That is strange.

The "_lib" actually comes from "cryptography.hazmat.bindings._openssl".
Apparently, it defines quite some of the SSL related constants
but not "SSL_ST_INIT".

A potential reason could be that
a wrong version of the "cryptography" packages is used, maybe
due to a bad "PYTHONPATH" or "sys.path" value. Import "cryptography"
and look at its "__file__" to verify where is comes from.

Another potential reason: the contents of "_lib" might depend
on the openssl system library. Then an incompatible version
of this library might cause the problem.
