itorch安装

itorch安装

安装完torch后，命令行输入th命令后进入命令行界面。但在进行训练时需要用到itorch，所以搜集到下面的资料并成功安装了itorch。

上面的命令执行成功后运行

luarocks make

执行成功后，命令行输入itorch，即可弹出itorch命令界面。

但在执行上面脚本的过程中遇到了很多问题，下面罗列安装时遇到的问题和解决方法。

1 ，在使用pip命令时出现错误，发现是python和pip版本不一致导致，根据链接中的步骤，pip install命令正常

2，ImportError: No module named enum

https://github.com/numba/llvmlite/issues/16
pip install enum34.

3，ImportError: cannot import name walk

pip install scandir

4， ImportError: No module named shutil_get_terminal_size

https://github.com/ipython/ipython/issues/9815

pip install backports.shutil_get_terminal_size

5，ImportError: No module named pygments.lexers

http://stackoverflow.com/questions/26215738/how-to-install-pygments-on-ubuntu

sudo apt-get install python-pygments
pip install package-name-here

6，ImportError: No module named decorator ?

sudo apt-get install python-decorator

7，ImportError: No module named notebook.notebookapp

8，运行命令显示图片时弹出错误，提示找不到libpng。

需要将image包重新安装一下
luarocks install image

备注：安装成功后后，在ubuntu的terminal中输出图像，命令行显示并不支持在当前命令行输出，改用itorch notebook 命令进入浏览器界面，输入相应脚本后图片正常显示。
