lua - 找不到模块 'cudnn' :No LuaRocks module found for cudnn

Question

在 Ubuntu 16.04 上按照标准命令安装 Lua 和其他依赖项:

conda install lua=5.2 lua-science -c alexbw

我在行中遇到错误:

require 'cudnn'

错误是:`

尝试使用命令 luarocks install cudnn 安装 cudnn，结果如下:

Error: No results matching query were found.

如何解决此依赖性问题。

Answer 1

它也可以从 the alexbw channel 获得, 所以如果你已经安装了 lua-science, 只需

conda install -c alexbw lua-cudnn

如果您是从头开始安装，这似乎是一个非常专业的安装，所以我的建议是

conda create -n lua-sci -c alexbw lua=5.2 lua-science lua-cudnn

也就是为它创造一个新的环境。
