问题
I am trying to install a luarocks package called stn. The official way of installing it is by running:
luarocks install https://raw.githubusercontent.com/qassemoquab/stnbhwd/master/stnbhwd-scm-1.rockspec
But this gives me the unfortunate, exacerbating error:
nvcc fatal : Value 'sm_20' is not defined for option 'gpu-architecture'
The only way to fix this, to my knowledge, is to manually change the CMakeLists.txt file from:
IF (CUDA_FOUND)
LIST(APPEND CUDA_NVCC_FLAGS "-arch=sm_20")
To:
IF (CUDA_FOUND)
LIST(APPEND CUDA_NVCC_FLAGS "-arch=sm_30")
So that meant I had to clone the repo into a local file, change the CMakeLists file, and then luarock make it. (As a disclaimer, to do this, I had to chown my entire user because of directory writing permissions luarocks just doesnt seem to have for whatever reason. How screwed am I?).
So, I was able to get it to install the .rockspec file by cding into the master directory and:
luarocks make stnbhwd-scm-1.rockspec
And this gave me this output:
$ luarocks make stnbhwd-scm-1.rockspec

stnbhwd scm-1 is now installed in /home/tex/torch/install/ (license: MIT)
Pay attention to the "warning" flags. I don't know why it does that, but I think it has some clear effect on the install, because when I load stn...:

sigh Does anyone know a fix? Is there a workaround? LuaRocks still works for installing packages, but maybe I am doing something wrong for installing local packages. Is there a way to install the stn package while changing the cmake file before it installs (instead of downloading the package and manually changing it that way)? I doubt it, but... :(
Edit: anyone reading this, please refer to this page. I essentialy said screw this and uploaded the edited repo onto my own github page. Now, I face a different error.
回答1:
I can see some mismatch in the paths. When you are installing stnbhwd you use prefix:
-DCMAKE_INSTALL_PREFIX="/home/tex/torch/install/lib/luarocks/rocks/stnbhwd/scm-1"
but looking to the warnings you get:
Warning: /home/tex/torch/install/share/lua/5.1/stnbhwd_scm_1-stn/init.lua is not tracked by this installation of LuaRocks
Shows that your LUA_PATH, LUA_CPATH is set to
/home/tex/torch/install/share/lua/5.1
Firstly, try the path that you used in prefix to add into LUA_PATH, LUA_CPATH
If that doesn't help try to specify the path in the Lua script:
-- add a new directory to the path
package.path = package.path .. ";/home/tex/torch/install/lib/luarocks/rocks/stnbhwd/scm-1/lua/stn/?.lua"
Alos, check this one
回答2:
I have got the same problem with you. And I find out that this is because I have install multi-version lua and during that time installed luarocks. At last i have remove the other lua version and reinstall luarocks, then use luarocks reinstall nn, everything goes well.
