    from shared_ndarray import SharedNDArray

^^^^^^^^^

posix_ipc dropped support for Python 2.7 a while ago. You can install an older version if you need Python 2.7 support, as documented in the README: https://github.com/osvenskan/posix_ipc/blob/master/README.md#python-27-support

I checked the pkg vesion is 1.0.4. It should be suitable to run on python2.7.

I just updated posix-ipc from 1.0.4 to 1.0.5, and the issue was solved. Now I can import this pkg on py2.7 Thank U🙌😉
