如果〜/ .bashrc文件不存在，该如何在Google Colab上安装Torch？ [英] How could I install Torch on Google Colab if it does not exist the file ~/.bashrc?

问题描述

我想安装Torch（ http://torch.ch/docs/getting -started.html＃_ ）。但是，要安装Torch，我们需要在最后一步中运行以下命令 source〜/ .bashrc

I want to install Torch (http://torch.ch/docs/getting-started.html#_) on Google Colab. However, to install Torch, we need to run the following command at the final step source ~/.bashrc

要运行此命令在Google colab上，我使用的代码是

To run this command on google colab, the code I use is

%%bash
source ~/.bashrc

运行这些命令时，会收到警告

When I run those, I get a warning

bash：第1行：/ content /.bashrc：没有这样的文件或目录

bash: line 1: /content/.bashrc: No such file or directory

我也使用此命令查找bashrc

I also use this command to find bashrc

!find / -name '*bashrc'

这是我得到的输出

/root/.bashrc

/root/.bashrc

/etc/skel/.bashrc

/etc/skel/.bashrc

/ etc / bash.bashrc

/etc/bash.bashrc

/usr/share/base-files/dot.bashrc

/usr/share/base-files/dot.bashrc

/ usr / share / doc / adduser / examples / adduser.local.conf.examples / skel / dot.bashrc

/usr/share/doc/adduser/examples/adduser.local.conf.examples/skel/dot.bashrc

/usr/share/doc/adduser/examples/adduser.local.conf.examples/bash.bashrc

/usr/share/doc/adduser/examples/adduser.local.conf.examples/bash.bashrc

我尝试在所有这些路径上运行 source 命令。我也尝试使用 .profile 进行相同操作。但是尚未安装Torch。

I try to run the source command on all of those paths. I also try the same with .profile. But the Torch still has not been installed.

编辑：我不确定是否已安装Torch。这里的具体问题是我只是得到一个错误

I'm not sure if Torch is installed or not. The specific problem here is that I just get an error

找不到命令

command not found

每当我运行 th 或 luarocks

推荐答案

我通过python设置了所需的路径和环境

I set the required path and environment by python

#for Torch with Lua 5.3:
import os
os.environ['LUA_PATH'] = '/root/.luarocks/share/lua/5.3/?.lua;/root/.luarocks/share/lua/5.3/?/init.lua;/root/torch/install/share/lua/5.3/?.lua;/root/torch/install/share/lua/5.3/?/init.lua;/root/torch/install/lib/lua/5.3/?.lua;/root/torch/install/lib/lua/5.3/?/init.lua;./?.lua;./?/init.lua'
os.environ['LUA_CPATH'] ='/root/.luarocks/lib/lua/5.3/?.so;/root/torch/install/lib/lua/5.3/?.so;/root/torch/install/lib/lua/5.3/loadall.so;./?.so'
os.environ['PATH'] += ':/root/torch/install/bin'

if 'LD_LIBRARY_PATH' not in os.environ.keys():
  os.environ['LD_LIBRARY_PATH'] = ''
else:
  os.environ['LD_LIBRARY_PATH'] += ':'
os.environ['LD_LIBRARY_PATH'] +='/root/torch/install/lib'

if 'DYLD_LIBRARY_PATH' not in os.environ.keys():
  os.environ['DYLD_LIBRARY_PATH'] = ''
else:
  os.environ['DYLD_LIBRARY_PATH'] += ':'
os.environ['DYLD_LIBRARY_PATH'] +='/root/torch/install/lib'

if 'LUA_CPATH' not in os.environ.keys():
  os.environ['LUA_CPATH'] = ''
else:
  os.environ['LUA_CPATH'] += ';'
os.environ['LUA_CPATH'] += '/root/torch/install/lib/?.so'
