Torch7: Installation Problem: Missing dependency

[omair-kg]

I'm getting the following message while trying to install torch

Missing dependencies for nn:
moses >= 1.0

Error: Could not satisfy dependency: moses >= 1.0

I tried following the advice given here but still get the same message (missing dependency for nn).

Any idea what i should try next? Thanks in anticipation.

I am facing the same issue. I am behind a proxy and figured out the problem is due to proxy. I tried above commands and installed it. On completion gives same problem again. can anyone help in configuring proxy settings of github so it fetches raw.githubusercontent ?

@hemanthkatari97 Have u tried the specific way of install moses? luarocks install --tree /home/xxx/torch/install rockspec/moses-1.6.1-1.rockspec

[hemanthkatari97]

Getting the following error:
luarocks install --tree=/home/edx/torch/install rockspec/moses-1.6.1-1.rockspec
Using rockspec/moses-1.6.1-1.rockspec... switching to 'build' mode

Error: Error fetching file: Failed downloading https://github.com/Yonaba/Moses/archive/Moses-1.6.1-1.tar.gz

Thanks for reply.

@hemanthkatari97 I don't know why you just download it from a browser? And extract it, get into the folder, and install it luarocks make --tree /home/xxx/torch/install rockspec/moses-1.6.1-1.rockspec, I just made a typo, it should be make instead of install

[karthik-govindappa]

Since I was installing torch on my machine for first time, I had no chance to download and install moses via luarocks make rockspec/*. The following method worked for me.

1. Comment out lines having nn, nngraph and cunn in install.sh. Doing so does not install the aforementioned packages.
2. Running ./install.sh should install torch without any errors
3. Now luarocks will be available. Download moses and install it via luarocks make rockspec/*.
4. Go back to install.sh, uncomment the lines and run ./install.sh. All nn packages should be installed now without any errors.

I have tried all the solutions mentioned above, each time I get a message saying
moses 1.6.1-1 is now built and installed in /home/torch (license: MIT <http://www.opensource.org/licenses/mit-license.php>)
But on running ./install.sh in /home/torch I get the exact same error. What is going wrong?

[hemanthkatari97]

@Marauderer97 It is due to proxy. Are you working behind a proxy?

[kamranthomas]

sudo luarocks make *.rockspec try that

@hemanthkatari97 hello, I am facing the same issue. How did you configure the proxy settings to slove this problem? Thanks!

[hemanthkatari97]

Ya you can check the detailed configuration proxy settings required in

I was facing the same issue.
I followed the steps mentioned by shriyashchougule. But was still getting the dependency issue with moses.
Then I ran the ./install.sh with sudo and could complete the installation.

[yonihei]

by using karthik-govindappa's suggestions i managed to install ./install.sh after removing grahp, cunn, nn.

then by using:
luarocks make --tree /home/xxx/torch/install moses-package

finally ./install.sh without comments ran well.

do NOT use sudo anywhere here. it only caused me troubles.
