我有一个RIGOL DP832A电源，仪器无法正常关闭，并且会忽略异常：
在以下情况中忽略异常：追溯（最新 最后调用）：文件“ C：\ Program Files （x86）\ Python36-32 \ lib \ site-packages \ pyvisa \ resources \ resource.py”， 第108行，位于 del 文件“ C：\ Program Files （x86）\ Python36-32 \ lib \ site-packages \ pyvisa \ resources \ resource.py”， 236行，在关闭文件“ C：\ Program Files中 （x86）\ Python36-32 \ lib \ logging__init __。py“，第1293行，在调试文件中 “ C：\ Program Files（x86）\ Python36-32 \ lib \ logging__init __。py”，行 1546，在isEnabledFor TypeError中：实例之间不支持'> =' 'int'和'NoneType'的
在调试错误时，当我调用psu.close（）函数时，它将调用“ C：\ Program Files（x86）\ Python36-32 \ Lib \ site-packages \ pyvisa \ resources \ resource的关闭函数.py“ 并检索以下消息：无法从239 ” logger.debug（'％s-is closeed'，self._resource_name，extra = self ._logging_extra）” 。除了具有同一个资源管理器的PSU之外，我还有多个仪器连接，但是首先我需要正常退出PSU的过程。我通过以下命令连接了Rohde和Shwarz FSP13： self.interface = visa_rm.open_resource（f“ RSIB :: {地址} :: INSTR”，resource_pyclass = MessageBasedResource） 代码：
self.interface1 = visa_rm.open_resource(f"TCPIP::{address}::INSTR")
self.interface1.close()
def cleanup(self, msg_q):
self.dut.close()
self.psu.set_output(DUT_PSU_CHANNEL, False)
self.psu.close()

试图更新到最新的PyVISA 1.9仍然是同样的问题。 更新到1.9后，这是日志：
