torch入门笔记1:torch的使用

torch下的安装和使用:

1.torch7的github https://github.com/torch/torch7 下安装。

2.使用 

luarocks install image 来安装package

已经安装的可以使用 luarock list 来查看

3.itorch的使用

itorch是torch里面的一个包，它能很轻松地显示图片、视频和音频等等。
需要先安装ipython，然后你会发现还是无法用，比如th之后的命令行。
sudo apt-get install ipython-notebook

iTorch requires or works with

• Mac OS X or Linux (tested in Ubuntu 14.04 and Arch Linux)
• Torch-7
• IPython version 2.2 or above (you can check your version of ipython using ipython --version)
• ZeroMQ

# OSXbrew install zeromqbrew install opensslluarocks install luacrypto OPENSSL_DIR=/usr/local/opt/openssl/# Ubuntusudo apt-get install libzmq3-dev libssl-dev python-zmq# Ubuntu 16luarocks install lzmq

Installing iTorch

git clone https://github.com/facebook/iTorch.gitcd iTorchluarocks make 

If you have to use sudo for some reason (if you globally installed torch on Linux for example), use these commands:

sudo env "PATH=$PATH" luarocks makesudo chown -R $USER $(dirname $(ipython locate profile))

然后在命令行中输入

itorch notebook  # notebook modeOR  itorch  # console modeOR  itorch qtconsole  # Qt mode

跟ipython一样debug。
