Python script can't find dependencies when running from java code

I got server which is starting process with python script and when it is running I got error:

    Traceback (most recent call last):
  File "save_boxes.py", line 2, in <module>
    import cv2
ImportError: No module named cv2

In fact I got opencv2 installed and script is working when I run it from terminal, have no ideas how to fix it, appreciate any advices, thank you!

The code Im running the script is:

 Process process;
            try {
                final char dm = (char) 34;
                ProcessBuilder pb = new ProcessBuilder("./runC.sh", "myArg1", "myArg2");
                Map<String, String> env = pb.environment();
                env.put("VAR1", "myValue");
                env.remove("OTHERVAR");
                env.put("VAR2", env.get("VAR1") + "suffix");
                pb.directory(new File("/home/user/IdeaProjects/MyServer/"));
                process = pb.start();
        
                int exitCode = process.waitFor();
                if (exitCode != 0) {
                    throw new IOException("Command exited with " + exitCode);
                }
            } catch (Exception e) {System.out.println ("error message: " + e.getLocalizedMessage());}

The script code:

#!/bin/bash

python my_script.py

Try to use python3. On most of the systems, python is a link to the Python 2 interpreter. :)
