To run python externally, you need no libraries locally. You need them wherever python will run.

In Ignition, I would use java’s normal classes (starting with [ProcessBuilder](https://docs.oracle.com/javase/8/docs/api/java/lang/ProcessBuilder.html)) to spawn your platform’s `ssh` executable with suitable parameters (to connect to the remote system and launch your script), with a stream attached to the process’ `stdout`. Parse/decode that stream to get your result.

Use SSH keys to avoid any prompts while connecting. I recommend arranging for the selected key to only allow running the target script. (A limitation applied to the corresponding line of `authorized_keys` in the remote system.)
