Commands

Executing commands

Executing commands in Sparkle is as simple as running them terminal for example:

sparkle initialise

Do note that when running on a cluster additional arguments may be needed, for instance under the Slurm workload manager. All CLI entries are placed in the sparkle package sparkle/CLI/$COMMANDNAME$.py the above command would change to something like:

srun -N1 -n1 -c1 path/to/package/sparkle/CLI/initialise.py

In the Examples/ directory a number of common command sequences are given. For instance, for configuration with specified training and testing sets see e.g. Examples/configuration_runtime.sh for an example of a sequence of commands to execute. Note that some command run in the background and need time to complete before the next command is executed. To see whether a command is still running the wait command can be used.

In the Output/ directory paths to generated scripts and logs are gathered per executed command.

Note

When typing a sparkle command name that consists of multiple words, both spaces and underscores are accepted as seperators.

List of Commands

Currently the commands below are available in Sparkle (listed alphabetically). Every command can be called with the –help option to get a description of the required arguments and other options.

Note

Arguments in [square brackets] are optional, arguments without brackets are mandatory. Input in <chevrons> indicate required text input, {curly brackets} indicate a set of inputs to choose from.
