安装Torch7.iPython安装错误(mac)

Question

我正在尝试在我的Mac上安装Torch7,但此时安装暂停:

Not updating your shell profile.
You might want to 
add the following lines to your shell profile:

export PATH=/Users/khsiddiqui/torch/install/bin:$PATH
export LD_LIBRARY_PATH=/Users/khsiddiqui/torch/install/lib:$LD_LIBRARY_PATH 
export    DYLD_LIBRARY_PATH=/Users/khsiddiqui/torch/install/lib:$DYLD_LIBRARY_PATH 

不确定这意味着什么.上面我收到了以下输出

echo "Error: could not find ipython in PATH. Do you have it installed?"
   fi

但是我安装了iPython,因为我可以确认:

No update necessary, 'ipython' is up-to-date.
ipython-3.0.0-3.egg was installed on: Thu Apr  9 18:12:32 2015

Answer 1

我有类似的问题并解决了它,也许它可以帮助别人.

这是第二个安装脚本的结束,命令"th"无效:

Not updating your shell profile.
You might want to
add the following lines to your shell profile:

. /Users/myusername/torch/install/bin/torch-activate

本文介绍了您的shell配置文件的组织方式:https://serverfault.com/questions/110065/what-profile-is-my-current-shell-using

我意识到在我的用户文件夹/ Users/myusername /我有一个".bash_profile"文件,我在里面粘贴了"./ Users/myusername/torch/install/bin/torch-activate"行但是没有用(命令" "终端没有认可".

因此,在同一个/ Users/myusername /文件夹中,我创建了一个".profile"文件并在其中粘贴了"./ Users/myusername/torch/install/bin/torch-activate"行.

那么命令"th"工作正常;)

首先，IPython 可能已安装，但安装过程中看不到。

如果您which ipython在 shell 提示符下输入，它会告诉您它的安装位置。然后echo $PATH将显示您的 PATH 变量，该变量应包含包含 IPython 的目录。如果不是，那么您必须编辑 .bashrc 文件中的 PATH 语句才能添加它。

第二个.bashrc文件是 shell 启动时运行的文件，应该位于您的主目录中，因此cd在 shell 提示符下输入即可到达该目录。然后使用文本编辑器（例如 Text Edit）对其进行编辑。在您的情况下，您没有.bashrc文件，而是在名为.profile. 您可能应该检查一下其中的内容。

最后，我不会在 IPython 中运行任何这些命令。仅从 shell 运行它们（以及 Torch 安装过程）。

此外，我注意到您有一个名为“anaconda”的文件。你安装了“Anaconda”吗？
