This might be because Jython doesn't read the Python packages from the place where you might have installed them in Python through CLI.

One way to solve your problem is to install Paramiko in during the execution of the code:

PythonInterpreter interp = new PythonInterpreter();

interp.exec("from pip._internal import main as pip_main");
interp.exec("pip_main(['install', 'paramiko'])")
interp.exec("import paramiko");

Or

PythonInterpreter interp = new PythonInterpreter();

interp.exec("from pip import main as pip_main");
interp.exec("pip_main(['install', 'paramiko'])")
interp.exec("import paramiko");

Refer to Installing python module within code for more ways to install packages in code depending on your python version. The above should hold good for Python 2.7, which is what I believe Jython is based on.
