[me@bw ~]$ bw unlock
? Master password: [hidden]
Your vault is now unlocked!

To unlock your vault, set your session key to the `BW_SESSION` environment variable. ex:
$ export BW_SESSION="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxf2yth/1R3/yhgB+irDESoVS3Ior9rzHoJ2kUQejQ=="
> $env:BW_SESSION="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxf2yth/1R3/yhgB+irDESoVS3Ior9rzHoJ2kUQejQ=="

You can also pass the session key to any command with the `--session` option. ex:
$ bw list items --session xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxf2yth/1R3/yhgB+irDESoVS3Ior9rzHoJ2kUQejQ==
[me@bw ~]$
[me@bw ~]$ echo $BW_SESSION
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxf2yth/1R3/yhgB+irDESoVS3Ior9rzHoJ2kUQejQ==
[me@bw ~]$ bw-simple get [FIELD=password]  c9d2fde3-b9c3-4cb5-a94d-aa4d015bb120

I'm also seeing this problem

[lxop]

It is caused by an import loop between ContainerService->CryptoService->CipherString->ContainerService

[lxop]

Aaaand it's only a problem with Python 3.6 (and below), which aren't supported (at least according to PyPI), so nothing to see here!
It might pay to be clearer about version requirements in the readme though.

Install python 3.8.1 on centos 7.7.
