未找到模块“cudnn”：未找到 cudnn 的 LuaRocks 模块

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，它给出了输出：

Error: No results matching query were found.

如何解决这个依赖问题。

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

即为它创建一个新环境。
