Question

我有一个pyqt应用程序，单击该按钮即可启动pptk点云查看器（查看器窗口作为独立的操作系统进程启动）。当我通过python解释器运行应用程序时，此方法运行良好，但是当我使用Pyinstaller冻结它并运行冻结的应用程序时，查看器窗口不会启动。没有错误消息，什么也没有发生。我在Windows 10系统上。

我认为这可能与this有关，因为我似乎没有那个图书馆。还是其他进程阻止了查看器的启动？任何想法将不胜感激。

代码的相关部分如下：

class Window(QWidget):
    def __init__(self):
       super().__init__()    

       if not QApplication.instance():
          app = QApplication(sys.argv)
       else:
          app = QApplication.instance()             

       # Define variables which will hold the picked GCPs #    
       self.GCPs_im = np.empty([0,2])
       self.GCPs_lidar = np.empty([0,3])
       #################################################### 

       # Right contents box setup #
       self.introLab = QLabel('Welcome to the GCP picking module! Here, you will be guided through the process of co-locating points in the image and the lidar observations. You must identify the correspondence of at least 3 unique points for the calibration to work.')
       self.introLab.setWordWrap(True)
       self.goLab = QLabel('Ready to co-locate a point?:')
       self.goBut = QPushButton('Go')

       self.rightGroupBox = QGroupBox()
       self.grd = QGridLayout()
       self.grd.addWidget(self.goBut,7,3,1,1)
       self.grd.addWidget(self.goLab,7,0,1,1)
       self.grd.addWidget(self.introLab,0,0,1,4)
       self.grd.addWidget(self.canvas,2,0,4,4)
       self.rightGroupBox.setLayout(self.grd)
       ###############################

       # Connect widgets with signals #
       self.goBut.clicked.connect(self.getPoints1)
       ################################

       # Instantiate worker threads #
       self.worker = pptkWindowWorker()
       self.worker.finishSignal.connect(self.on_CloseSignal)
       ##############################


       # Full widget layout setup #
       fullLayout = QGridLayout()
       fullLayout.addWidget(leftGroupBox,0,0,2,2)
       fullLayout.addWidget(self.rightGroupBox,0,3,2,4)
       self.setLayout(fullLayout)
       self.show()
    ############################


   def getPoints1(self):

      self.worker.start()

   def on_CloseSignal(self):

      self.goBut.setParent(None)
      self.goLab.setParent(None)
      self.introLab.setParent(None)
      self.helpBut = QPushButton('Help')


class pptkWindowWorker(QThread):

   finishSignal = pyqtSignal('PyQt_PyObject')

   def __init__(self):
       super().__init__()

   def run(self):

       print('Thread Started')

       f = open('lidarPC.pkl','rb')
       pc = pickle.load(f)
       v = pptk.viewer(pc,pc.iloc[:,2])
       v.set(point_size=0.1,theta=-25,phi=0,lookat=[0,0,20],color_map_scale=[-1,3],r=0)


       self.finishSignal.emit(1)    

       print('Thread Done')  




if __name__ == '__main__':
   import sys
   from PyQt5 import QtWidgets

   if not QtWidgets.QApplication.instance():
       app = QtWidgets.QApplication(sys.argv)
   else:
       app = QtWidgets.QApplication.instance()

   w = WelcomeWindow()
   sys.exit(app.exec_())

pyqt应用程序不会启动pptk查看器（独立的OS进程）
