Running Python file from Java class
I am trying to run a .py file from a java class and capture the output back to JAVA class. I am able to run the .py file successfully, but the problem is when I provide multiple third party imports in my .py file, then the JAVA class is not able to execute the python class and returning me null instance.
Location of .py file->/anaconda3/lib/python3.7/site-packages/try.py
JAVA code snippet:
public void exec_Python2() throws IOException
{
String d="python /anaconda3/lib/python3.7/site-packages/try.py Advertising";
Process p = Runtime.getRuntime().exec(d);
String s = null;
BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
List<String> resultsFound=new ArrayList<String>();
System.out.println("Here is the standard output of the command:n");
while ((s = stdInput.readLine()) != null) {
resultsFound.add(s.trim());
System.out.println(s);
}
}
PYTHON code snippet(try.py)
import sys
import cv2
import numpy as np
import pytesseract
from PIL import Image
arg1 = sys.argv[1]
def get_string(img_path):
print(img_path)
get_string(arg1)
But the same code works with CMD as:
python /anaconda3/lib/python3.7/site-packages/try.py ABCD
Output:
ABCD
java python import python-imaging-library jython
