Error: No results matching query were found. for luarocks in ubuntu

Question

I'm totally new in Lua. And here is what I've done on my new virtual Ubuntu. First I install the lua-5.3.4 which is download from their official website.

make linux
make install

And this is the README.md of the dependency lib suggesting I do.

luarocks install torch
luarocks install nn
luarocks install dpnn
luarocks install torchx
luarocks install rnn

However, it always return me this error message no matter where I use them.

Error: No results matching query were found.

So I follow the suggestion I found on here to install torch from http://torch.ch/docs/getting-started.html

This is what I do

git clone https://github.com/torch/distro.git ~/torch --recursive
cd ~/torch; bash install-deps;
./install.sh
source ~/.bashrc

All of this commands are under mycount

vera@ubuntu:~/Documents/relation inference$

Then I try again to install the dependency and fail again.

sudo luarocks install rnn
sudo luarocks install nn
sudo luarocks install torch

I switch to the root count by sudo su. Then while I do luarocks install nn again. I got this:

root@ubuntu:/home/vera/Documents/relation inference# luarocks install nn
Installing https://rocks.moonscript.org/nn-1.0.4-1.src.rock...
Using https://rocks.moonscript.org/nn-1.0.4-1.src.rock... switching to 'build' mode

lnn.c:4:23: fatal error: nanomsg/nn.h: 没有那个文件或目录(this means :no that file or the dict)
compilation terminated.

Error: Build error: Failed compiling object lnn.o

While I use the other command under root, I still got the same error message.

root@ubuntu:/home/vera/Documents/relation inference# luarocks install rnn
Error: No results matching query were found.

root@ubuntu:/home/vera/Documents/relation inference# luarocks install torch
Error: No results matching query were found.

root@ubuntu:/home/vera/Documents/relation inference#  luarocks install torch7-master
Error: No results matching query were found.

I already downloaded the dependency from GitHub.

Try sudo luarocks search --all to see the packages that you can install. Since torch has its own rocks make sure that the luarocks you are executing is the torch one and not your system's. – Wiretap

@ManuelLagunas Why do you need to be SU to do a search of installable packages? – Recapitulate

Finally I solved my issues by this way.

Error: No results matching query were found. for luarocks in ubuntu you can find the detail of the solution on my blog.

The follow is what I did.

---

First I find that I didn't install torch in fact though I did what the offical web site told me and installed it for 3 times.(And I still don't know why.) you can test if you have successed install the torch byth

> th
  ______             __   |  Torch7 
 /_  __/__  ________/ /   |  Scientific computing for Lua. 
  / / / _ \/ __/ __/ _ \  |  Type ? for help 
 /_/  \___/_/  \__/_//_/  |  https://github.com/torch 
                          |  http://torch.ch 

Then maybe you will still find the command luarocks install xxx useless.Continue.

this is the solution which I finally found useful.(This is in Chinese.If you don't understand,you can see what I write down.)

Download all of the dependency on github,unzip,and cd into the dict.

luarocks install nn-master/rocks/nn-scm-1.rockspec
luarocks install rnn-master/rocks/rnn-scm-1.rockspec

the most important point is that you need to find where is the .rockspec

Here is some dependencies's location.And you may find they are not always in a same format.

luarocks install torchx-master/torchx-scm-1.rockspec
luarocks install Moses-master/rockspec/moses-1.4.0-1.rockspec
luarocks install dpnn-master/rocks/dpnn-scm-1.rockspec
luarocks install rnn-master/rocks/rnn-scm-1.rockspec
luarocks install optim-master/optim-1.0.5-0.rockspec

During install,this is what you may get.

pnn-scm-1.rockspec
Using dpnn-master/rocks/dpnn-scm-1.rockspec... switching to 'build' mode

Missing dependencies for dpnn:
moses >= 1.3.1

So just go to the github, find the dependency it ask for.so loop.As you can see, here infact I just need rnn, nn, optim, torch, the other is all this dependency ask for.

Make sure the dependency is already installed in your dict.

Hope to help you . XD

Answer 2

To solve it follow these steps:

sudo apt install luarocks
sudo ~/torch/install/bin/luarocks install nn

Hebron

This works, but why? Isn't ./install.sh supposed to add Torch to the PATH variable ? – Recapitulate

Answer 3

You should use the luarocks provided by torch.

Include ~/torch/install/bin in your $PATH as the first entry. You will then be able to use luarocks install without such problem.
