Using pandas and other libraries with Java's ScriptEngine

I'm running Python through Java's Scripting Engine. The basic hello world is working well, but it fails when I import pandas in the python script.

    StringWriter stringWriter = new StringWriter();
    ScriptContext scriptContext = new SimpleScriptContext();
    scriptContext.setWriter(stringWriter);
    ScriptEngineManager manager = new ScriptEngineManager();

    ScriptEngine engine = manager.getEngineByName("python");

ImportError: No module named pandas

Is there a way to install it for Scripting Engine?

I have pandas on my machine installed through command line but that's not the python being used here.

perhaps you need to run on cmd line: pip install pandas – Ruperto Aug 30 '20 at 13:47
Its already installed through cmd line and is working outside. – Palak Bansal Aug 30 '20 at 13:53
uh okay, perhaps https://stackoverflow.com/questions/27235286/call-python-code-from-java-by-passing-parameters-and-results might help – Ruperto Aug 30 '20 at 14:13
I've followed the same approach. Pandas doesn't work for it. – Palak Bansal Aug 30 '20 at 14:20
maybe, we can find the path of python.exe that java is using, by letting the engine print: import sys print(sys.executable) – Ruperto Aug 30 '20 at 14:41
Prints "None" for sys.executable – Palak Bansal Aug 30 '20 at 14:58
'hope someone else would give some ideas :) i wonder what the following would tell us about whether pandas is actually loaded but not accessible and show the path to pandas ... please try via ScriptEngine: import sys import pandas print(sys.modules['pandas']) – Ruperto Aug 31 '20 at 03:09
