pyqt5 TypeError: getOpenFileName(parent: QWidget = None, caption: str = '', directory: str = '', fil

今天在用pyqt5打开文件的时候，出现了下面的错误：

Traceback (most recent call last):
  File "/Users/admin/PycharmProjects/test_qt/src/tooth.py", line 20, in openimage
    imgName, imgType = QFileDialog.getOpenFileName( '选择文件', '', "*.jpg;;*.png;;All Files(*)")
TypeError: getOpenFileName(parent: QWidget = None, caption: str = '', directory: str = '', filter: str = '', initialFilter: str = '', options: Union[QFileDialog.Options, QFileDialog.Option] = 0): argument 1 has unexpected type 'str'

解决方法

imgName, imgType = QFileDialog.getOpenFileName(None,'选择文件','',"*.jpg;;*.png;;All Files(*)")
