Problem with Torch

[jmsellier]

Hello Everyone,

I tried to run char-rnn on my computer but I have a strange problem. First of all, I tried to install Torch by following the instructions on their website:

sudo curl -s https://raw.githubusercontent.com/torch/ezinstall/master/install-all | bash

Despite I am using "sudo", at some point (after a lot of downloading and compiling) the installation script (or whatever it was) complained about having not enough permission to install and got stuck. I stoped it manually and since I could still access Torch by typing:

luajit -ltorch

I thought everything was all right. But now, if I do:

luajit -ltorch train.lua -gpuid -1

this is what I get:

luajit: ./util/CharSplitLMMinibatchLoader.lua:14: attempt to index global 'path' (a nil value) stack traceback: ./util/CharSplitLMMinibatchLoader.lua:14: in function 'create' train.lua:110: in main chunk [C]: at 0x0804c9e0

Since I am no expert of LUA, I have no idea how to proceed. Can someone help me?

MANY thanks in advance!!

JM

Have you tried using the command th rather than luajit?

This error almost certainly means that you somehow haven't followed the instructions for installing Torch in full: http://torch.ch/docs/getting-started.html#_

[jmsellier]

Yes, I tried and it tells me that the command th does not exist.

[soumith]

hey @jmsellier that command you quoted does not appear anywhere on our website. We never recommend "sudo" when installing torch at the moment.

I suggest you clean up the installation using this script: https://raw.githubusercontent.com/torch/ezinstall/master/clean-old.sh

After that, if you use the instructions on our website, you should be okay.

[jmsellier]

Thanks for your help!

I utilized your clean-old script and then I followed the instructions on this page:

http://torch.ch/docs/getting-started.html#_

I had no problem with running the following commands:

curl -s https://raw.githubusercontent.com/torch/ezinstall/master/install-deps | bash git clone https://github.com/torch/distro.git ~/torch --recursive

But when I did:

cd ~/torch; ./install.sh

I got a lot of stuff and then the following error/message (final part):

...

Any idea on how to fix it? Am I doing something wrong?

Thanks!

[soumith]

@jmsellier I think you are running this in a virtual machine. Can you use this command for install:

TORCH_LUA_VERSION=LUAJIT20 ./install.sh

[jmsellier]

I tried your suggestion but it did not work.. and, yes, I am trying to install it in a virtual machine. Do you think this could be the problem?

[jmsellier]

Before I can try the suggestion above I still need torch to be installed on my virtual machine (many thanks anyway). I tried the following new things:

TORCH_LUA_VERSION=LUAJIT20 ./install.sh TORCH_LUA_VERSION=LUAJIT21 ./install.sh TORCH_LUA_VERSION=LUAJIT51 ./install.sh TORCH_LUA_VERSION=LUAJIT52 ./install.sh

and every time I get the following message:

Updating manifest for /home/sellier/torch/install/lib/luarocks/rocks dok scm-1 is now built and installed in /home/sellier/torch/install/ (license: BSD)

gcc -O2 -fPIC -I/home/sellier/torch/install/include -c readline.c -o readline.o readline.c:7:31: fatal error: readline/readline.h: No such file or directory compilation terminated.

Error: Build error: Failed compiling object readline.o

Any clue? MANY thanks!

[hughperkins]

install readline headers? On redhat, this is readline-devel, and on ubuntu it is libreadline-dev , I think.

[hughperkins]

Odd though, normally this is installed by install.sh. I reckon you shoud provide the full install.sh output. Actually, last time this happened, I think it was missing gfortran.

[jmsellier]

I installed the libreadline-dev library and things have improved. Now I can proceed further although at the end I still have an error. Please find it below:

Many many thanks for helping!

[hughperkins]

well, I reckon you're missing libssl-dev ;-)

[hughperkins]

Question: did you first run https://raw.githubusercontent.com/torch/ezinstall/master/install-deps ?

wget https://raw.githubusercontent.com/torch/ezinstall/master/install-deps
bash install-deps

(Edit: hmmm, seems that install-deps doesnt actually install libssl-dev, at least not directly anyway)

[jmsellier]

I installed openssl and then I ran the install-deps script but no luck.. I still get the same error..

[hughperkins]

did you install libssl-dev? ie, sudo apt-get install -y libssl-dev ?

[jmsellier]

I installed libssl-dev and libzmq. I now get a different error:

MANY thanks for helping!

[hughperkins]

I reckon you are missing a bunch of dependencies. Also, I think you used an out of date installation script initially. Can you try:

• rename ~/torch to ~/torch.old
• install torch using the instructions at http://github.com/torch/distro

(In the specific though, I guess you'r emissing lzmq development libraries, but it seems you are misisng tons of libraries...; by the way what OS are you using?)

[jmsellier]

I have used the instructions in that link too and it did not work. I am running Xubuntu in a virtual machine. If this represents a problem, I will use a native GNU/Linux machine then.. Anyway, thanks for your help!

[hughperkins]

Hmmm, well, I'm using xubuntu too :-) though not in a vm. However, my installation path was:

• first installed standard ubuntu 14.04
• then installed xfce4-[something]
• ... therefore I already had a bunch of ubuntu libraries installed

I reckon the path of least resistance would be:

• either install ubuntu desktop eg sudo apt-get install ubuntu-desktop, or
• install a vm

If it was me though, I'd probably just install the development libraries as each bug comes up. The development libraries all end in -dev, and often start in lib, eg you can type sudo apt-get install libzmq then hit the [tab] key, and up will pop some choices. Choose the one ending in -dev and you might be good. (In the specific though, I notice that on my machine I have libzmq3-dev, so you might need to try different version numbers :-P

I'm tempted to provide a list of the versions of libraries I have, but I reckon that's a security risk, but if you have some way for me to communicate that privately I can send that to you.

[jmsellier]

I will try on a native GNU/Linux machine with a more updated O.S. to see how it goes.. It seems that the virtual machine is complicating everything.. Thanks guys for your help anyway!

[hughperkins]

Ok. I reckon once you've figured it out on the native GNU/Linux machine (I assume you mean Ubuntu 14.04 by the way? This is the most standard torch distrib currently, AFAIK), then it will be fairly easy to get it working in Xubuntu VM too.

[hughperkins]

You can also try in a Docker container by the way, eg see https://hub.docker.com/r/hughperkins/cltorch-nvidia/ You'd need to either modify the Dockerfile to also install char-rnn, or else add char-rnn after starting the container. There's some torch containers created by kaixhin https://hub.docker.com/u/kaixhin/

[hughperkins]

Seems like this issue is really old and can be closed?

[jmsellier]

Yes it can be closed. Thanks.

Hi, I am trying to install iTorch, luacrypto is a dependency which I am not able to satisfy. The moonrock repositories are not accessible from my office. Can you suggest me a place from where I can download luacrypto?

The sources I have found till now either do not have a makefile or do not have a rockpec to use luarocks build luacrypto-git-1.rockspec. I installed image, moses, lzmq, lbase and uuid either through rockspec or src.rockspec

Thanks for the help
