Prerequisites

• Java 8 (>= 8)

• Scala 2.12.8 (>= 2.12.8)

Installation requires a recent ScalaTion distribution (>= 1.3) from here. Once you have ScalaTion, make sure the SCALATION_JARS environment variable is set appropriately before continuing. This can be done individually, as seen here:

It is important to note that this is the most important step, if the environment variable is not correct, the program will not run properly.

Steps (Terminal):

• Find where you downloaded your copy of ScalaTion.

• Use pwd command to get the path location.

• Copy the path to use in the next steps.

Run the following commands with “/path/to/” replaced with the file path from the pwd command:

$ export SCALATION_JARS=/path/to/scalation_mathstat.jar
$ export SCALATION_JARS=/path/to/scalation_modeling.jar:$SCALATION_JARS

Example:

$ export SCALATION_JARS=/home/mepcotterell/Downloads/scalation_1.4/scalation_mathstat.jar
$ export SCALATION_JARS=/home/mepcotterell/Downloads/scalation_1.4/scalation_modeling.jar:$SCALATION_JARS

It can also be done with a single command if you know the path to the scalation_models directory:

$ export SCALATION_JARS=$(find /path/to/scalation_models/lib | grep .jar | paste -sd ":" -)

To install Scalation Kernel from PyPI, you can use the following commands:

$ python3 -m pip install -U scalation_kernel
$ python3 -m scalation_kernel.install

More installation options are presented in the Installation Guide, including deployment options for Python virtual environments and Docker containers.
