I’m using Python 3.7.0 so I have multiple environments all on the same architecture with the same python release using anonconda.
What I discovered was that if I install the cryptography module in my dev / uat and then tried to synchronize to production server using rsync I ended up with errors relating to dependencies of the cryptography module. Specifically Cannot import name ‘_get_backend’ these errors appear to have gone away if I actually use pip install cryptography==3.2.1 instead of using rsync from an existing install machine. why is this the case? -- https://mail.python.org/mailman/listinfo/python-list
