Answer a question

My program in tkinter is working well when I am running it using PyCharm, when I am creating .exe file using pyinstaller,
pyinstaller -i"icon.ico" -w -F script.py
I have no errors. I am pasting script.exe in same folder as my script.py, and after running it I think in step where subprocess is, it is not answering, because I haveprint before subprocess line and its working.

Anyone know why?

This is the line with subprocess:

import subprocess
from subprocess import Popen, PIPE
 s = subprocess.Popen([EXE,files,'command'],shell=True, stdout=subprocess.PIPE)

EDIT:

same problem with:

s = subprocess.check_output([EXE,files,'command'],shell=True, stderr=subprocess.STDOUT)

Problem was solved by not using -w command for generating exe file from .py script.
