PyQt5 file dialog not showing up

I have connected a QPushButton to a method that call file dialog. The simplified code look like this:

def init_buttons(self):
    self.browse_button = QPushButton('&Browse')
    self.browse_button.clicked.connect(self.browse_file)

def browse_file(self):
    file_name = QFileDialog.getExistingDirectory()
    # Just for checking
    print(file_name)

Sometimes QFileDialog won't showing up. The process is indeed running, since the main class/widget doesn't response to my clicking. Sometimes it's showing up.

If QFileDialog doesn't show up, with pycharm, I have to stop and kill process to end the program. If I run the program directly from terminal, I have to manually end the running process to end the program. I can't figure out what causing this, since terminal not showing any exception or warning.

So, what is this?

The parameters for the getExistingDirectory were wrong. Please try this. Also, I have added further information in my pull request.

import os

def browse_file(self):
    self.save_dir = QFileDialog.getExistingDirectory(self, 
                      "Open Save Directory", os.path.expanduser('~'))
    print(self.save_dir)
