torch入門筆記1:torch的使用

torch下的安裝和使用:

1.torch7的githubhttps://github.com/torch/torch7下安裝。

2.使用

luarocks install image 來安裝package

已經安裝的可以使用 luarock list 來查看

3.itorch的使用

https://github.com/facebook/iTorch

itorch是torch裡面的一個包，它能很輕松地顯示圖片、視頻和音頻等等。

需要先安裝ipython，然後你會發現還是無法用，比如th之後的命令行。

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

IPythonversion 2.2 or above (you can check your version of ipython using ipython --version)

ZeroMQ

# OSX

brew install zeromq

brew install openssl

luarocks install luacrypto OPENSSL_DIR=/usr/local/opt/openssl/

# Ubuntu

sudo apt-get install libzmq3-dev libssl-dev python-zmq

# Ubuntu 16

luarocks install lzmq

Installing iTorch

git clone https://github.com/facebook/iTorch.git

cd iTorch

luarocks 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 make

sudo chown -R $USER $(dirname $(ipython locate profile))

然後在命令行中輸入

itorch notebook # notebook mode

OR

itorch # console mode

OR

itorch qtconsole # Qt mode

跟ipython一樣debug。
