Lab wk01

Goals

After this first lab every student should have installed and working on their laptops:

• R
• RStudio
• some R packages TBD
• Java (needed for h2o)
• h2o (from R, run this to test if it is working)

should have

• a github account
• an AWS account with $100 worth of free student credits

should be able to

• create a simple Rmarkdown file, run it in RStudio and get html report
• upload files to their github account
• start an EC2 instance, create an image, stop/restart, configure security groups (open ports)
• use ssh and basic Unix/Linux command line
• do same work in RStudio server on EC2 and in RStudio locally on laptop

On EC2 one can use this AMI with R and RStudio server already installed. Please change the default password for the rstudio user (e.g. as described at the previous link).

Warning: The Rstudio connection (from your browser) does not use SSL, therefore don't use this server on projects requiring security (e.g. with confidential data) or set up SSL connection (https) before you connect to RStudio for the very first time.

Java and h2o

Install Java (required by h2o) via command line (e.g. by logging in via ssh):

sudo apt-get install default-jre

(then you can install h2o as an R package from RStudio).

lightgbm

install.packages("devtools")
devtools::install_github("Microsoft/LightGBM", subdir = "R-package")

(might need cmake: sudo apt-get install cmake)

TODO

AMI with CUDA, cuDNN. Install RStudio keras. Other DL libs?
