How can I copy this data to shared memory so that the other process can obtain this data and convert to Python Object? 发自网易邮箱大师

It is not clear that what you want to do can be done in the general
sense.  See Alex Martelli's explanation here:
tackoverflow.com/questions/1268252/python-possible-to-share-in-memory-data-between-2-separate-processes/1269055#1269055

Any chance that instead of trying to share a PyDict you could share an
array?  If so, multiprocessing will work for you.

Or the last reference there is to some lower level inter process communication
things you can use in Python.  I have never tried them, so have no idea
how well written the code is.
