将包导入 Torch 时出错

Question

我刚刚安装了 Torch7 as per the instructions。但是，我无法通过命令行解释器移植任何包：

kamransiquisMBP:~ khsiddiqui$ th

  ______             __   |  Torch7

    th> require "nn"

        ...rs/khsiddiqui/torch/install/share/lua/5.1/trepl/init.lua:384: 
        in function 'require' [string "_RESULT={require "nn"}"]:1: in main chunk   
        [C]: in function 'xpcall' 
        ...rs/khsiddiqui/torch/install/share/lua/5.1/trepl/init.lua:651:

        in main chunk
        [C]: at 0x010fc1cd00    
    th> 1 + 1
    2

在解释器之外，（仅从命令行）我运行命令 luarocks install nn，但仍然存在上述相同的错误。

很想安装 Torch7，运行！

嗨，@deltheil ...

kamransiquisMBP:~ khsiddiqui$ luajit -ltorch
luajit: /usr/local/share/lua/5.1/torch/init.lua:11: cannot load
 '/usr/local/lib/lua/5.1/libtorch.so'
stack traceback:

    [C]: at 0x010a50bd00

运行 luajit...

之后

th> ok, err = pcall(require, 'libtorch')
th> print(ok, err)
false   error loading module 'lib torch' from file

感谢@deltheil 的帮助！

As per the instructions on this page，对我有用的（在 Mac OSX 上）是：

找到并删除文件 ./pkg/torch/lib/TH/cmake/FindMKL.cmake ...
通过运行 ./clean.sh; ./install.sh ...

在那之后 Torch 就是预期的运行 :-)。我正在学习机器学习！
