Question

我正在尝试安装名为stn的luarocks包。安装它的官方方式是运行：

luarocks install https://raw.githubusercontent.com/qassemoquab/stnbhwd/master/stnbhwd-scm-1.rockspec

但这给了我一个不幸的，加剧的错误：

nvcc fatal   : Value 'sm_20' is not defined for option 'gpu-architecture'

据我所知，解决此问题的唯一方法是手动更改CMakeLists.txt文件：

IF (CUDA_FOUND)
  LIST(APPEND CUDA_NVCC_FLAGS "-arch=sm_20")

要：

IF (CUDA_FOUND)
  LIST(APPEND CUDA_NVCC_FLAGS "-arch=sm_30")

这意味着我必须将repo克隆到本地文件中，更改CMakeLists文件，然后luarock制作它。（作为免责声明，要做到这一点，我必须chown我的整个用户，因为目录写入权限luarocks似乎无论出于何种原因。我怎么搞砸？）。

所以，我能够通过cding到主目录来安装.rockspec文件，并且：

luarocks make stnbhwd-scm-1.rockspec

这给了我这个输出：

$ luarocks make stnbhwd-scm-1.rockspec 
cmake -E make_directory build && cd build && cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH="/home/tex/torch/install/bin/.." -DCMAKE_INSTALL_PREFIX="/home/tex/torch/install/lib/luarocks/rocks/stnbhwd/scm-1" && make

注意“警告”标志。我不知道为什么会这样，但我认为它对安装有一些明显的影响，因为当我加载stn ...时：

叹息有人知道修复吗？有解决方法吗？ LuaRocks仍然适用于安装软件包，但也许我在安装本地软件包时出错了。有没有办法在安装之前更改cmake文件时安装stn包（而不是下载包并手动更改它）？我对此表示怀疑，但...... :(

编辑：阅读此内容的任何人，请参阅this page。我essentialy说拧了这个并将编辑后的repo上传到我自己的github页面。现在，我面临着一个不同的错误。

Answer 1

我可以看到路径中的一些不匹配。当您安装stnbhwd时，请使用前缀：

-DCMAKE_INSTALL_PREFIX="/home/tex/torch/install/lib/luarocks/rocks/stnbhwd/scm-1"

但是要注意你得到的警告：

Warning: /home/tex/torch/install/share/lua/5.1/stnbhwd_scm_1-stn/init.lua is not tracked by this installation of LuaRocks

显示您的LUA_PATH，LUA_CPATH设置为

/home/tex/torch/install/share/lua/5.1

首先，尝试在前缀中使用的路径添加到 LUA_PATH，LUA_CPATH

如果这无助于尝试在Lua脚本中指定路径：

-- 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，检查this一个

Answer 2

我也遇到了同样的问题。我发现这是因为我安装了多版本lua，并且在此期间安装了luarocks。最后，我删除了其他lua版本并重新安装了luarocks，然后使用luarocks重新安装nn，一切顺利。

警告：此LuaRocks安装不会跟踪file.lua
