Can't share data between Unity and python

[DEKAGATO]

Need your help, I found out your amazing solution to communicate from Unity and python, but when i create in unity:
sm = new SharedMemory("test", 100, true, 60);
and in python:
sm0 = SharedMemory("test", 100, False, 30)
unity freeze about 1mins and after that:
Exception: Python has stopped.
PythonUnitySharedMemory.SharedMemory.WaitUnblocked () (at Assets/com.python-unity-shared-memory/Runtime/Core.cs:193)

Thanks for your help
