它有2个错误：
def displayImage(self):
qformat =QImage.Format_Indexed8
if len(self.image.shape)==3:
if self.image.shape[2] ==4:
qformat=QImage.Format_RGBA8888
else:
qformat=QImage.Format_RGB888
img = QtGui.QImage(self.image.data,
self.image.shape[1],
self.image.shape[0],
self.image.strides[0], # <--- +++
qformat)
img = img.rgbSwapped()
self.trainOpenImg.setPixmap(QPixmap.fromImage(img))
self.trainOpenImg.setAlignment(QtCore.Qt.AlignCenter)
另一方面，IDE在处理某些类型的错误时遇到问题，只能启动代码，因此，在这种情况下，建议在CMD或终端中运行它，因为它们会为您提供更多信息，例如，在这种情况下，错误消息为：
Traceback (most recent call last):
File "test.py", line 20, in loadClicked
self.loadImage(fname)
File "test.py", line 26, in loadImage
self.displayImage()
File "test.py", line 36, in displayImage
img=QtGui.QImage(self.image.data,self.image.shape[1],self.image[0],QtGui.QImage.Format_RGB888)
