 Assuming that the script is stored in the 'myscript.py' file it can be uploaded via command line and the `AI.SCRIPTSET` command as follows:

 This will store the PyTorch Script from 'myscript.py' under the 'myscript' key and will associate it with the CPU device for execution. Once loaded, the script can be run with the following:
