pyinstaller --noconsole filename.py
  • Once the file process is completed you will see new folders created. Navigate to dist folder -> project folder -> click on application (.exe) file.
  • At first, application may not work as expected, paste all the dependencies like images, text files, etc. inside that project folder.
