luarocks install nn fails

[mainka]

Hi,

A fresh torch install on Ubuntu 16. luarocks install nn fails. Logs attached.

Confirming, tried to run experiments today after reinstalling torch. Same issue.

[gchanan]

"luarocks install torch" followed by "luarocks install nn" works for me.

[mainka]

I followed the procedure described in http://torch.ch/docs/getting-started.html

# in a terminal, run the commands WITHOUT sudo
git clone https://github.com/torch/distro.git ~/torch --recursive
cd ~/torch; bash install-deps;
./install.sh

I confirm that doing luarocks install torch && luarocks install nn afterwards, everything works. Maybe it should be documented somewhere?

[ddurham2]

I get the same error. Linux Mint 18 which is based on Ubuntu 16.04 LTS. But the error is against code that luarocks downloaded o_O.

@mainka Are you saying that after doing that first step of cloning from git, building and installing, and THEN doing a luarocks install of torch was the key? If so, that seems to imply that version of torch from git is not compatible with the version of nn from luarocks.

[ddurham2]

This worked for me too. I guess the nn project has some work to do getting it compatible with the HEAD of torch.

[nicholas-leonard]

working on this.

[ShowLang]

luarocks install torch && luarocks install nn

[SeekPoint]

it works for me

[rabinandan]

May be luarocks install torch && luarocks install nn work. I am also getting error in luarocks install nn but error code is different Installing https://luarocks.org/nn-1.0.4-1.src.rock gcc -O2 -fPIC -I/usr/include/lua5.2 -c lnn.c -o lnn.o lnn.c:4:23: fatal error: nanomsg/nn.h: No such file or directory

                   ^

compilation terminated.

Error: Your user does not have write permissions in /usr/local/lib/luarocks/rocks -- you may want to run as a privileged user or use your local tree with --local. shamin@shamin-System-Product-Name:~$ Whats wrong here?

[shamimsareem]

I want to install nn to use as dependence of lua and torch code.

[SeekPoint]

since pytorch coming, we don't need torch anymore, bye!
