I am having this problem in spyder where, after I run my code and exit the gui.program, the kernel needs to manually be restarted after every time my code is ran, I sometimes even have to shut down spyder as kernel crashes. I am wondering if there is a way for the kernel to automatically be reset after closing the gui.program so I can run it again right after? This closes the program but doesn’t restart the kernel.
def EndProgram(self): print("Exiting Program") FigureCanvas.close(self) # behaviour to trigger on exit sys.exit() # exit

I found the issue, I had sys.exit() in my EndProgram() function as well as at the end of my code as seen here: sys.exit(app.exec_()). Once I took out the sys.exit() in my EndProgram function and changed sys.exit(app.exec_()) to sys.exit(), it is working perfect.
Original Code
if __name__ == '__main__': # from LoadIceberg2 import LoadData2 app = Application(sys.argv) gui = ProgramGUI() qr = gui.frameGeometry() cp = QDesktopWidget().availableGeometry().center() qr.moveCenter(cp) gui.move(qr.topLeft()) # app.processEvents() npics=8 gui.show() # behaviour to trigger on exit sys.exit(app.exec_())
New code
if __name__ == '__main__': # from LoadIceberg2 import LoadData2 app = Application(sys.argv) gui = ProgramGUI() qr = gui.frameGeometry() cp = QDesktopWidget().availableGeometry().center() qr.moveCenter(cp) gui.move(qr.topLeft()) # app.processEvents() npics=8 gui.show() # behaviour to trigger on exit sys.exit()
