trigger source 设定为 0（line0）不生效

[KoU2N]

您好，请问如何设定硬触发，设定无法生效，触发断言函数。有什么好的设定方法吗？

    def __enter__(self) -> "HikCamera":
        """
        Camera initialization : open, setup, and start grabbing frames from the device.
        """

        # Open the camera with MVS SDK with exclusive access
        assert not self.MV_CC_OpenDevice(hik.MV_ACCESS_Exclusive, 0)

        # Initialize the camera with a fixes set of settings
        # TODO rember setting
        self.setitem("TriggerMode", hik.MV_TRIGGER_MODE_ON)
        self.setitem("TriggerSource", hik.MV_TRIGGER_SOURCE_SOFTWARE)#这里把hik.MV_TRIGGER_SOURCE_SOFTWAR设定为0无法生效。
        self.setitem("AcquisitionFrameRateEnable", False)
        self.setting()

        # Set the camera settings to the user-defined settings
        if self.setting_items is not None:
            if isinstance(self.setting_items, dict):
                self.setting_items = self.setting_items.values()
            for key, value in self.setting_items:
                self.setitem(key, value)
