它有2个错误：
- 您必须将传递
bytesPerLine
给QImage trainOpenImg
设置对齐方式时，您会输入更多的“ n” 。
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：
