Problems with pywintypes
Hello, I'm trying to learn how to use this library in python 3.6.4, win10, but this error appears :
Traceback (most recent call last):
File "C:\Python36\lib\multiprocessing\queues.py", line 234, in _feed
obj = _ForkingPickler.dumps(obj)
File "C:\Python36\lib\multiprocessing\reduction.py", line 51, in dumps
cls(buf, protocol).dump(obj)
_pickle.PicklingError: Can't pickle <class 'pywintypes.datetime'>: attribute lookup datetime on pywintypes failed
The code is very simple and runned using PyCharm, I was just following the tutorial to use OpenOPC.
import OpenOPC opc = OpenOPC.client() opc.connect('Matrikon.OPC.Simulation.1', 'localhost') print(opc.read('Random.Int1'))
Help please.
Trying using...
`import pywintypes
Due to picklingError with datetime
pywintypes.datetime = pywintypes.TimeType`
