lib/luarocks/rocks/opennmt

[mtyrolski]

Yes, I tried that but unfortunately it didn't fix the problem :/
