I cannot install specific Luarocks. I want to determine key points in 3D hand scans using a CNN. Therefore, I want to get V2V-PoseNet running. However, I run into a problem and the researcher suggested me to try:
$luarocks install cutorch
$luarocks install cunn
Unfortunately, I get the error that I have no writing permissions. When executing with sudo, I get:
Error: No results matching query were found.
I have installed Torch correctly (th works) and I did a clean install of Luarocks:
$th

$sudo apt-get install luarocks
and then try to install the rocks:
$sudo luarocks install cutorch
$sudo luarocks install cunn
Without the sudo command, it is not working. The installation commands above return both Error: No results matching query were found. Someone with a similar problem was suggested to install the rock manually. If I manually download the cutorch-master, start a terminal from the folder /rocks and run
$luarocks install cutorch-1.0-0.rockspec
I get the error that my user 'does not have write permissions in /usr/local/lib/luarocks/rocks'. When I try to install with sudo, I get Missing dependencies for cutorch 1.0-0: torch >= 7.0 (not installed). I tried to modify .bashrc, but that was not successful, although I was able to repair that in the mean time.
By the way, Lua itself is installed:
$lua
Lua 5.1.5 Copyright (C) 1994-2012 Lua.org, PUC-Rio
I am running this from Ubuntu 18.04.
How to install cutorch and cunn with Luarocks?
I finally found the solution. I set up Ubuntu 18.04 again and installed Torch according to the documentation.
git clone https://github.com/torch/distro.git ~/torch --recursive
cd ~/torch; bash install-deps;
./install.sh
source ~/.bashrc
Then, I installed CUDA and ran it:
sudo sh cuda_9.2.148_396.37_linux.run
After I intalled cuDNN, I was able to run the commands above.
