Get start

First of All

1. Create user account with the administrator of lab servers.

2. Acquire information of servers (ip, name, computing power)

Important !!!

1. Ctrl-Z is used to put process in background. To terminate process, using Ctrl-C.

2. DO NOT eat all of memory, it's very rare to do this, and should be able to avoid using too much memory in most of the cases. Like:

   1. If read a big file, read it line by line instead of read the whole file at once.

   2. Consider generator of python when dealing with large file or list.

   3. Avoid transform whole dataset into embeddings. Transform them in forward function of model.

3. Feel free to ask questions! Even if some answer is on this guide, labmates are still willing to point out for you.

In case you don't know these

• terminal usage

  • or try 鳥哥 (and it contains all stuff below and even more...)

• Begin SSH connection

• Git & GitHub

• TMUX

  • Be noticed that your account will go along with a special tmux.rc (config file of tmux). I believe the main difference is the prefix is C-a instead of C-b. Reach out any labmates if you found anything wired.

• Vim

  • Interactive Vim tutorial

  • Vim basic

• Pip (or pip3 or pip3.x)

$ pip3 -v                                           show the current version of pip
$ pip3 -h (help)                                    show pip commands
$ pip3 install [options] <package>                    install package
