Script

Script module is used for the doing some job that doesn’t need a dedicated module such as setting a number of parameters to a specific values, dumping observables to files, reading dataset + cleanup from files and whatever you see fit. The script can be arbitrary valid Python code and can access parts of GNA computational graphs that have been setup before calling script.

The module accepts the following positional arguments:

• file – the path to the Python script to be executed.

• args – the sequence of arguments that can be passed to the script body with index-based access.

See for examples of valid scripts in scripts/ui. The CLI usage:

python gna -- script ./path/to/script.py arg0 arg1 arg2

The parameters arg0, arg1, arg2 can be accessed from the script body as self.opts.args[0], self.opts.args[1], self.opts.args[2]
